Projet NIT-NL (Horizon Europe, appel à projets 2022)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Information Science and Engineering
Statut du projet : CLOSED

Optical fiber systems carry nearly all of the global Internet traffic and are critical infrastructure for modern society. Long-haul optical networks are often based on the notion of wavelength division multiplexing (WDM). At high signal intensities, WDM systems are impaired by the inherent nonlinear effects involved in fiber propagation. In the literature, the fundamental limits of WDM transmission are investigated using information theory. The prevalent viewpoint only focuses on achievable rates for individual users under different behavioral assumptions for the interfering users. NIT-NL deviates significantly from this single-user viewpoint and proposes a multi-user information theoretic approach for the WDM channel that investigates the region of simultaneously achievable rates for all the different users. NIT-NL aims to exploit this holistic perspective and realize a more efficient utilization of the optical network resources. This will be achieved via a) characterization of closed form inner and outer bounds to the capacity region based on realistic channel models, b) asymptotic analyses in the limit of high transmit power to infer the nature of optimal strategies in the highly nonlinear regime, and c) derivation of optimality conditions for simple and practical schemes such as treating interference as noise to achieve the sum-capacity of the given model. NIT-NL will have a direct impact on the scientific community engaged in the long-standing quest of dealing with nonlinear impairments in optical channels, and the multi-user information theory community that will welcome its enrichment on nonlinear channel models. It will also benefit the European telecommunications industry and standardization initiatives.

Projet QOMBE (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Physics
Statut du projet : SIGNED

Quantum simulation is a fundamental concept in our pre-fault tolerant era. In this respect, waveguide quantum electrodynamics (wQED) setups, i.e., quantum emitters (atoms) interfaced with engineered photonic materials, represent promising NISQ devices for analog quantum simulation. Many experimental platforms to engineer photonic environments, e.g., arrays of superconducting circuits, possess intrinsic photonic nonlinearities in the form of photon-photon interactions caused by, e.g., the anharmonicity of the superconducting circuits. Though available for specific cases, a coherent theoretical framework to describe nonlinear many-body wQED systems is still missing. The nonlinear character of a photonic bath renders the whole system complex and not exactly solvable, making standard quantum optics textbook approaches not applicable. This project will introduce a radically new approach to this field by transferring knowledge from quantum field theory (QFT) to wQED, an approach that has already proven useful in condensed matter and in ultracold atoms physics. We will study nonlinear wQED systems, i.e., with photon-photon interactions, modelled by, e.g., a Bose-Hubbard Hamiltonian, and investigate purely photonic many-body physics effects like quantum phase transitions. This will be carried out by developing a field theory for wQED using a path integral approach, of the most powerful tools in QFT to deal with interacting fields. The central goal will be derivation of an effective emitters’ action, which can probe the many-body physics of the photonic environment. In particular, we will be able to characterize the behavior of an atomic quantum simulator across a quantum phase transition of the surrounding photonic environment. Characterizing the effects of nonlinearities represents a breakthrough in the physics of wQED, and will shed light on how to harness these experimentally unavoidable features for optical quantum computing tasks.

Projet REGEN-PE (Horizon Europe, appel à projets 2023)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Information Science and Engineering
Statut du projet : CLOSED

REGEN-PE is driven by the vision to revolutionize power electronics by developing high-quality YAlN layers that not only enable affordable ultra-efficient performance but also promote sustainability through recycling. To achieve this ambitious goal, we adopt an ambitious approach that combines material density functional theory (DFT) simulations, sputtering and MOCVD for epitaxy, along with chemical and optical characterization techniques for material development. The project includes the successful integration of YAlN into cutting-edge electronic device structures, projected to surpass the GaN performance limit, which requires their design, fabrication, and electrical characterization. However, what sets the REGEN-PE project apart is its unwavering commitment to sustainability. By developing a novel method for material recovery, we aim to establish a precedent for recyclable semiconductor technology. REGEN-PE promotes a circular engineering approach, which sets the stage for the future of high-performance green power electronics.

Projet ROOMMATE (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Social Sciences and Humanities
Statut du projet : SIGNED

ROOMMATE investigates the increasingly prevalent phenomenon of prolonged involuntary house sharing within the private rental market among individuals aged 40+, using Amsterdam and Barcelona as case studies. Economic instability, demographic changes, and a shrinking pool of affordable housing are pushing mature tenants into shared accommodations.This project addresses a critical gap in housing research by shifting the focus from young adults to older individuals, thereby offering new empirical insights into how age intersects with housing insecurity. By employing a comparative urban approach and qualitative research, the project integrates life course perspectives with intersectional analysis to investigate how lived experiences of extended house sharing reshape notions of future and progress, alter reproductive decisions and caregiving practices, and exacerbate intersectional inequalities. These unique empirical insights will be used to explore innovative housing solutions addressing evolving social needs over the life course. The project aims to 1) establish a research framework to analyse long-term housing precarity; 2) empirically explore the lived experiences of older house sharers; and 3) examine international housing innovations to co-develop policies that address evolving life-course needs and enhance housing security for diverse populations. ROOMMATE's findings are expected to contribute significantly to the development of innovative policies and housing solutions, addressing urgent social challenges in Europe, such as prolonged precarity, demographic ageing, and the care and climate crises. By disseminating successful experiences in housing innovations and developing policies that support housing as a social infrastructure for diverse family choices, household configurations, care needs, and environmental challenges, ROOMMATE will significantly impact housing research and policy, promoting transformative improvements in housing equity and sustainability.

