Project Atomistic Spin-Dynamics; Methodology and Applications
Researcher (PI) Olof Ragnar Eriksson
Host Institution (HI) UPPSALA UNIVERSITET
Call Details Advanced Grant (AdG), PE3, ERC-2009-AdG
Summary Our aim is to provide a theoretical framework for studies of dynamical aspects of magnetic materials and magnetisation reversal, which has potential for applications for magnetic data storage and magnetic memory devices. The project focuses on developing and using an atomistic spin dynamics simulation method. Our goal is to identify novel materials and device geometries with improved performance. The scientific questions which will be addressed concern the understanding of the fundamental temporal limit of magnetisation switching and reversal, and the mechanisms which govern this limit. The methodological developments concern the ability to, from first principles theory, calculate the interatomic exchange parameters of materials in general, in particular for correlated electron materials, via the use of dynamical mean-field theory. The theoretical development also involves an atomistic spin dynamics simulation method, which once it has been established, will be released as a public software package. The proposed theoretical research will be intimately connected to world-leading experimental efforts, especially in Europe where a leading activity in experimental studies of magnetisation dynamics has been established. The ambition with this project is to become world-leading in the theory of simulating spin-dynamics phenomena, and to promote education and training of young researchers. To achieve our goals we will build up an open and lively environment, where the advances in the theoretical knowledge of spin-dynamics phenomena will be used to address important questions in information technology. In this environment the next generation research leaders will be fostered and trained, thus ensuring that the society of tomorrow is equipped with the scientific competence to tackle the challenges of our future.

Project Aqueous Supramolecular Polymers and Peptide Conjugates in Reversible Systems
Researcher (PI) Oren Alexander Scherman
Host Institution (HI) THE CHANCELLOR MASTERS AND SCHOLARSOF THE UNIVERSITY OF CAMBRIDGE
Call Details Starting Grant (StG), PE5, ERC-2009-StG
Summary Supramolecular polymers are of major interest in the field of self assembly with a promising outlook in areas of viscosity modification, compartmentalized architectures, bio-conjugates and drug-delivery applications. They are dynamic macromolecular materials prepared by simple mixing of relatively small components bearing complementary or self-complementary recognition motifs. A major limitation in the field, however, has been access to synthetic systems capable of undergoing self assembly in an aqueous environment. This research proposal develops well-defined, self-organizing macromolecular structures that will overcome this limitation by focusing on systems that rely on several non-covalent interactions occurring in concert rather than on single interactions alone. The envisioned supramolecular polymers and bio-conjugates are designed as dynamic water-soluble smart materials, whose architectures can be controlled and exhibit reversibility upon exposure to external stimuli such as electrochemical, temperature or pH changes. Molecular recognition events occurring between functional handles on both synthetic and bio-polymers will be investigated in order to control the formation of desired functional architectures through stoichiometrically controlled complexation. Preparation of synthetic core motifs to assemble discrete peptide aggregates such as the dimeric through hexameric oligomers of amyloid-beta(40/42) will lead to structural elucidation and insight into several peptide misfolding pathologies like Alzheimer's or Parkinson's disease.

Project Structure-Function Analysis of the Chemokine Interactome for Therapeutic Targeting and Imaging in Atherosclerosis
Researcher (PI) Christian Weber
Host Institution (HI) LUDWIG-MAXIMILIANS-UNIVERSITAET MUENCHEN
Call Details Advanced Grant (AdG), LS4, ERC-2009-AdG
Summary Atherosclerosis is characterized by chronic inflammation of the arterial wall. Mononuclear cell recruitment is driven by chemokines that can be deposited e.g. by activated platelets on inflamed endothelium. Chemokines require oligomerization and immobilization for efficient function, and recent evidence supports the notion that heterodimer formation between chemokines constitutes a new regulatory principle amplifying specific chemokine activities while suppressing others. Although crucial to inflammatory disease, this has been difficult to prove in vivo, primarily as chemokine heterodimers exist in equilibrium with their homodimer counterparts. We introduce the paradigm that heteromerization of chemokines provides the combinatorial diversity for functional plasticity and fine-tuning, coining this interactome. Given the relevance of chemokine heteromers in vivo, we aim to exploit this in an anti-inflammatory approach to selectively target vascular disease. In a multidisciplinary project, we plan to generate covalently-linked heterodimers to establish their biological significance. Obligate heterodimers of CC and CXC chemokines will be designed using computer-assisted modeling, chemically synthesized and cross-linked, structurally assessed using NMR spectroscopy and crystallography, and subjected to functional characterization in vitro and reconstitution in vivo. Conversely, we will develop cyclic beta-sheet-based peptides binding chemokines to specifically disrupt heteromers and we will generate mice with conditional deletion or knock-in of chemokine mutants with defects in heteromerization or proteoglycan binding to be analyzed in models of atherosclerosis. Peptides will be used for molecular imaging and chemokine heteromers will be quantified in cardiovascular patients.

