Evidence for renormalized instantons in real-time simulations of vacuum decay
Emilie Hertig, Alexander C. Jenkins, Hiranya V. Peiris +2
While vacuum decay is traditionally described by Euclidean instanton methods, lattice simulations enable real-time modeling of dynamical observables relevant to cosmology and upcom…

Analog Simulation of Massive Relativistic Quantum Fields in 2 + 1 Dimensions
Yansheng Zhang, Feiyang Wang, Paul H. C. Wong +8
Quantum field theories provide fundamental models of complex interacting systems, from high-energy physics and cosmology to condensed matter. However, solving these models in non-p…

Bubbles in a box: Eliminating edge nucleation in cold-atom simulators of vacuum decay
Alexander C. Jenkins, Hiranya V. Peiris, Andrew Pontzen
The decay of metastable 'false vacuum' states via bubble nucleation plays a crucial role in many cosmological scenarios. Cold-atom analog experiments will soon provide the first em…
