The art of simulating the early Universe. Part III: Scalar-Gauge-Fluid Dynamics
Daniel G. Figueroa, Kenneth Marschall, Antonino S. Midiri +1
The paper reviews lattice-based methods for simulating fluid dynamics in the early Universe, including how fluids couple to scalar and gauge fields and how to set up initial condit…
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…
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,…
LISA and -ray telescopes as multi-messenger probes of a first-order cosmological phase transition
A. Roper Pol, A. Neronov, C. Caprini +2
We study two possible cosmological consequences of a first-order phase transition in the temperature range of 1 GeV to TeV: the generation of a stochastic gravitational wave…
Primordial magnetic field from chiral plasma instability with sourcing
Murman Gurgenidze, Andrew J. Long, Alberto Roper Pol +2
In an electron-positron plasma, an imbalance in the number of right- and left-chiral particles can lead to the growth of a helical magnetic field through a phenomenon called the ch…
Gravitational wave spectra for cosmological phase transitions with non-linear decay of the fluid motion
Isak Stomberg, Alberto Roper Pol
We summarize the theoretical framework of gravitational wave (GW) production by bulk fluid motion induced by expanding broken-phase bubbles during a first-order phase transition. U…
