WallGo investigates: Theoretical uncertainties in the bubble wall velocity
Jorinde van de Vis, Philipp Schicho, Lauri Niemi +3
We examine theoretical uncertainties in state-of-the-art calculations of the bubble wall velocity during first-order cosmological phase transitions. By utilising the software WallG…
Bounds on the bubble wall velocity
Wen-Yuan Ai, Benoit Laurent, Jorinde van de Vis
Determining the bubble wall velocity in first-order phase transitions is a challenging task, requiring the solution of (coupled) equations of motion for the scalar field and Boltzm…
Higgs Inflation as Nonlinear Sigma Model and Scalaron as its -meson
Yohei Ema, Kyohei Mukaida, Jorinde van de Vis
We point out that a model with scalar fields with a large nonminimal coupling to the Ricci scalar, such as Higgs inflation, can be regarded as a nonlinear sigma model (NLSM). With…
Nonlinear Dynamics of Preheating after Multifield Inflation with Nonminimal Couplings
Rachel Nguyen, Jorinde van de Vis, Evangelos I. Sfakianakis +2
We study the post-inflation dynamics of multifield models involving nonminimal couplings using lattice simulations to capture significant nonlinear effects like backreaction and re…
