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…
Symmetry-Induced Logarithmic Relaxation in the Quantum Kicked Rotor
Julien Hébraud, Floriane Arrouas, Bruno Peaudecerf +6
We study the effect of discrete symmetries on coherent multiple scattering in the quantum kicked rotor. When the initial momentum is set to zero -- as in recent Bose-Einstein conde…
Localization Landscape in Non-Hermitian and Floquet quantum systems
David Guéry-Odelin, François Impens
We propose a generalization of the Filoche--Mayboroda localization landscape that extends the theory well beyond the static, elliptic and Hermitian settings while preserving its ge…
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…
Optimal control over the full counting statistics in a non-adiabatic pump
François Impens, Felippo M. D'Angelis, David Guéry-Odelin +2
We introduce a systematic procedure based on optimal control theory to address the full counting statistics of particle transport in a stochastic system. Our approach enhances the…
Unitary Transformations using Robust Optimal Control on a Cold Atom Qudit
E. Flament, N. Ombredane, F. Arrouas +4
In this paper, we design and experimentally implement various robust quantum unitary transformations (gates) acting on -dimensional vectors (qudits) by tuning a single control p…
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…
Optimal control of a Bose-Eintein Condensate in an optical lattice: The non-linear and two-dimensional cases
E. Dionis, B. Peaudecerf, S. Guérin +2
We numerically study the optimal control of an atomic Bose-Einstein condensate in an optical lattice. We present two generalizations of the gradient-based algorithm, GRAPE, in the…
Interaction of a propagating guided matter wave with a localized potential
Giovanni Luca Gattobigio, Antoine Couvert, Bertrand Georgeot +1
We provide a theoretical framework to describe the interaction of a propagating guided matter wave with a localized potential in terms of quantum scattering in a confined environme…
