Analog vacuum decay from vacuum initial conditions
Alexander C. Jenkins, Jonathan Braden, Hiranya V. Peiris +3
Ultracold atomic gases can undergo phase transitions that mimic relativistic vacuum decay, allowing us to empirically test early-Universe physics in tabletop experiments. We invest…
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…
enics: Vainshtein screening with the finite element method
Jonathan Braden, Clare Burrage, Benjamin Elder +1
Within the landscape of modified theories of gravity, progress in understanding the behaviour of, and developing tests for, screening mechanisms has been hindered by the complexity…
The Impact of Peculiar Velocities on the Estimation of the Hubble Constant from Gravitational Wave Standard Sirens
Constantina Nicolaou, Ofer Lahav, Pablo Lemos +2
In this work we investigate the systematic uncertainties that arise from the calculation of the peculiar velocity when estimating the Hubble constant () from gravitational wav…
