A Hubble-induced phase transition is a natural spontaneous symmetry breaking mechanism allowing for explosive particle production in non-oscillatory models of inflation involving non-minimally coupled spectator fields. I will discuss the impact of this effect on the reheating of the Universe after inflation and its characterization via 3+1-dimensional classical lattice simulations, discussing...
Domain walls are a type of topological defects that can arise in the
early universe after the spontaneous breaking of a discrete symmetry. This occurs in several beyond Standard Model theories with an
extended Higgs sector such as the Next-to-Two-Higgs-Doublet model
(N2HDM). In this talk I will discuss the domain wall solution related
to the singlet scalar of the N2HDM as well as...
We present a detailed study of the precision calculations of higher-order contributions to effective potential with the application of three-dimensional effective field theories (3D EFTs). Our work focuses on the thermodynamic quantification and description of electroweak phase transitions in the early Universe for the complex singlet extended Standard Model (cxSM). In particular, we address...
