Squeezing light with optomechanical and spin-light quantum interfaces
Gian-Luca Schmid, Manel Bosch Aguilera, Chun Tat Ngai +6
We investigate squeezing of light through quantum-noise-limited interactions with two different material systems: an ultracold atomic spin ensemble and a micromechanical membrane.…
Many-Body Dephasing by Hole Motion in a Spin-Orbit-Coupled Mott Insulator
A. Ghermaoui, M. Bosch Aguilera, R. Bouganne +4
We use Ramsey interferometry to study spin dynamics in the strongly interacting regime of spin-orbit-coupled quantum gases in one-dimensional optical lattices. We observe an intrin…
Dynamics of spatial phase coherence in a dissipative Bose-Hubbard atomic system
Rémy Vatré, Raphaël Bouganne, Manel Bosch Aguilera +4
We investigate the loss of spatial coherence of one-dimensional bosonic gases in optical lattices illuminated by a near-resonant excitation laser. Because the atoms recoil in a ran…
Optical coherent feedback control of a mechanical oscillator
Maryse Ernzer, Manel Bosch Aguilera, Matteo Brunelli +5
Feedback is a powerful and ubiquitous technique both in classical and quantum system control. Its standard implementation relies on measuring the state of a system, processing the…
Adiabatic Quantum Zeno Dynamics of Bosonic Atom Pairs with Large Inelastic Losses
Manel Bosch Aguilera, Alexis Ghermaoui, Rémy Vatré +3
We report on experiments exploring the non-Hermitian dynamics of pairs of two-level atoms tightly confined in an optical lattice and driven by a near-resonant laser. Although spont…
Coherent feedback cooling of a nanomechanical membrane with atomic spins
Gian-Luca Schmid, Chun Tat Ngai, Maryse Ernzer +3
Coherent feedback stabilises a system towards a target state without the need of a measurement, thus avoiding the quantum backaction inherent to measurements. Here, we employ optic…
Strong correlations in lossy one-dimensional quantum gases: from the quantum Zeno effect to the generalized Gibbs ensemble
Davide Rossini, Alexis Ghermaoui, Manel Bosch Aguilera +5
We consider strong two-body losses in bosonic gases trapped in one-dimensional optical lattices. We exploit the separation of time scales typical of a system in the many-body quant…
Non-linear Relaxation of Interacting Bosons Coherently Driven on a Narrow Optical Transition
M. Bosch Aguilera, R. Bouganne, A. Dareau +4
We study the dynamics of a two-component Bose-Einstein condensate (BEC) of Yb atoms coherently driven on a narrow optical transition. The excitation transfers the BEC to a…
Clock spectroscopy of interacting bosons in deep optical lattices
R. Bouganne, M. Bosch Aguilera, A. Dareau +3
We report on high-resolution optical spectroscopy of interacting bosonic Yb atoms in deep optical lattices with negligible tunneling. We prepare Mott insulator phases with…
Revealing the topology of quasicrystals with a diffraction experiment
A. Dareau, E. Levy, M. Bosch Aguilera +4
Topological properties of crystals and quasicrystals is a subject of recent and growing interest. This Letter reports an experiment where, for certain quasicrystals, these properti…