Project Turbulent Transport in the Atmosphere: Fluctuations and Extreme Events
Researcher (PI) Jérémie Bec
Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Call Details Starting Grant (StG), PE3, ERC-2009-StG
Summary A major part of the physical and chemical processes occurring in the atmosphere involves the turbulent transport of tiny particles. Current studies and models use a formulation in terms of mean fields, where the strong variations in the dynamical and statistical properties of the particles are neglected and where the underlying fluctuations of the fluid flow velocity are oversimplified. Devising an accurate understanding of the influence of air turbulence and of the extreme fluctuations that it generates in the dispersed phase remains a challenging issue. This project aims at coordinating and integrating theoretical, numerical, experimental, and observational efforts to develop a new statistical understanding of the role of fluctuations in atmospheric transport processes. The proposed work will cover individual as well as collective behaviors and will provide a systematic and unified description of targeted specific processes involving suspended drops or particles: the dispersion of pollutants from a source, the growth by condensation and coagulation of droplets and ice crystals in clouds, the scavenging, settling and re-suspension of aerosols, and the radiative and climatic effects of particles. The proposed approach is based on the use of tools borrowed from statistical physics and field theory, and from the theory of large deviations and of random dynamical systems in order to design new observables that will be simultaneously tractable analytically in simplified models and of relevance for the quantitative handling of such physical mechanisms. One of the outcomes will be to provide a new framework for improving and refining the methods used in meteorology and atmospheric sciences and to answer the long-standing question of the effects of suspended particles onto climate.

Project From Attosecond Magnetism towards Ultrafast Spin Photonics
Researcher (PI) Jean-Yves Bigot
Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Call Details Advanced Grant (AdG), PE3, ERC-2009-AdG
Summary We propose to investigate a new frontier in Physics: the study of Magnetic systems using attosecond laser pulses. The main disciplines concerned are: Ultrafast laser sciences, Magnetism and Spin-Photonics, Relativistic Quantum Electrodynamics. Three issues of modern magnetism are addressed. 1. How fast can one modify and control the magnetization of a magnetic system ? 2. What is the role and essence of the coherent interaction between light and spins ? 3. How far spin-photonics can bring us to the real world of data acquisition and storage ? - We want first to provide solid ground experiments, unravelling the mechanisms involved in the demagnetization induced by laser pulses in a variety of magnetic materials (ferromagnetic nanostructures, aggregates and molecular magnets). We will explore the ultrafast magnetization dynamics of magnets using an attosecond laser source. - Second we want to explore how the photon field interacts with the spins. We will investigate the dynamical regime when the potential of the atoms is dressed by the Coulomb potential induced by the laser field. A strong support from the relativistic Quantum Electro-Dynamics is necessary towards that goal. - Third, even though our general approach is fundamental, we want to provide a benchmark of what is realistically possible in ultrafast spin-photonics, breaking the conventional thought that spin photonics is hard to implement at the application level. We will realize ultimate devices combining magneto-optical microscopy with the conventional magnetic recording. This new field will raise the interest of a number of competitive laboratories at the international level. Due to the overlapping disciplines the project also carries a large amount of educational impact both fundamental and applied.

