Call Details Advanced Grant (AdG), PE3, ERC-2010-AdG_20100224
Summary The 0MSPIN project consists of an extensive integrated theoretical, experimental and device development programme of research opening a radical new approach to spintronics. Spintronics has the potential to supersede existing storage and memory applications, and to provide alternatives to current CMOS technology. Ferromagnetic matels used in all current spintronics applications may make it impractical to realise the full potential of spintronics. Metals are unsuitable for transistor and information processing applications, for opto-electronics, or for high-density integration. The 0MSPIN project aims to remove the major road-block holding back the development of spintronics in a radical way: removing the ferromagnetic component from key active parts or from the whole of the spintronic devices. This approach is based on exploiting the combination of exchange and spin-orbit coupling phenomena and material systems with zero macroscopic moment. The goal of the 0MSPIN is to provide a new paradigm by which spintronics can enter the realms of conventional semiconductors in both fundamental condensed matter research and in information technologies. In the central part of the proposal, the research towards this goal is embedded within a materials science project whose aim is to introduce into physics and microelectronics an entirely new class of semiconductors. 0MSPIN seeks to exploit three classes of material systems: (1) Antiferromagnetic bi-metallic 3d-5d alloys (e.g. Mn2Au). (2) Antiferromagnetic I-II-V semiconductors (e.g. LiMnAs). (3) Non-magnetic spin-orbit coupled semiconductors with injected spin-polarized currents (e.g. 2D III-V structures). Proof of concept devices operating at high temperatures will be fabricated to show-case new functionalities offered by zero-moment systems for sensing and memory applications, information processing, and opto-electronics technologies.

Project Continuity and Rupture in Central European Art and Architecture, 1918-1939
Researcher (PI) Matthew RAMPLEY
Host Institution (HI) Masarykova univerzita
Call Details Advanced Grant (AdG), SH5, ERC-2017-ADG
Summary When new political elites and social structures emerge out of a historical rupture, how are art and architecture affected? In 1918 the political map of central Europe was redrawn as a result of the collapse of Austria-Hungary, marking a new era for the region. Through comparative analysis of the visual arts in 3 states built on the ruins of the Habsburg Empire (Austria, Hungary and [former] Czechoslovakia), this project examines how such political discontinuity affected art and architecture between 1918 and 1939. The project is organised into 4 themes, each resulting in a monograph:
1. Vernacular modernisms, nostalgia and the avant-garde
2. Presenting the state: world fairs and exhibitionary cultures
3. Piety, reaction and renewal
4. Contested histories: monuments, memory and representations of the historical past
It is the first systematic and comprehensive trans-national study of this type, based on the claim that the successor states to Austria-Hungary belonged to a common cultural space informed by the shared memory of the long years of Habsburg society and culture. The project focuses on the contradictory ways that visual arts of artists and architects in central Europe adapted to and tried to shape new socio-political circumstances in the light of the past. The project thus examines the long shadow of the Habsburg Empire over the art and culture of the twentieth century.
The project also considers the impact of the political and ideological imperatives of the three successor states on the visual arts; how did governments treat the past? Did they encourage a sense of historical caesura or look to the past for legitimation? How did artists and architects respond to such new impulses? In answering these questions the project analyses the conflicts between avant-gardes and more conservative artistic movements; the role of the visual arts in interwar memory politics; the place of art in the nexus of religion, national and state identity.

Researcher (PI) Josef Michl
Host Institution (HI) USTAV ORGANICKE CHEMIE A BIOCHEMIE, AV CR, V.V.I.
Call Details Advanced Grant (AdG), PE5, ERC-2008-AdG
Summary We propose a feasibility demonstration of an unprecedented concept: preparation of regular two-dimensional arrays of artificial surface-mounted dipolar molecular rotors and control of their coherent motion by the application of an outside electric field. The proposal involves a highly interdisciplinary endeavor, which requires experience in synthesis (preparation of molecular rotors), surface chemistry (assembly of rotors into arrays on surfaces), surface spectroscopy and scanning microscopy (characterization of rotor arrays on surfaces), and theory (modeling of rotor dynamics). The principal investigator is presently actively working and publishing in all of these subdisciplines.

Project Ecological determinants of tropical-temperate trends in insect diversity
Researcher (PI) Vojtech Novotny
Host Institution (HI) Biologicke centrum AV CR, v. v. i.
Call Details Advanced Grant (AdG), LS8, ERC-2014-ADG
Summary The study will examine one of the most fundamental, yet poorly understood patterns of global biodiversity distribution: How can so many species coexist in a tropical forest? This key question of current ecology will be studied using quantitative surveys of plant-herbivore-parasitoid food webs within paired sets of tropical and temperate forests from six continents, in Papua New Guinea (PNG), Gabon, Panama, the Czech Republic, Japan, and USA, sampled using canopy cranes, truck-mounted elevated platforms and forest felling. This novel type of data will be analysed using a new rarefaction method, developed to test mechanistic explanations for biodiversity patterns along ecological gradients. It will evaluate competing hypotheses explaining latitudinal trends in insect herbivore diversity by the variation in either phylogenetic or functional diversity of plants, the host specificity of herbivores, or the diversity and specificity of their parasitoids and predators. The study will thus examine the importance of bottom-up (plants) and top-down (enemies) drivers of latitudinal trends in herbivore food webs, central to ecological theory that postulates the role of specialized herbivores as density-dependent agents of mortality involved in maintaining high tropical plant diversity. The project builds upon prior research that produced one of the largest tropical food web data sets to expand it conceptually, methodologically and geographically. It will build a globally important research facility (a canopy crane in PNG) and link researchers and infrastructure from several countries in a major effort to draw together separate lines of tropical and temperate research. Study sites in the ILTER, NEON, CTFS/SIGEO, and Canopy Crane Network will participate. The internationally recognized paraecologist program will be expanded, PhD students from both European and developing countries will be trained, and conservation of rainforests by indigenous rainforest dwellers will be leveraged.

