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…

### False vacuum decay in the 1+1 dimensional $\varphi^4$ theory

• Physics
• 2022
The false vacuum is a metastable state that can occur in quantum ﬁeld theory, and its decay was ﬁrst studied semi-classically by Coleman. In this work we consider the 1+1 dimensional ϕ 4 theory,

### Bloch oscillations and the lack of the decay of the false vacuum in a one-dimensional quantum spin chain

• Physics
• 2021
We consider the decay of the false vacuum, realised within a quantum quench into an anti-confining regime of the Ising spin chain with a magnetic field opposite to the initial magnetisation. Although

It is believed that first-order phase transitions occurred in the very early universe when the temperature dropped below the grand-unification and Weinberg-Salam energies. Bubbles of the new,

### Experimental black hole evaporation

It is shown that the same arguments which lead to black-hole evaporation also predict that a thermal spectrum of sound waves should be given out from the sonic horizon in transsonic fluid flow.