Researcher (PI) Michael Karl Koehl
Host Institution (HI) RHEINISCHE FRIEDRICH-WILHELMS-UNIVERSITAT BONN
Call Details Starting Grant (StG), PE2, ERC-2009-StG
Summary We propose to investigate hybrid quantum systems composed of ultracold atoms and ions. The mutual interaction of the cold neutral atoms and the trapped ion offers a wealth of interesting new physical problems. They span from ultracold quantum chemistry over new concepts for quantum information processing to genuine quantum many-body physics. We plan to explore aspects of quantum chemistry with ultracold atoms and ions to obtain a full understanding of the interactions in this hybrid system. We will investigate the regime of low energy collisions and search for Feshbach resonances to tune the interaction strength between atoms and ions. Moreover, we will study collective effects in chemical reactions between a Bose-Einstein condensate and a single ion. Taking advantage of the extraordinary properties of the atom-ion mixture quantum information processing with hybrid systems will be performed. In particular, we plan to realize sympathetic ground state cooling of the ion with a Bose-Einstein condensate. When the ion is immersed into the ultracold neutral atom environment the nature of the decoherence will be tailored by tuning properties of the environment: A dissipative quantum phase transition is predicted when the ion is coupled to a one-dimensional Bose gas. Moreover, we plan to realize a scalable hybrid quantum processor composed of a single ion and an array of neutral atoms in an optical lattice. The third direction we will pursue is related to impurity effects in quantum many-body physics. We plan to study transport through a single impurity or atomic quantum dot with the goal of realizing a single atom transistor. A single atom transistor transfers the quantum state of the impurity coherently to a macroscopic neutral atom current. Finally, we plan to observe Anderson s orthogonality catastrophe in which the presence of a single impurity in a quantum gas orthogonalizes the quantum many-body function of a quantum state with respect to the unperturbed one.

Project acronym BABYLON
Project By the Rivers of Babylon: New Perspectives on Second Temple Judaism from Cuneiform Texts
Researcher (PI) Caroline Waerzeggers
Host Institution (HI) UNIVERSITEIT LEIDEN
Call Details Starting Grant (StG), SH6, ERC-2009-StG
Summary This project has the potential to radically change current understanding of cultic and social transformation in the post-exilic temple community of Jerusalem (c. 6th-4th centuries BCE), an important formative phase of ancient Judaism. “BABYLON” draws on recent, ground-breaking advances in the study of cuneiform texts to illuminate the Babylonian environment of the Judean exile, the socio-historical context which gave rise to the transformative era in Second Temple Judaism. In particular, these new data show that the parallels between Babylonian and post-exilic forms of cultic and social organization were substantially more far-reaching than presently recognized in Biblical scholarship. “BABYLON” will study the extent of these similarities and explore the question how Babylonian models could have influenced the restoration effort in Jerusalem.
This goal will be achieved through four sub-projects. P1 will study the social dynamics and intellectual universe of the Babylonian priesthood. P2 will finalize the publication of cuneiform archives of Babylonian priests living in the time of the exile. P3 will identify the exact areas of change in the post-exilic temple community of Jerusalem. P4, the synthesis, will draw from each of these sub-projects to present a comparative study of the Second Temple and contemporary Babylonian models of cultic and social organization, and to propose a strategy of research into the possible routes of transmission between Babylonia and Jerusalem.
The research will be carried out by three team members: the PI (P1 and P4), a PhD in Assyriology (P2) and a post-doctoral researcher in Biblical Studies specialized in the Second Temple period (P3 and P4). The participation of the wider academic community will be invited at two moments in the course of the project, in the form of a workshop and an international conference.
“BABYLON” will adopt an interdisciplinary approach by bringing together Assyriologists and Biblical scholars for a much-needed dialogue, thereby exploding the artificial boundaries that currently exist in the academic landscape between these two fields.

Host Institution (HI) EIDGENOESSISCHE TECHNISCHE HOCHSCHULE ZUERICH
Call Details Advanced Grant (AdG), LS3, ERC-2009-AdG
Summary Asymmetric cell division is a key mechanism for the generation of cell diversity in eukaryotes. During this process, a polarized mother cell divides into non-equivalent daughters. These may differentially inherit fate determinants, irreparable damages or age determinants. Our aim is to decipher the mechanisms governing the individualization of daughters from each other. In the past ten years, our studies identified several lateral diffusion barriers located in the plasma membrane and the endoplasmic reticulum of budding yeast. These barriers all restrict molecular exchanges between the mother cell and its bud, and thereby compartmentalize the cell already long before its division. They play key roles in the asymmetric segregation of various factors. On one side, they help maintain polarized factors into the bud. Thereby, they reinforce cell polarity and sequester daughter-specific fate determinants into the bud. On the other side they prevent aging factors of the mother from entering the bud. Hence, they play key roles in the rejuvenation of the bud, in the aging of the mother, and in the differentiation of mother and daughter from each other. Recently, we accumulated evidence that some of these barriers are subject to regulation, such as to help modulate the longevity of the mother cell in response to environmental signals. Our data also suggest that barriers help the mother cell keep traces of its life history, thereby contributing to its individuation and adaption to the environment. In this project, we will address the following questions: 1 How are these barriers assembled, functioning, and regulated? 2 What type of differentiation processes are they involved in? 3 Are they conserved in other eukaryotes, and what are their functions outside of budding yeast? These studies will shed light into the principles underlying and linking aging, rejuvenation and differentiation.

