How to measure the free energy and partition function from atom-atom correlations

ML Kerr, KV Kheruntsyan - Physical Review A, 2024 - APS
We propose an experimental approach for determining thermodynamic properties of
ultracold atomic gases with short-range interactions. As a test case, we focus on the one …

Simulating cosmological supercooling with a cold-atom system

TP Billam, K Brown, IG Moss - Physical Review A, 2020 - APS
We perform an analysis of the supercooled state in an analog to an early universe phase
transition based on a one-dimensional, two-component Bose gas. We demonstrate that the …

Enhanced transport of spin-orbit-coupled Bose gases in disordered potentials
