Phase-Noise-Induced Heating in Optical Lattices
Jean Paul Nohra, Cyprien Daix, Joris Verstraten +5
We experimentally and theoretically study the origin of heating in optical lattices by disentangling the respective roles of intensity and phase noise depending on the lattice para…
Floquet engineering of tight-binding Hamiltonians in momentum space lattices
D. Ronco, F. Arrouas, N. Ombredane +4
Quantum simulation with ultracold atoms provides a versatile platform to emulate condensed-matter models. In particular, momentum-space lattices enable the realization of programma…
Many-body dynamical localization in Fock space
Nathan Dupont, Bruno Peaudecerf, David Guéry-Odelin +4
We investigate the emergence of many-body dynamical localization (MBDL) in the Fock space of an interacting two-mode bosonic system subject to periodic driving. Using a mapping to…
Time-optimal force sensing with ultracold atoms
Nicolas Ombredane, Eloi Flament, Charles Babin +3
We develop a time-optimal approach to force sensing using a Bose-Einstein condensate in a shaken optical lattice. Optimal control protocols are derived from a Fisher information fr…
Probing non-ergodicity and symmetry via coherent forward scattering in a shaken rotor
F. Arrouas, J. Hébraud, N. Ombredane +9
The Coherent Backscattering (CBS) peak is a well-known interferential signature of weak localization in disordered or chaotic systems. More recently, a second interference feature…
Probing the Fermi Sea Topology in a Quantum Gas
Cyprien Daix, Pok Man Tam, Maxime Dixmerias +5
Pauli's exclusion principle forces fermions to occupy distinct quantum states, creating a filled region of momentum space at low temperature, the Fermi sea, whose topology governs…