Project Bosnian Bones, Spanish Ghosts: 'Transitional Justice' and the Legal Shaping of Memory after Two Modern Conflicts
Researcher (PI) Sarah Lynn Wastell (Born Haller)
Host Institution (HI) GOLDSMITHS' COLLEGE
Call Details Starting Grant (StG), SH2, ERC-2009-StG
Summary The proposed research entails an ethnographic study of two contemporary cases of post-conflict reconciliation: one, the Bosnian case, where international intervention ended conflict in a stalemate and went on to instigate a decade-long process of transition; and the other, the Spanish case, where a nationally-contrived pact of silence introduced an overnight transition after Franco's death a pact now being broken nearly seventy years after the country's civil war concluded. Both societies witnessed massive violations of international humanitarian law. Both societies are presently exhuming, identifying and re-burying their dead. But their trajectories of transitional justice could not have been more different. This project will investigate how Law shapes cultural memories of wartime atrocity in these contrasting scenarios. How do criminal prosecutions, constitutional reforms, and international rights mechanisms, provide or obfuscate the scales into which histories of violent conflict are framed? Does the systematic re-structuring of legislative and judicial infrastructure stifle recognition of past abuses or does it create the conditions through which such pasts can be confronted? How does Law shape or inflect the cultural politics of memory and memorialisation? And most importantly, how should legal activity be weighted, prioritised and sequenced with other, extra-legal components of peace-building initiatives? The ultimate goal of this project will be to mobilise the findings from the two field-sites to suggest a more nuanced assessment of Law s place in transitional justice. Arguing that disparate historical, cultural and legal contexts require equally distinct approaches towards social healing, the research aims to produce a Post-Conflict Action Framework an architecture of questions and concerns, which, once answered, would point towards context-specific designs for transitional justice programmes in the future.

Project Towards a comparative sociology of beauty The transnational modelling industry and the social shaping of beauty standards in six European countries
Researcher (PI) Giselinde Maniouschka Marije Kuipers
Host Institution (HI) UNIVERSITEIT VAN AMSTERDAM
Call Details Starting Grant (StG), SH2, ERC-2009-StG
Summary This project studies how beauty standards - perceptions of physical beauty in women and men - are socially shaped. It will focus on the transnational modelling industry, an institution centrally concerned with the production and dissemination of beauty standards. The project aims to develop a comparative sociology of beauty. By comparing beauty standards both within and across nations, it will identify central mechanisms and institutions through which such standards are developed and disseminated. In 4 subprojects this study investigates 1. How standards of female and male beauty are perceived, shaped, and disseminated by professionals in the transnational modelling field; 2. How female and male models perceive, represent and embody beauty standards in their work; 3. How female and male beauty has been portrayed by models in mainstream and high fashion magazines from 1980 till 2010; 4. How people of different backgrounds perceive female and male beauty, and how their beauty standards are related to the images disseminated in modelling. Each project will be done in France, Italy, the Netherlands, Poland, Turkey and the UK. This project is innovative in several ways. It is the first comprehensive study of the social shaping of beauty standards. The 4 subprojects will result in an extensive account of production, products, and reception of a contested cultural industry. Moreover, this project draws together in novel ways theories about media, cultural production and taste formation; gender and the body; and globalization. The project will make a major contribution to the study of globalization: it studies a transnational cultural industry, and its comparative and longitudinal design allows us to gauge the impact of globalization in different contexts. Finally, the project is innovative in its comparative, multi-method research design, in which the subprojects will follow the entire process of production and consumption in a transnational field.

The project will make a major contribution to the study of globalization: it studies a transnational cultural industry, and its comparative and longitudinal design allows us to gauge the impact of globalization in different contexts. Finally, the project is innovative in its comparative, multi-method research design, in which the subprojects will follow the entire process of production and consumption in a transnational field.
