Thermal false vacuum decay in (1+1)-dimensions: Evidence for non-equilibrium dynamics
Dalila Pîrvu, Andrey Shkerin, Sergey Sibiryakov
We numerically study the evolution of a classical real scalar field in dimensions with initial conditions describing thermal fluctuations around a metastable vacuum. We t…
Thermal False Vacuum Decay Is More Than It Seems
Dalila Pîrvu, Andrey Shkerin, Sergey Sibiryakov
We study the decay of a thermally excited metastable vacuum in classical field theory using real-time numerical simulations. We find a significantly lower decay rate than predicted…
Bubble velocities and oscillon precursors in first-order phase transitions
Dalila Pîrvu, Matthew C. Johnson, Sergey Sibiryakov
Metastable `false' vacuum states are an important feature of the Standard Model of particle physics and many theories beyond it. Describing the dynamics of a phase transition out o…
Bubble Clustering in Cosmological First Order Phase Transitions
Dalila Pirvu, Jonathan Braden, Matthew C. Johnson
False vacuum decay in quantum mechanical first order phase transitions is a phenomenon with wide implications in cosmology, and presents interesting theoretical challenges. In the…
Conformally Coupled Scalar in Rotating Black Hole Spacetimes
Finnian Gray, Ian Holst, David Kubiznak +3
We demonstrate separability of conformally coupled scalar field equation in general (off-shell) Kerr-NUT-AdS spacetimes in all dimensions. The separability is intrinsically charact…
