Host Institution (HI) AALTO KORKEAKOULUSAATIO SR
Call Details Proof of Concept (PoC), ERC-2018-PoC
Summary Downscaling of Si-based microprocessors has considerably increased the amount of heating in computers and other information and communication technology (ICT) devices. As a result, computer servers in big data centres waste more than 90% of the electricity they pull off the grid. High-density electrical currents in microprocessors and interconnects cause excessive warm-up via an effect known as Joule heating. To fulfil future requirements for data transmission and processing rates with low energy consumption, a paradigm shift away from purely charge-based electronics is needed. Recently, post-Si computing with collective spin wave excitations in tailored magnets has been identified as a promising route. Spin waves are transmitted through a magnetic material without the displacement of electric charges (i.e. currents), thus drastically reducing energy consumption and heating. We recently demonstrated that short-wavelength spin waves can be emitted and manipulated by small voltage pulses in ferroelectric-ferromagnetic bilayers. In the ERC PoC project we will use our results to realise an industrially relevant integrated spin wave computing device.

Project Preservation and Efficacy of Music and Singing in Ageing, Aphasia, and Alzheimer’s Disease

Summary For the human brain, music is a highly complex and versatile stimulus that is closely linked to speech, executive-motor, emotion, and memory networks. In severe ageing-related neurological disorders, such as post-stroke aphasia and Alzheimer’s disease (AD) dementia, music and singing may provide a valuable alternative route to verbal and emotional expression and to memory and self-awareness. However, the neural processes underlying this are still poorly understood. Moreover, although there is increasing evidence for the efficacy of musical activities in supporting normal neurocognitive ageing and enhancing neurological recovery, the focus has been on individual-level musical activities, overlooking the enormous social potential of music.
PREMUS will combine modern behavioural and neuroimaging methods in the unique context of cross-sectional and cohort studies and clinical trials to achieve both fundamental and applied research goals. The fundamental goal of PREMUS is to determine the neural basis of singing, music-evoked emotions and memories, and explicit and implicit musical learning (i) across normal ageing, (ii) in aphasia, and (iii) in different stages of AD. The applied goal of PREMUS is to uncover the rehabilitative potential of social musical activities by (iv) exploring the long-term efficacy of choir singing on neurocognitive, emotional, and social functioning in normal ageing and mild cognitive impairment and (v) determining the rehabilitative efficacy of a novel intervention that utilizes adapted choir singing, melodic intonation therapy, and computer-based singing training on verbal, cognitive, emotional, and social functioning in aphasia, together with uncovering the structural and functional neuroplasticity changes underlying the effects of the singing interventions. The outcome of PREMUS will have major scientific, clinical, and societal value as well as enormous practical impact on promoting healthy ageing, aphasia rehabilitation, and dementia care

Project Photonic Structural Materials with Controlled Disorder
Researcher (PI) Ullrich STEINER
Host Institution (HI) UNIVERSITE DE FRIBOURG
Call Details Advanced Grant (AdG), PE3, ERC-2018-ADG
Summary "Structural colour reflected by photonic materials is typically attributed to highly ordered nanostructures with periodicities on the 100-nm length scale. When investigating structural colour in animals and plants, it is however becoming increasingly evident that brilliant photonic colour can also arise from seemingly disordered morphologies. This is surprising as uncontrolled disorder in photonic materials usually severely degrades their colour response. While some recent theories exist, the emergence of structural colour from disordered morphologies is fundamentally not understood. It is clear however that these disordered morphologies must possess ""hidden correlations"", which enable the formation of a photonic band gap.
This project will uncover the design rules that underlie disordered photonic morphologies, thereby contributing to the fundamental understanding of photonic materials. The project has a strong nature-inspired component, but will go beyond the examination of natural photonic materials. WP1 and WP2 will examine 3D and 2D disordered photonic morphologies in animals and plants, respectively. The structural analysis of these materials will uncover hidden correlations in seemingly random morphologies. WP2 and WP3 will manufacture materials that implement these correlations to recreate the optical signatures of the biological model organisms. This will test the statistical analysis of WP1 and WP2 and shed light on the \textit{in vivo} synthesis of the disordered photonic morphologies. WP4 ties WP1-WP3 together by performing optical experiments and computer simulations. By analysing both the far- and near-field results of the simulations and comparing them with the structural correlations and optical experiments, the four WPs will not only provide a fundamental understanding of the interplay of structural correlations with optical interference in disordered materials, it will also establish design rules allowing their facile manufacture."

