The art of simulating the early Universe. Part III: Scalar-Gauge-Fluid Dynamics
Daniel G. Figueroa, Kenneth Marschall, Antonino S. Midiri +1
We discuss lattice methods for the simulation of fluid dynamics in the early Universe. This review represents a third entry in the monographic series on lattice cosmology technique…

Fluid perturbations from expanding bubbles in first-order phase transitions
Chiara Caprini, Antonino S. Midiri, Simona Procacci +1
We study the power spectrum of the velocity field induced during a first-order phase transition occurring in the radiation-dominated era. We focus on the phase of bubble expansion,…

Relativistic magnetohydrodynamics in the early Universe
Alberto Roper Pol, Antonino Salvino Midiri
We review the conservation laws of magnetohydrodynamics (MHD) in an expanding homogeneous and isotropic Universe that can be applied to the study of early Universe physics during t…