Projet microFFTTO (Horizon Europe, appel à projets 2022)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Information Science and Engineering
Statut du projet : SIGNED

Exploiting the full potential of additive manufacturing methods requires a leap forward in advanced modelling and computing techniques. While additive manufacturing enables the high-precision fabrication of architectured mechanical (meta)materials, its design is currently driven by human experience. As such, it could greatly benefit from numerical Topology Optimisation (TO) techniques. The µFFTTO project addresses two challenges of in-silico design of high-resolution architectured microstructures. First, state-of-the-art finite element computational homogenisation approaches, even when accelerated with highly efficient Fast Fourier Transform (FFT) techniques, are too costly for microstructures discretised into billions of voxels. I will significantly reduce their cost by developing a novel mesh coarsening technique based on low-rank tensor approximations. Second, as the manufacturing resolutions reach micrometre accuracy and the surface-to-volume ratio increases, surface effects, including adhesive contact, need to be accounted for in the TO formulations. This project will incorporate adhesive interaction into the low-rank FFT-based computational homogenisation scheme. As a result, the µFFTTO project will deliver computationally and memory affordable algorithms for microstructure TO on regular grids, which account for internal contacts with adhesion and are directly transferable to contemporary fabrication techniques. The project will be conducted in cooperation with leading experts on multiscale modelling and additive manufacturing from the livMatS Cluster of Excellence, University of Freiburg, Germany, with an emphasis on future collaboration with and knowledge transfer to the Czech Republic and Slovakia.

Projet CCSuperClock (Horizon Europe, appel à projets 2023)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Physics
Statut du projet : SIGNED

Optical atomic clocks can measure time with an uncertainty on the order of just a few seconds over the age of the universe. Measurement with this level of precision has far-reaching applications, from the measurement of minute changes in the fundamental physics constants revealing physics beyond the Standard Model, to technological advances in navigation and network synchronization. To unlock the full potential of atomic clocks, we must minimize the dependence on the precision of an external optical resonator and miniaturize the experimental apparatus required, allowing for field-deployability. In this project, I will realize the first ever continuous superradiant laser based on 88-Sr atoms, theoretically proposed to reach a linewidth even smaller than the ultra-narrow natural linewidth of the clock transition in strontium. I will then use the continuous superradiant laser as the basis for the first ever continuous superradiant optical clock, minimizing uncertainties due to the Dick effect. Further, during the fellowship I will use my previous experience with compact cold atom systems to miniaturize the experimental apparatus as a step towards a compact continuous superradiant clock.

Projet PrecisionTopMass (Horizon Europe, appel à projets 2023)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Physics
Statut du projet : CLOSED

This project will have a major impact on the LHC extraction of the top quark mass, which is one of the most important measurements to be performed in the coming years. Currently, the top mass measurement suffers from theoretical imprecision, including an over-reliance on Monte Carlo (MC) simulations and an inadequate treatment of non-perturbative hadronization physics, with no systematic prospects for improvement. To address these challenges, this project adopts cutting-edge approaches using the powerful theoretical tools of effective field theories of QCD and novel jet substructure techniques. The proposed action will pave the way for a sub-GeV precise measurement in a well-defined field-theoretic mass scheme, eliminating long-standing uncertainties in the current methodology. It will also simultaneously tackle the challenges of systematically accounting for hadronization effects, which have also impacted jet substructure determinations of the strong coupling constant. The project leverages the Experienced Researcher’s (ER) unique expertise in this area and established collaborations with LHC experimentalists. Its cornerstone is the use of energy-energy correlators (EECs), which enable precision measurements in the complex environment of the LHC by efficiently removing various sources of contamination in the jets while providing a theoretical control superior to conventional jet substructure observables. Capitalizing on the ER’s recent proposal to exploit EECs on boosted top quarks as a top mass-sensitive probe, we will compute state-of-the-art theoretical predictions for this top mass-sensitive observable with next-to-next-to-leading logarithmic (NNLL) accuracy, well beyond the reach of current MC simulations. With the primary goal of enabling a direct comparison of theoretical prediction, we will develop a systematic, model-independent field-theoretic framework for describing hadronization corrections in complex modern jet substructure observables.

