Numerical calculations of the decay rate of a false vacuum for a modified quartic potential
The possibility of two or more vacuum states with different energy densities is a common feature of many potentials. The classical state is in stable equilibrium at any of these minima but is made unstable by quantum effects. The formalism that describes transitions from a false (higher energy …

Probes of cosmic inflation: from the CMB to quantum analogues
… part of the thesis investigates the dynamics of false vacuum decay (FVD), a first-order phase transition at the heart of the eternal inflation paradigm. In Chapter 4, we use semiclassical lattice simulations to model the phenomenon in real time and extract ensemble-averaged bubble profiles at the …

Simulation of curved-space quantum field theories with two-component Bose-Einstein condensates: from black-hole physics to cosmology
… we then proceed to tackle a problem (the decay from the false vacuum) which instead requires the additional degrees of freedom that only a mixture displays.
