Nonlinear dynamics of coupled superfluids
S Laurent, P. Parnaudeau, F. Chevy +1
Following recent experiments on ultracold dual superflows, we model in this work the dynamics of two harmonically trapped counterflowing superfluids. Using complementary analytical…
Connecting few-body inelastic decay to many-body correlations: a weakly coupled impurity in a resonant Fermi gas
Sébastien Laurent, Matthieu Pierce, Marion Delehaye +3
We study three-body recombination in an ultracold Bose-Fermi mixture. We first show theoretically that, for weak inter-species coupling, the loss rate is proportional to Tan's cont…
Critical Velocity and Dissipation of an ultracold Bose-Fermi Counterflow
Marion Delehaye, Sébastien Laurent, Igor Ferrier-Barbut +3
We study the dynamics of counterflowing bosonic and fermionic lithium atoms. First, by tuning the interaction strength we measure the critical velocity vc of the system in the BEC-…
Universal Loss Dynamics in a Unitary Bose Gas
Ulrich Eismann, Lev Khaykovich, Sébastien Laurent +8
The low temperature unitary Bose gas is a fundamental paradigm in few-body and many-body physics, attracting wide theoretical and experimental interest. Here we first present a the…
Momentum distribution of a dilute unitary Bose gas with three-body losses
Sébastien Laurent, Xavier Leyronas, Frédéric Chevy
Using Boltzmann's equation, we study the effect of three-body losses on the momentum distribution of a homogeneous unitary Bose gas in the dilute limit where quantum correlations a…
