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…
A Maxwell Fish-Eye Lens in a Bose-Einstein Condensate
Jelte Duchêne, Elinor Kath, Floriane Arrouas +7
We experimentally realize an analogue of the optical Maxwell fish-eye lens (MFEL) using phononic excitations in a Bose-Einstein condensate (BEC). A MFEL is characterized by a radia…
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…
Floquet operator engineering for quantum state stroboscopic stabilization
Floriane Arrouas, Lucas Gabardos, Nicolas Ombredane +6
Optimal control is a valuable tool for quantum simulation, allowing for the optimized preparation, manipulation, and measurement of quantum states. Through the optimization of a ti…
A regular Hamiltonian halting ratchet for matter wave transport
N. Dupont, L. Gabardos, F. Arrouas +4
We report on the design of a Hamiltonian ratchet exploiting periodically at rest integrable trajectories in the phase space of a modulated periodic potential, leading to the linear…
Emergence of a tunable crystalline order in a Floquet-Bloch system from a parametric instability
Nathan Dupont, Lucas Gabardos, Floriane Arrouas +6
Parametric instabilities in interacting systems can lead to the appearance of new structures or patterns. In quantum gases, two-body interactions are responsible for a variety of i…
Phase-space distributions of Bose-Einstein condensates in an optical lattice: Optimal shaping and reconstruction
N. Dupont, F. Arrouas, L. Gabardos +5
We apply quantum optimal control to shape the phase-space distribution of Bose-Einstein condensates in a one-dimensional optical lattice. By a time-dependent modulation of the latt…
