The hot early Universe must have evolved through phase transitions around the electroweak epoch. In multi-Higgs models, this evolution could be much more intricate than a single-step EWPT. In this talk, I will discuss a peculiar regime in the two-Higgs-doublet model, in which thermal evolution of the early Universe passes through an intermediate phase with a charge-breaking vacuum. Remarkably,...
