Séminaire du LPTMS: Igor Ferrier-Barbut
Light scattering by cold atomic arrays, towards quantum simulation of dissipative many-body physics
Igor Ferrier-Barbut (LCF, Institut d’Optique)
Single atom trapping using tightly focused optical tweezers has emerged as a new versatile experimental platform. Optical holographic techniques allow to engineer 1, 2 or 3D ensembles of atoms in vacuum, that have an almost arbitrary geometry and are nearly free of defects. Typically, these techniques are combined with an excitation of the atoms to Rydberg states, that allow to engineer an interaction between the individual atoms, realizing quantum simulators for quantum many-body physics. In this presentation I will focus on our progress to study dissipative quantum many-body systems in such platforms. For this we use light-induced resonant dipole-dipole interactions between two-level atoms, which contain both a conservative and dissipative part. We will present first experiments where we were able to increase the effect of such interactions, and prospects to reach the strongly interacting regime.
