We are a theoretical research group working at the intersection of
atomic and molecular physics, condensed matter physics, quantum information science, and quantum optics. We are based at the Institut de Science et d’Ingénierie Supramoléculaires (ISIS) of the University of Strasbourg.
Quantum Optics, Cavities and Molecules
The study of strong light-matter interactions is playing an increasingly crucial role in understanding as well as engineering new states of matter with relevance to the fields of quantum optics, quantum information, solid state physics, quantum chemistry and material science.
We are particularly interested in investigating how light-matter interactions can enhance transport properties of excitons and charge in molecular semi-conductors for basic science and quantum technologies.
From Few-particle Interactions to Quantum Gases, Fluids and Solids
We are interested in the design of inter-particle atomic and molecular interactions at cold and ultracold temperatures using quantum optical techniques and the investigation of many-body quantum phenomena resulting from these interactions in cold gases. Recent interests include:
- long-range interactions with Rydberg atoms, dipolar atoms, polar molecules, cold ions
- supersolids, superglasses
- topological models of fermions
- disordered quantum phases
Numerical methods in Many-Body Quantum Physics
We utilize and develop advanced theoretical techniques for the numerical solution of the many-body problem in closed and open quantum systems. These include:
- Path-Integral Quantum Monte-Carlo
- Density-Matrix Renormalization Group methods (DMRG)
- time-dependent matrix product state methods (t-DMRG/TEBD)
- Semiclassical discrete truncated Wigner approximation
- New pre-print on operator entanglement dynamics January 14, 2022
- ECOS-Sud Project: Collaboration with Chile ahead December 21, 2020
- Mobility edge of the two-dimensional Bose-Hubbard model December 9, 2020
