Some few words about my research

My research work focus on mathematical physics: more precisely to problems arising from quantum mechanics.  I am particularly interested in fermionic particles.

Keywords: spectral theory, PDEs, semiclassical analysis, spectral clusters and L^p estimates, bosonization techniques.

2. Weyl laws for interacting particles - 2023. (Preprint)

Publications or accepted papers

1. Fermionic semiclassical Lp estimates, to appear in Journal of Functional Analysis - 2022. (Preprint) 


PhD manuscript

I have studied in my PhD thesis the concentration of fermions  in the semiclassical limit. In the case without interactions, it remains to study the orthogonal families of eigenfunctions of Schrödinger operators. I am intesrested in Weyl laws in models with interactions.

I like fruits. A blog dedicated to this subject is under construction.

You can find here a non exhautive list here that I wrote for friends who travelled in Vietnam.
