Cooling a strongly-interacting quantum gas by interaction modulation
Daniel Eberz, Andreas Kell, Moritz Breyer +1
We present a cooling method for a strongly-interacting trapped quantum gas. By applying a magnetic field modulation with frequencies close to the binding energy of a molecular boun…
Exciting the Higgs mode in a strongly-interacting Fermi gas by interaction modulation
Andreas Kell, Moritz Breyer, Daniel Eberz +1
We study the Higgs mode of a strongly-interacting Fermi gas in the crossover regime between a fermionic and bosonic superfluid. By periodically modulating the interaction strength…
Machine-learning the phase diagram of a strongly-interacting Fermi gas
M. Link, K. Gao, A. Kell +4
We determine the phase diagram of strongly correlated fermions in the crossover from Bose-Einstein condensates of molecules (BEC) to Cooper pairs of fermions (BCS) utilizing an art…
Detecting the phase transition in a strongly-interacting Fermi gas by unsupervised machine learning
D. Eberz, M. Link, A. Kell +3
We study the critical temperature of the superfluid phase transition of strongly-interacting fermions in the crossover regime between a Bardeen-Cooper-Schrieffer (BCS) superconduct…
