Project level: Honours

Thermal effects after inflation can cause the Universe to 'jump' from one vacuum to another. Depending on what the vacua look like, and how hot the Universe gets after inflation (i.e. the 'reheating temperature'), this is more or less likely. The project will look at what bounds this places on the reheating temperature for some simple but viable beyond-the-Standard Model particle theories possessing multiple minima in their potential, namely Type II/III/X/Y Two-Higgs Doublet Models.