Host Institution (HI) ECOLE POLYTECHNIQUE FEDERALE DE LAUSANNE
Call Details Consolidator Grant (CoG), PE4, ERC-2018-COG
Summary This project exploits the synergy between the trending area of artificial molecular machines and cutting edge computational chemistry approaches. Specific emphasis is placed on photoswitchable catalysts, which respond to external stimuli with a conformational or configurational change. These controllable motions allow catalytic function to be turned ON/OFF in a switch type fashion by opening/hindering access of a substrate to a catalytic site. On one hand, the rich morphology and chemistry of these smart catalysts calls for computational insights and design principles that complement experiment and push the field forward. On the other hand, the inherent complexity of these highly fluxional molecules makes them perfect subjects for driving modern quantum chemistry out of its comfort zone. To benefit from this synergy, the latest innovations in quantum chemistry-based machine learning techniques will be combined with methods capable of thoroughly mapping the intricate chemistry of molecular actuators. Overall, we aim to bridge the gap between the current state-of-the-art, which has reached reasonable quantum chemical accuracy for rigid medium size organic molecules, and more challenging fluxional architectures. The proposed methodological toolbox will be applied to the field of smart catalysis where general strategies for improving the efficiencies and enhancing enantioselectivity will be formulated. Thus, this project involves exploiting a wide range of modern computational approaches to chemical tasks that are broadly relevant to flexible/switchable catalytic systems. The anticipated output will furnish the computational chemistry community with a comprehensive array of novel next-generation approaches with applicability beyond the field of molecular machines.

Project Quantitative stochastic homogenization of variational problems
Researcher (PI) Tuomo Kuusi
Host Institution (HI) HELSINGIN YLIOPISTO
Call Details Consolidator Grant (CoG), PE1, ERC-2018-COG
Summary The proposal addresses various multiscale problems which lie at the intersection of probability theory and the analysis of partial differential equations and calculus of variations. Most of the proposed problems fit under the framework of stochastic homogenization, that is, the study of large-scale statistical properties of solutions to equations with random coefficients. In the last ten years, there has been significant progress made in developing a quantitative theory of stochastic homogenization, meaning that one can now go beyond limit theorems and prove rates of convergence and error estimates, and in some cases even characterize the fluctuations of the error. These new quantitative methods give us new tools to attack more difficult multi-scale problems that have until now resisted previous approaches, and consequently to solve open problems in the field.
Many of the actual goals of the proposal come from problems in calculus of variations. Apart from qualitative results, many fundamental questions in quantitative theory are completely open, and our recent results suggest a way to tackle these problems. The first one is to prove regularity properties of homogenized Lagrangian under rather general assumptions on functionals, and to solve a counterpart for Hilbert's 19th problem in the context of homogenization. The second project is to attack so-called Faber-Krahn inequality in the heterogeneous case. This is a very involved problem, but again recent development in the theory of homogenization makes the attempt plausible. The final part of the proposal involves new mathematical approaches and subsequent computational research supporting the geothermal power plant project being built by St1 Deep Heat Ltd in Espoo, Finland.

Summary QTONE aims at discovering new quantum phenomena involving THz vibrational modes, and at gaining control over them using novel concepts inspired from cavity quantum optomechanics and new techniques developed for nano-plasmonics and molecular break-junctions. The three main goals of the project are:
(i) Perform optomechanical quantum information processing with THz phonons in low-dimensional systems, using a combination of ultrafast spectroscopy and time-correlated photon counting to measure quantum correlations mediated by non-classical vibrational states.
(ii) Demonstrate the feasibility of dynamical backaction amplification of THz phonons by coupling molecules and nanomaterials to plasmonic cavities and by leveraging exciton-phonon coupling to realize exciton-assisted optomechanics.
(iii) Interrogate and drive a single-molecule inside a plasmonic nanocavity using simultaneous inelastic electron tunneling and Raman spectroscopies in a molecular break-junction with engineered plasmonic resonance.
I anticipate that this project will have widespread impacts on our understanding of quantum phenomena in molecular-scale oscillators, and will foster the excellence of Europe in fields ranging from fundamental science to quantum technologies and molecular electronics.

Summary The use of delicate quasiconformal methods, in conjunction with convex integration and/or nonlinear Fourier analysis, will be the common theme of the proposal.

First and foremost, Morrey's fundamental question in two dimensional vectorial calculus of variations will be considered as well as the related conjecture of Iwaniec regarding the sharp $L^p$ bounds for the Beurling transform. Understanding the geometry of conformally invariant random structures will be one of the central goals of the proposal. Uhlmann's conjecture regarding the optimal regularity for uniqueness in Calder\'on's inverse conductivity problem will also be considered, as well as the applications to imaging. Further goals are to be found in fluid mechanics and scattering, as well as the fundamental properties of quasiconformal mappings, interesting in their own right, such as the outstanding deformation problem for chord-arc curves.

