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…
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…
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…
Loading a quantum gas from a hybrid dimple trap to a shell trap
David Rey, Simon Thomas, Rishabh Sharma +4
Starting from a degenerate Bose gas in a hybrid trap combining a magnetic quadrupole trap and an attractive optical trap resulting from a focused laser beam, we demonstrate the eff…
Expansion of a quantum gas in a shell trap
Yanliang Guo, Emmanuel Mercado Gutierrez, David Rey +6
We report the observation of the controlled expansion of a two-dimensional quantum gas confined onto a curved shell-shaped surface. We start from the ellipsoidal geometry of a dres…
Dynamical phase diagram of a one dimensional Bose gas in a box with a tunable weak-link: from Bose-Josephson oscillations to shock waves
Abhik Kumar Saha, Romain Dubessy
We study the dynamics of one-dimensional bosons trapped in a box potential, in the presence of a barrier creating a tunable weak-link, thus realizing a one dimensional Bose Josephs…