Projet YcascadE (Horizon Europe, appel à projets 2023)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Chemistry
Statut du projet : SIGNED

The development of green and robust technologies for the conversion of renewable feedstock into high-value chemicals is of great interest and challenging for the chemical industry. Although L-α-amino acids can be sustainably produced from renewable feedstock by fermentation, these amino acids are rarely being used as starting material for the chemical synthesis of high-value chiral molecules due to the lack of efficient and highly selective biocatalytic methodologies . In this project, I will design and develop a modular approach for biocatalysis in vivo enabling the conversion of natural amino acids into enantiopure alpha-chiral amines and amino-alcohols, which are important intermediates or final products for the pharmaceutical, agrochemical and fine chemical industries. Saccharomyces cerevisiae will be selected as the host organism for the biocatalytic pathway because its genome is well-known, is suitable for large scale operation, and will allow to obtain higher productivity than using bacterial strains. A library of integrative plasmids expressing the enzymes will be constructed and transformed to S. cerevisiae to obtain a yeast cell factory. The system will be optimized both on the genetic level and on the bioprocess level. The working plan will include an interdisciplinary approach involving molecular biology techniques together with metabolic engineering as well as optimization of conditions for biotransformation. Additionally, analytical chemistry methodologies for determination of yield, purity and enantiomeric excess of the products and intermediates will be required. While the state-of-the-art proves the feasibility of the project, by using our proposed approach with resting S. cerevisiae cells, we expect to make a major break-through in the field in terms of increase productivity (e.g., space-yield; space-time-yield; total yields from substrate) and, moreover, a wider applicability of the resulting platform due to the modularity approach.

Projet Co-ARMs (Horizon Europe, appel à projets 2021)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Chemistry
Statut du projet : CLOSED

Artificial metalloenzymes (ARMs), that is, designed enzymes containing a synthetic metal co-factor within a protein framework, locates itself as a promising area of research for the discovery and development of new transformations. We set our attention in cobalt complexes as co-factors, a first-row, earth-abundant, and non-toxic metal that is currently underexplored in ARMs. Cobalt complexes present a highly versatile chemistry, including they ability to participate in allylic functionalization reactions, an important transformation for the pharmaceutical industry as can deliver structural frameworks that are widely spread in biological active compounds. Allylic functionalization reactions are underdeveloped in bio-catalysis, and the expansion of important homogeneous reactions, as the before mentioned, into the realm of enzymes is an absolute necessity for the development of sustainable chemistry. Co-ARMs (Cobalt-containing ARtificial Metalloenzymes) proposal aims to create new generations of ARMs relying on the unique reactivity of synthetic cobalt complexes in allylic substitution reactions, an unknown reaction in enzyme catalysis and an underexplored metal for the discovery of new-to-nature reactions. The proposal balance between host expertise (Dr. Gerard Roelfes) in bio-inorganic and chemical biology, and the researchers’ skills (Dr. Franco Della-Felice) in synthetic organic chemistry. The result is a cooperative field where two different branches converge with the aim to develop new concepts and environmentally compatible tools in chemistry to access organic frameworks of high significance to the pharmaceutical and agrochemical industries.

Projet SMART (Horizon Europe, appel à projets 2021)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Physics
Statut du projet : TERMINATED

Rapid progress in the regime of Artificial Intelligence and Internet-of-Things has enthused the development of fast and energy-efficient hardware to support future computing needs. One of the most prominent solutions is the deployment of cross-disciplinary resources for mimicking the performance of a Human Brain, also known as neuromorphic computing. It relies on electronic components that could replicate the functioning of neurons and synapses. Designing such novel electronics needs the development of cost-effective, fast and reliable materials with tunable functionality. A fundamental understanding of these materials will pave the foundation of innovative device designs and strategies for their large-scale integration for neuromorphic architectures. In this context, the proposed project intends to deliver artificial neurons by developing thin-films of a novel material (TbMnO3) that is capable of demonstrating a Negative Differential Resistance (NDR). The idea is to utilise the fundamental understanding of multi-dimensional (electrical, optical, mechanical and magnetic) control of NDR which is not explored yet and is possible in TbMnO3. NDR enables a two-terminal device to display self-oscillations due to applied electrical spikes. The spiking electrical currents could be used to govern the behaviour of these oscillations and emulating the leaky, integrate, and fire behaviour of biological neurons. Once such a performance is achieved, the device will further be integrated into oscillatory neural networks array for demonstration of complex computing tasks such as image recognition and imitating human behaviour. The project will unite the applicant’s expertise in synaptic devices and materials engineering with the extensive experience of the host-labs in thin-film and neuromorphic devices. Importantly, the project will warranty catapulting the applicant’s international recognition as an independent researcher and will improve his career prospects.

Projet SchoolandTransitions (Horizon Europe, appel à projets 2021)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Social Sciences and Humanities
Statut du projet : SIGNED

Becoming a parent and moving in to live with a partner are major life events determining individual’s life chances and outcomes. Transitioning to parenthood and partnership at very young age (also called off-time transitions), have been linked to adverse outcomes along the life course. A potentially key influence on off-time transition to parenthood and partnership are secondary schools and classmates, as adolescents spend a large part of their time in school, surrounded by their peers. Project SchoolandTransitions will be the first to investigate the role of secondary schools and classmates in off-time transitions to parenthood and partnership. This project aims to gain a complex understanding of the influence of schools and classmates and its interaction with individuals’ characteristics and family backgrounds. To achieve this, I set three objectives: (1) decompose the effect of the school as a social context and the effect of peer influence of classmates; (2) examine if and how can classmates and school contexts mitigate or exacerbate the influence of family background; and (3) assess how the effect of classmates and school contexts changes over the years since leaving the secondary school.