Researcher (PI) Rainer Andreas KRAUSE
Host Institution (HI) EIDGENOESSISCHE TECHNISCHE HOCHSCHULE ZUERICH
Call Details Consolidator Grant (CoG), PE6, ERC-2018-COG
Summary This ERC project pushes the boundary of reliable data-driven decision making in cyber-physical systems (CPS), by bridging reinforcement learning (RL), nonparametric estimation and robust optimization. RL is a powerful abstraction of decision making under uncertainty and has witnessed dramatic recent breakthroughs. Most of these successes have been in games such as Go - well specified, closed environments that - given enough computing power - can be extensively simulated and explored. In real-world CPS, however, accurate simulations are rarely available, and exploration in these applications is a highly dangerous proposition.
We strive to rethink Reinforcement Learning from the perspective of reliability and robustness required by real-world applications. We build on our recent breakthrough result on safe Bayesian optimization (SAFE-OPT): The approach allows - for the first time - to identify provably near-optimal policies in episodic RL tasks, while guaranteeing under some regularity assumptions that with high probability no unsafe states are visited - even if the set of safe parameter values is a priori unknown.
While extremely promising, this result has several fundamental limitations, which we seek to overcome in this ERC project. To this end we will (1) go beyond low-dimensional Gaussian process models and towards much richer deep Bayesian models; (2) go beyond episodic tasks, by explicitly reasoning about the dynamics and employing ideas from robust control theory and (3) tackle bootstrapping of safe initial policies by bridging simulations and real-world experiments via multi-fidelity Bayesian optimization, and by pursuing safe active imitation learning.
Our research is motivated by three real-world CPS applications, which we pursue in interdisciplinary collaboration: Safe exploration of and with robotic platforms; tuning the energy efficiency of photovoltaic powerplants and safely optimizing the performance of a Free Electron Laser.

Project Targeting pathological synaptic pruning by microglia in neurodegeneration
Researcher (PI) Rosa Chiara Immacolata PAOLICELLI
Host Institution (HI) UNIVERSITE DE LAUSANNE
Call Details Starting Grant (StG), LS5, ERC-2018-STG
Summary Synapse loss is the major correlate of cognitive impairment in many neurodegenerative diseases. Recent literature suggests that microglia, which mediate synaptic pruning during brain development, can be responsible for synapse loss in neurodegeneration. Although the underlying mechanisms are poorly understood, growing evidence indicates that dysfunctional microglia affect synapses number and function in pathology. Genome-wide association studies reveal that the majority of risk genes associated with neurodegenerative disorders are highly expressed in microglia. While such studies clearly implicate these cells in the pathogenesis of the disease, little is known about the causal mechanisms that link microglial risk variants to loss of synapses.
We will identify the molecular mechanisms involved in microglia-mediated synapse loss. We will also generate novel in vitro and ex vivo models of ‘risk microglia’, by introducing genetic variants associated with cognitive impairment –alone or in combination- specifically in microglia, taking advantage of CRISPR/ Cas9 genome editing techniques. These goals will be achieved by combining cutting-edge transcriptomics and proteomics with mouse models of intense synaptic remodelling, to reveal the unique molecular signature of ‘shaper microglia’. A multidisciplinary approach will allow the extensive characterisation of risk models, by combining metabolic analysis, synaptic phagocytosis and degradation assays, with super-resolution microscopy, and novel genetically encoded labelling methods. With the knowledge generated here, we aim at developing and validating in vivo novel drugs- and nanobodies-based approaches for effective targeting of pathological pruning.
In summary, REMIND will focus on:
1) Identifying molecular players in microglial-mediated synapse loss
2) Generating ‘risk microglia’ models, to asses the role of genetic variants associated with neurodegeneration
3) Developing novel strategies for targeting prunining

Summary SCALE-HALO proposes a research program that will advance the development of highly luminescent molecular and solid-state compounds by focusing on the emerging, vast, and rather underexplored compositional and structural spaces comprised of metals and halogens, i.e., metal halides (MHs). SCALE-HALO is motivated by the eventual utility of MHs as versatile photonic sources in modern appliances (e.g., displays and lighting) and in future quantum technologies. The recent success of lead halide perovskites in optoelectronics inspires broader exploration of the chemistry and photophysics of MHs. The clear objective is to determine factors controlling the spectral widths and emission peak wavelengths, Stokes shifts, radiative lifetimes, and quantum efficiencies. In addition to the need to discover new chemically robust and nontoxic MH emitters, there is also a critical need to engineer material morphologies suitable for specific applications (e.g., thin films, nanocrystals, composites, etc.) Ensuring the thermal and environmental stabilities are especially important efforts. SCALE-HALO will therefore encompass the chemical engineering of MHs at the atomic scale (e.g., new compounds), nanoscale (e.g., synthesis of nanostructures and their surface chemistry), and mesoscale (e.g., nanostructure superlattices and composites). Furthermore, modern exploratory syntheses will be accelerated with automated high-throughput methods (e.g., robotics and microfluidics). The characterization toolbox for probing the local atomistic structure will be expanded with multinuclear NMR spectroscopy. The individual and collective optical properties of MH nanostructures and their periodic assemblies will be established and rationalized. Toward diverse real-world applications, first trials will be undertaken to evaluate the potentials of novel MH materials for LCD displays, solid-state lighting and light-emitting diodes.
