Intérêts de recherche/Research Interests:
Understanding random fractal patterns is at the core of the comprehension of many physical phenomena or mathematical structures, and the Brownian motion is a historical example of such structures. I participated to the understanding of newly constructed planar random curves or interfaces (called SLE), a theme which fits into random geometry. In collaboration with M. Bauer, we developed bridges linking probabilistic approaches from mathematicians with those of physicists based on field theories. |
Conformal field theories (CFT) and integrable systems find applications to 2d phase transitions, to critical quantum systems, and they are closely related to string theories. I have been involved in the development of the CFT methodological tools. Part of my work relies on deciphering and using quantum symmetries, others have a more mathematical flavour related either to algebraic structures of CFT and to geometrical aspects of Riemann surfaces. |
Turbulent phenomena are ubiquitous in many every day phenomena, but still lack a complete theoretical understanding. I participated to the physical and mathematical collective understanding of intermittence phenomena in the (up-to-now) unique solvable model of turbulent transport, and to enlighten traces of conformal invariance in two dimensional turbulence. |
Experimental progresses in controlling quantum systems gave new impetus to study unexplored territory of quantum dynamics, and simultaneously to answer old questions of quantum mechanics. My recent research aims at studying quantum stochastic processes, their mathematical structures and their applications to the physics of monitored or open quantum systems, in or out of equilibrium. In particular, I analysed an iconic model of stochastic quantum many-body dynamics, the quantum symmetric simple exclusion process. |
