Abstract: The ECRIN project aims to better understand the effects of human-induced climate and environmental changes on health and biodiversity, in order to propose adaptation and mitigation measures. It builds on the achievements of the CLIMIBIO and IRenE projects (CPER 2015–2020) to form a national and European consortium of laboratories engaged in multidisciplinary environmental research that combines advanced research with practical applications in the economic sector.

ECRIN covers a broad disciplinary spectrum, from physical chemistry to urban planning, in order to:

1. Characterize the physical and chemical properties of urban, suburban, and rural environments using experimental and theoretical approaches;
2. Assess their impacts on human health and ecosystem services;
3. Propose appropriate mitigation and adaptation measures (behavioral changes, transportation, land-use planning);
4. Promote the transfer of innovations to the private sector.

Abstract: My research project focuses on the quantum-to-classical transition, a fundamental problem aimed at understanding how the quantum properties of a system disappear to give way to classical behavior. This transition is governed by decoherence, a phenomenon resulting from the entanglement between a system and its environment, and represents a major obstacle for quantum technologies. Despite recent advances, notably with the quantum Darwinism proposed by Zurek, the physical understanding of the role of observers and the reconstruction of a shared classical picture remains incomplete.

The project proposes to address this question from an interdisciplinary perspective, at the intersection of quantum physics, mathematics, and quantum computing. The goal is to develop a general framework for the physics of observers, based on resource theory, in order to analyze how a classical description can emerge from a quantum system and be shared among multiple observers.

A key part of the project is devoted to studying entanglement between indistinguishable particles. In particular, the project aims to examine entanglement between electrons within the framework of quantum electronic optics, a rapidly developing field that allows for the manipulation of individual electrons in a manner analogous to photons in quantum optics.

Abstract: DOMMiNO aims to develop innovative Mamyshev fiber laser oscillators that would overcome the technological barriers associated with this type of femtosecond source. We will seek to understand the underlying principles of this type of oscillator and identify the physical phenomena that govern it. The project is based on numerical studies using tools developed in-house. This understanding will guide the experimental work to achieve the objectives regarding energy, duration, and temporal compression quality. We will also investigate certain internal dynamics of these oscillators that remain poorly understood to date. We will then demonstrate the use of these sources for multimodal nonlinear micro-endoscopy (2PEF and SHG). To our knowledge, the use of a single oscillator has not yet been demonstrated for multiphoton microscopy applications, and even less so in the context of micro-endoscopy. Finally, we will work to extend the emission spectral range beyond 1200 nm to make the source compatible with micro-endoscopy using non-degenerate two-photon fluorescence excitation and multi-wavelength 2PEF. We will attempt to demonstrate a proof of concept for these types of endoscopic imaging, which, to our knowledge, is a first, regardless of the source and wavelengths used.

Abstract: 

This project aims to study the formation kinetics and stability of mixed hydrates (CO2-N2, CO2-CH4) in saline environments, with a focus on their potential for effective CO2 sequestration. Raman spectroscopy is used to monitor hydrate formation and CO2 trapping as a function of temperature, pressure, and CO2 solubility. The role of dissolved salts (e.g., NaCl, CaCl2) is examined to understand their impact on hydrate stability and molecular selectivity. The effects of porous materials, mimicking marine sediments, are also studied to assess how composition and porosity influence the efficiency of CO₂ trapping within hydrates.

The new data and analyses obtained in this way could contribute to the development of CO2 storage technologies in saline environments that are both more efficient and more reliable, thereby supporting climate change mitigation efforts. They will also benefit geophysical models of icy moons by providing new constraints on the composition of hydrates formed in subsurface oceans.

Abstract: This project is part of an initiative to promote scientific literacy and foster an appreciation for physics among young audiences. It aims to spark curiosity and interest in science among middle and high school students. The goal is to introduce them to the fascinating world of physics, stimulating their curiosity, critical thinking, and passion for scientific discovery.

A dedicated space will host interactive and educational experiments illustrating fundamental concepts of physics through devices that are both entertaining and spectacular, such as trichromatic holography and single-photon light interference. These experiments will provide an ideal setting for engaging with scientific staff, inspiring future careers, and strengthening the ties between education, research, and society.
