Biography
I am an assistant professor in the Theory group of the Laboratory of Solid State Physics of the University Paris-Saclay. My main research interests are ab-initio theories of condensed matter, topological states of matter, and strongly correlated electron systems.
Applications for internships in 1st or 2nd year of Master are always welcome. Please feel free to contact me if you have any question. You can find some of my internship proposals on the website of the ICFP. There is currently no postdoc opening in my group.

Topological states in interacting systems
We study topological states of matter in contexts where it is necessary to go beyond standard band theory, in particular when correlations are important. In a recent paper, we studied the Hall conductivity in topological systems with Hatsugai-Kohmoto interactions, and found a non-quantised Hall conductivity in the presence of a Zeeman field. In another work, we defined the zeros surface, a set of points in reciprocal space formed by the zeros of diagonal elements of the Green’s function, and showed that it allows one to directly visualise the Z2 topological invariants in inversion-symmetric systems.

Ab-initio theories of condensed matter
We collaborate with experimental teams on various systems, such as two-dimensional Van der Waals heterostructures and compounds exhibiting charge density wave phases. Using density functional theory (DFT) and many-body perturbation theory, in the framework of the GW approximation, we calculate observables which enhance our understanding of the measured physics.

Gravitational analogues
We designed low-dimensional electronic models, related to Weyl semimetals, which mimic some of the properties of gravitational systems. In particular, we studied the dynamics of wave packets of electrons in 1D and 2D lattice models, the spectral properties of these models, and ground-state thermalisation near a gravitational horizon.

Finite-size topological insulators
We investigate the influence of finite thickness on properties of topological insulators.
We studied a minimal model for topological insulators in a slab geometry. One parameter of our model, namely the Dirac velocity perpendicular to the slab, distinguishes between two qualitatively distinct situations: when it is zero, we find that the topological invariants of the 3D system can be entirely deduced from properties of the slab. However when it is not zero, a new phase arises, with surface states but without band inversion. We also investigated this model for large dispersions perpendicularly to the slab and unveiled a regime where the slab displays non-trivial topological invariants but nonetheless extrapolates towards a trivial 3D state.
The new phase which displays surface states without band inversion is localised close to topological phase transitions. We therefore studied ZrTe5, which was shown to be a strong topological insulator, on the border of a weak topological insulating phase. We derived a model for this material fitted to ab-initio calculations and showed that it matches many experimental signatures, including optical, transport, and spectroscopic results.