Project acronym ELE
Project Evolving Language Ecosystems
Researcher (PI) Jan VITEK
Host Institution (HI) CESKE VYSOKE UCENI TECHNICKE V PRAZE
Call Details Advanced Grant (AdG), PE6, ERC-2015-AdG
Summary The ELE project will study the foundational principles of programming language evolution and develop practical tools and technologies for supporting the evolution of complete ecosystems. If successful, ELE will drastically decrease the cost of evolution and avoid the need to invent completely new languages every time there is a shift in hardware trends or in programming methodology. Instead, ELE will allow evolution of languages and will support migration of code and knowledge bases. The project proceeds along two major axes. The first axis is language dynamics where new features and new capabilities are added to a preexisting language. This requires changing, at the same time, the language's specification, it's semantics, and the language's implementation, the compiler and interpreter that runs code written in the language as well the runtime libraries that provide basic capabilities. The second axis for evolution is language statics where new rules are added to enforce novel programming disciplines and where existing code artifacts are adapted to new semantics. These axes are not entirely disjoint, as static restrictions, such as a new type system, can feedback into the implementation by providing behavioral information that can be exploited by a compiler.

Project "Feasibility, logic and randomness in computational complexity"
Researcher (PI) Pavel Pudlák
Host Institution (HI) MATEMATICKY USTAV AV CR V.V.I.
Call Details Advanced Grant (AdG), PE6, ERC-2013-ADG
Summary "We will study fundamental problems in complexity theory using means developed in logic, specifically, in the filed of proof complexity. Since these problems seem extremely difficult and little progress has been achieved in solving them, we will prove results that will explain why they are so difficult and in which direction theory should be developed.
Our aim is to develop a system of conjectures based on the concepts of feasible incompleteness and pseudorandomness. Feasible incompleteness refers to conjectures about unprovability of statements concerning low complexity computations and about lengths of proofs of finite consistency statements. Essentially, they say that incompleteness in the finite domain behaves in a similar way as in the infinite. Several conjectures of this kind have been already stated. They have strong consequences concerning separation of complexity classes, but only a few special cases have been proved. We want to develop a unified system which will also include conjectures connecting feasible incompleteness with pseudorandomness. A major part of our work will concern proving special cases and relativized versions of these conjectures in order to provide evidence for their truth. We believe that the essence of the fundamental problems in complexity theory is logical, and thus developing theory in the way described above will eventually lead to their solution."

Host Institution (HI) USTAV ORGANICKE CHEMIE A BIOCHEMIE, AV CR, V.V.I.
Call Details Advanced Grant (AdG), PE4, ERC-2008-AdG
Summary This project of basic research in chemistry tackles the challenge to close the wide gap between chemical and physical processes occurring in liquid solution and sophisticated studies of model systems in the idealized gas phase. By such the project aims to reach a convergence between the microscopic and macroscopic world. To this end, the planned research will span the range from isolated atoms in the high vacuum to the real species present in solution. Specifically, the proposal is focused on:
- Ion solvation in dipolar media (e.g. aqueous salt solutions)
- Influence of sequential solvation on redox processes (relevant in corrosion, for example)
- Mechanisms by which metal catalysts facilitate chemical reactions (e.g. polymerizations)
In order to address these tasks, the PI will combine his profound expertise in gas-phase methods with well-established techniques from solution chemistry for the development of new and innovative coupling techniques which will allow to derive direct correlations between micro- and macroscopic properties. A particular highlight is the planned online-coupling of electron paramagnetic resonance (EPR) with electrospray ionization (ESI) mass spectrometry, which is unique worldwide and offers the exploration of new dimensions for both, EPR methods and ESI mass spectrometry.
While the project is located in chemical sciences, physical-organic chemistry in particular, the prospects of the proposal range not only far beyond the PI's specific field of specialization into other areas of chemistry, but due to the enormous relevance of ion solvation, redox processes, and catalysis also into biological, physical and geological sciences with implications up to our daily life.
The PI has excellent publication records with >330 scientific papers, >7800 citations, and a Hirsch-Index of 44. Despite several risks along the way, the expertise of the PI thus warrants a successful realization of this challenging project.

Call Details Advanced Grant (AdG), PE1, ERC-2012-ADG_20120216
Summary "The main goal of the present research proposal is to build up a general mathematical theory describing the motion of a compressible, viscous, and heat conductive fluid. Our approach is based on the concept of generalized (weak) solutions satisfying the basic physical principles of balance of mass, momentum, and energy. The energy balance is expressed in terms of a variant of entropy inequality supplemented with an integral identity for the total energy balance.
We propose to identify a class of suitable weak solutions, where admissibility is based on a direct application of the principle of maximal entropy production compatible with Second law of thermodynamics. Stability of the solution family will be investigated by the method of relative entropies constructed on the basis of certain thermodynamics potentials as ballistic free energy.
The new solution framework will be applied to multiscale problems, where several characteristic scales become small or extremely large. We focus on mutual interaction of scales during this process and identify the asymptotic behavior of the quantities that are filtered out in the singular limits. We also propose to study the influence of the geometry of the underlying physical space that may change in the course of the limit process. In particular, problems arising in homogenization and optimal shape design in combination with various singular limits are taken into account.
The abstract approximate scheme used in the existence theory will be adapted in order to develop adequate numerical methods. We study stability and convergence of these methods using the tools developed in the abstract part, in particular, the relative entropies."
