Photon-mediated thermodynamics and density fluctuations in an ensemble of laser-cooled Cesium atoms
Arnab Ghosh, Inderpreet Kaur, Hemant Yadav +5
We present an experimental study of detuning-dependent properties of a laser-cooled cesium cloud in a magneto-optical trap. Fluorescence images are used to extract the cloud size,…
Nonequilibrium Transport in a Superfluid Josephson Junction Chain: Is There Negative Differential Conductivity?
Samuel E. Begg, Matthew J. Davis, Matthew T. Reeves
We consider the far-from-equilibrium quantum transport dynamics in a 1D Josephson junction chain of multi-mode Bose-Einstein condensates. We develop a theoretical model to examine…
Optimizing persistent currents in a ring-shaped Bose-Einstein condensate using machine learning
Simeon Simjanovski, Guillaume Gauthier, Matthew J. Davis +2
We demonstrate a method for generating persistent currents in Bose-Einstein condensates by using a Gaussian process learner to experimentally control the stirring of the superfluid…
Many-body enhancement in a spin-chain quantum heat engine
L. A. Williamson, Matthew J. Davis
We show that ferromagnetic interactions can enhance the adiabatic performance of a quantum spin chain engine at low temperatures. The enhancement in work output is particular prono…
Viability of rotation sensing using phonon interferometry in Bose-Einstein condensates
Charles W. Woffinden, Andrew J. Groszek, Guillaume Gauthier +7
We demonstrate the use of a ring-shaped Bose-Einstein condensate as a rotation sensor by measuring the interference between two counter-propagating phonon modes imprinted azimuthal…
Dynamical mechanisms of vortex pinning in superfluid thin films
Oliver R. Stockdale, Matthew T. Reeves, Matthew J. Davis
We characterize the mechanisms of vortex pinning in a superfluid thin film described by the two-dimensional Gross-Pitaevskii equation. We consider a vortex "scattering experiment"…
