Phases of a rotating Bose-Einstein condensate trapped in a hard-wall potential
Hélène Perrin, G. M. Kavoulakis
We investigate the rotational properties of a zero-temperature Bose-Einstein condensed gas, which is confined in a hard-wall potential. For weak interactions the gas carries its an…
From harmonic to sound-like oscillations in a quantum gas confined in a gravity compensated shell trap
Matthieu Cassus, Rishabh Sharma, Maxime Pesche +4
We study the center of mass oscillations of a quantum gas in a shell shaped trap in the presence of a vertical force opposed to gravity. The measured harmonic frequency at the bott…
Course on two-dimensional quantum gases
Hélène Perrin
This course on two-dimensional quantum gases, prepared for the S{ã}o Paulo ICTP-SAIFR IVth School on Light and Cold Atoms, is organized into three lectures. The first introductory…
Universal Behavior on the Relaxation Dynamics of Far-From-Equilibrium Quantum Fluids
Sarah Sab, Michelle A. Moreno-Armijos, Arnol D. García-Orozco +6
Investigating the initial conditions that lead many-body quantum systems to an out-of-equilibrium state is fundamental for understanding their thermalization dynamics. In this work…
Classical field simulation of vortex lattice melting in a two-dimensional fast rotating Bose gas
Sálvio Jacob Bereta, Lucas Madeira, Mônica A. Caracanhas +2
We present a classical field simulation study of the thermal melting of a two-dimensional vortex lattice in a rotating Bose gas, focusing on the role of finite-size effects on the…
Soliton turbulence of a strongly driven one-dimensional Bose gas
Manon Ballu, Romain Dubessy, Aurélien Perrin +2
We study the out-of-equilibrium dynamics of a weakly interacting one-dimensional Bose gas in a box trap, subjected to a drive realized by a periodically oscillating linear potentia…
Microwave spectroscopy of ultracold-sodium least-bound molecular states
Manon Ballu, Zhibin Yao, Bastien Mirmand +3
We have performed microwave spectroscopy of sodium least-bound molecular states, improving the precision of the knowledge of their energies at zero magnetic field by almost three o…
Fast manipulation of a quantum gas on an atom chip with a strong microwave field
Manon Ballu, Bastien Mirmand, Thomas Badr +2
We report on an experimental platform based on an atom chip encompassing a coplanar waveguide which enables the manipulation of a quantum gas of sodium atoms with strong microwave…
Thermal melting of a vortex lattice in a quasi two-dimensional Bose gas
Rishabh Sharma, David Rey, Laurent Longchambon +3
We report the observation of the melting of a vortex lattice in a fast rotating quasi-two dimensional Bose gas, under the influence of thermal fluctuations. We image the vortex lat…
