My research interests are centered within condensed matter theory & statistical mechanics, in particular in the area of strongly correlated systems. A few research themes :
Quantum physics
Condensed Matter Theory, Quantum magnetism, Superconductors, Cold atoms
Many-body localization, out of equilibrium quantum physics
Neural networks & quantum physics
Statistical mechanics & constrained models
High-performance computational physics, numerical techniques
Relation to quantum information theory
Participation to open-source projects and softwares : ALPS project (quantum Monte Carlo code SSE), Shift-invert Many Body Localization, NetKet
NEW POSITION RE-OPENED
2024-25 : Postdoc position on Many-Body Localization and related quantum out-of-equilibrium phenomena. Contact me
NEW
2025 : PhD topics available on Neural quantum states in quantum many-body physics and Many-Body Localization. To be precise, I have unfortunately no funding for a PhD position, but if a student obtains independent funding (CDSN, CDSX, International funding etc), there are many problems to explore in these areas ! These topics involve (some) development of new numerical methods, so students with a computational heart are strongly encouraged to contact me if they are interested to know more. Funded M2 internships are also possible, but I would prefer to reserve internships in case a PhD is possible afterwards.
