Simulating cosmological supercooling with a cold atom system
  We perform an analysis of the supercooled state in an analogue to an early
universe phase transition based on a one dimensional, two-component Bose gas.
We demonstrate that the thermal fluctuations in the relative phase between the
components are characteristic of a relativistic thermal system. Furthermore, we
demonstrate the equivalence of two different approaches to the decay of the
metastable state: specifically a non-perturbative thermal instanton calculation
and a stochastic Gross--Pitaevskii simulation.
