Dimensional deformation of sine-Gordon breathers into oscillons
José T. Gálvez Ghersi, Jonathan Braden
Oscillons are localized field configurations oscillating in time with lifetimes orders of magnitude longer than their oscillation period. In this paper, we simulate non-travelling…
Mass Renormalization in Lattice Simulations of False Vacuum Decay
Jonathan Braden, Matthew C. Johnson, Hiranya V. Peiris +2
False vacuum decay, a quantum mechanical first-order phase transition in scalar field theories, is an important phenomenon in early universe cosmology. Recently, real-time semi-cla…
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…
Nonlinear Dynamics of the Cold Atom Analog False Vacuum
Jonathan Braden, Matthew C. Johnson, Hiranya V. Peiris +2
We investigate the nonlinear dynamics of cold atom systems that can in principle serve as quantum simulators of false vacuum decay. The analog false vacuum manifests as a metastabl…
A New Semiclassical Picture of Vacuum Decay
Jonathan Braden, Matthew C. Johnson, Hiranya V. Peiris +2
We introduce a new picture of vacuum decay which, in contrast to existing semiclassical techniques, provides a real-time description and does not rely on classically-forbidden tunn…
Towards the cold atom analog false vacuum
Jonathan Braden, Matthew C. Johnson, Hiranya V. Peiris +1
Analog condensed matter systems present an exciting opportunity to simulate early Universe models in table-top experiments. We consider a recent proposal for an analog condensed ma…
