A connected-cluster survival criterion in real-time lattice simulations yields false vacuum decay rates that match Hartree-resummed thermal benchmarks at high temperatures and converge with global-survival methods at low temperatures in the dilute regime.

abstract
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.

Evidence for renormalized instantons in real-time simulations of vacuum decay
Ensemble-averaged bubble profiles and decay rates from zero-temperature lattice simulations match Coleman instantons computed in a one-parameter renormalized effective potential, not the bare potential.
