Full counting statistics of interacting lattice gases after an expansion: The role of the condensate depletion in the many-body coherence
Gaétan Hercé, Jan-Philipp Bureik, Antoine Ténart +3
We study the full counting statistics (FCS) of quantum gases in samples of thousands of interacting bosons, detected atom-by-atom after a long free-fall expansion. In this far-fiel…
Observation of pairs of atoms at opposite momenta in an equilibrium interacting Bose gas
Antoine Tenart, Gaétan Hercé, Jan-Philipp Bureik +2
Quantum fluctuations play a central role in the properties of quantum matter. In non-interacting ensembles, they manifest as fluctuations of non-commuting observables, quantified b…
Studying the low-entropy Mott transition of bosons in a three-dimensional optical lattice by measuring the full momentum-space density
Gaétan Hercé, Cécile Carcy, Antoine Tenart +4
We report on a combined experimental and theoretical study of the low-entropy Mott transition for interacting bosons trapped in a three-dimensional (3D) cubic lattice -- namely, th…
Thermal counting statistics in an atomic two-mode squeezed vacuum state
M. Perrier, Z. Amodjee, P. Dussarrat +5
We measure the population distribution in one of the atomic twin beams generated by four-wave mixing in an optical lattice. Although the produced two-mode squeezed vacuum state is…
Observation of ultra-strong spin-motion coupling for cold atoms in optical microtraps
A. Dareau, Y. Meng, P. Schneeweiss +1
We realize a mechanical analogue of the Dicke model, achieved by coupling the spin of individual neutral atoms to their quantized motion in an optical trapping potential. The atomi…
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…
Near-ground-state cooling of atoms optically trapped 300nm away from a hot surface
Y. Meng, A. Dareau, P. Schneeweiss +1
Laser-cooled atoms coupled to nanophotonic structures constitute a powerful research platform for the exploration of new regimes of light-matter interaction. While the initializati…
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…
Cold-atom based implementation of the quantum Rabi model
P. Schneeweiss, A. Dareau, C. Sayrin
The interaction of a two-level system (TLS) with a single bosonic mode is one of the most fundamental processes in quantum optics. Microscopically, it is described by the quantum R…
Fictitious magnetic field gradients in optical microtraps as an experimental tool for interrogating and manipulating cold atoms
Bernhard Albrecht, Yijian Meng, Christoph Clausen +3
Optical microtraps provide a strong spatial confinement for laser-cooled atoms. They can, e.g., be realized with strongly focused trapping light beams or the optical near fields of…
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…
Doppler Spectroscopy of an Ytterbium Bose-Einstein Condensate on the Clock Transition
A. Dareau, M. Scholl, Q. Beaufils +3
We describe Doppler spectroscopy of Bose-Einstein condensates of ytterbium atoms using a narrow optical transition. We address the optical clock transition around 578 nm between th…
