Vortex NOON states for rotation sensing

Simon Dengis, Nathan Dupont, Peter Schlagheck +1

We introduce a scheme to generate NOON states of few-body bosonic vortices and demonstrate their application as high-precision rotation sensors. Our approach is based on cold atoms…

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…

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…

Extreme fragmentation of a Bose gas

Nathan Dupont, Amit Vashisht, Nathan Goldman

Fragmentation of an interacting Bose gas refers to the macroscopic occupation of a finite set of single-particle eigenstates. This phenomenon is related to the notion of particle-n…

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…

Quantum state control of a Bose-Einstein condensate in an optical lattice

N. Dupont, G. Chatelain, L. Gabardos +5

We report on the efficient design of quantum optimal control protocols to manipulate the motional states of an atomic Bose-Einstein condensate (BEC) in a one-dimensional optical la…

Observation and control of quantized scattering halos

G. Chatelain, N. Dupont, M. Arnal +5

We investigate the production of s-wave scattering halos from collisions between the momentum components of a Bose-Einstein condensate released from an optical lattice. The lattice…

Chaos-assisted tunneling resonances in a synthetic Floquet superlattice

M. Arnal, G. Chatelain, M. Martinez +7

The field of quantum simulation, which aims at using a tunable quantum system to simulate another, has been developing fast in the past years as an alternative to the all-purpose q…
