    The Young International Academics postdoctoral programme (YIA) is a career development program proposed by the University of Luxembourg (Uni.lu) to nurture early-career postdoctoral applicants to gain momentum in interdisciplinary/intersectoral research. YIA applicants are international talents willing to propose and realize their own interdisciplinary research projects through a bottoms-up approach. YIA will welcome, in two calls, a total of 10 postdoctoral fellows with 36-month contracts over 5 years. YIA is open to all disciplines and sectors, involving Uni.lu in the drive towards an increased interdisciplinarity and intersectorality, which are strategic for Uni.lu, for the country and for Europe. A unique aspect of YIA is its integration into Uni.lu’s Institute for Advanced Studies-Luxembourg (IAS) created in 2019 to promote interdisciplinarity and outreach towards the society. This integration provides the YIA fellows with (1) a supervision for interdisciplinary and intersectoral research with more than 350 potential (co)-supervisors, and with about 350 potential public-private partners, (2) peer and cross-generational interactions/mentoring through the IAS fellows, invited distinguished senior scientists, early career researchers, and a mandatory academic or industrial secondment, and (3) a truly international flavour in an environment that cherishes diversity and excellence. YIA fellows recruited at Uni.lu are offered competitive contracts with mobility fellowships and access to excellent research infrastructures. A professor of Uni.lu provides supervision for the primary discipline of the applicant’s project and a co-supervisor covers the complementary discipline/sector. The YIA fellows are offered an “à la carte” training including mandatory courses, to suits the fellow’s career aspirations, increase the fellow’s interdisciplinarity and employability. The YIA programme will support a rapid ramp into a long-term Uni.lu funding of postdoctoral IAS fellows.

    The quantum-mechanical theory of molecular interactions is firmly established, however its applicability to large molecular complexes is hindered by the rather high computational cost of quantum calculations required to achieve high accuracy. We propose a paradigm shift in the modeling and conceptual understanding of electrostatic and electrodynamic molecular interactions in many-particle systems from the perspective of (quantum) field theory. This development is critical to accurately and efficiently model increasingly intricate and functional molecular ensembles with millions of atoms subject to external excitations (static, thermal, and optical fields; variation in the number of particles; and/or arbitrary macroscopic boundary conditions). This molecular size covers a wide range of functional biological systems, including solvated protein/protein and enzyme/DNA complexes. The theoretical developments in this project will concentrate on two main fronts: (WP1) fundamental quantum electrodynamics (QED) theory of molecular interactions based on many-body oscillator Hamiltonians, (WP2) second-quantized field theory (FIT) approach to molecular Hamiltonians for modeling large-scale systems with 10^4-10^6 atoms. The applicability of these challenging developments to realistic molecules will be ensured by: (WP3) implementation of non-local machine learning force fields based on second-quantized matrix Hamiltonians for efficient molecular dynamics simulations of molecular ensembles, (WP4) implementation of QED/FIT methods in an open-source package FITMOL for increasing the accuracy, improving the efficiency, and enhancing the insight that one obtains from quantum-mechanical calculations of large molecules. It is my vision that revealing fundamental mechanisms of functional (bio)molecules with millions of atoms requires a radically new field-theory approach to molecular interactions. Achieving this goal will be the main breakthrough of the FITMOL project.

    Product counterfeiting, sometimes related to the theft of the original, has emerged as a significant economic issue, with the market value of pirated products equalling or exceeding the gross domestic product of some European countries. A 2016 report from OECD in cooperation with the EU Intellectual Property Office (EUIPO) found that in 2013 counterfeit products sold were worth €375 billion, totalling 2.5% of global trade. Counterfeit products range from high-end consumer luxury goods, to business-to-business products such as machines, chemicals, raw materials or spare parts, and to common consumer products such as toys, pharmaceuticals, cosmetics and food. Some counterfeit products, in particular in the latter category but also, e.g., spare parts, are of low quality, thus creating additional health and safety threats. Valuable raw materials can be stolen at the site of production or in transit, sometimes being replaced by a copy that can be difficult to detect as such by the receiver, sometimes reappearing on the market with no means to detect them as stolen. VALIDATE aims to investigate the commercial feasibility of Cholesteric Spherical Reflectors (CSRs) coatings as high-security identification tags, within a work plan that aims to take our innovation from a Technology Readiness Level (TRL) of 4 to 6/7. This will serve as a key stepping stone towards full commercial exploitation of our CSRs as a game-changing material for authentication. The value proposition of VALIDATE is a physical identifier tag that is effectively unclonable as a result of the manufacturing process, naturally tamper-evident and hard to simulate due to the complexity of the generated patterns. VALIDATE’s end goal is to have a comprehensive description of the commercial feasibility of our technology and, if positive, what commercialization route has the best risk/benefit ratio.

    The development of non-equilibrium statistical physics has provided a powerful tool to understand and describe the collective dynamics of a wide range of chemical, biological and social systems. In this framework, active matter has raised as one of the most significant topics in this domain, mainly addressing the features of many-body dynamics with self-propelled units such as bacteria colonies, bird flocks and pedestrians walks. Based on the observation of collective motion like size synchronization and wave propagation in epithelial tissues, we will introduce a new class of active matter models to understand the microscopic physical mechanisms underlying these dynamics. Motivated by the physical complexity of biological units, we will extend the concept of activity to the ability of the individual particle to change an internal degree of freedom, related to its size or to an energetic landscape, and we will explore the non-equilibrium phase transitions and collective behavior originating from this property. Our research project consists of three main objectives: (i) we will first extensively investigate the phase diagram of actively deforming particles, and compare it to the experimental observations to capture the essential mechanisms of phase transitions and wave propagation; (ii) we will then explore the interplay between phase synchronization and microscopic energy landscapes to understand the minimal ingredients for liquid-liquid phase separation, where two fluids spontaneously separate from a mixed phase; (iii) we will finally study the energetics of these models, quantifying the energy gain/cost of each phase and studying how phase transitions can be optimized. The exploration of these models represents a potential breakthrough in the physics of soft matter, clarifying the microscopic ingredients at the basis of several chemical and biological dynamics and introducing a fertile ground for the emergence of new physics.
