Description
Cosmological phase transitions represent drastic energy-release processes theorized to have occurred in the early universe. These transitions may arise during either the thermal expansion phase of the Big Bang or the inflationary epoch, generating distinctive observational signatures. Key consequences include gravitational waves, large-scale structure, primordial black holes, and primordial non-Gaussianity—phenomena potentially observable today. This talk will comprehensively review recent advances in understanding these phase transitions and their phenomenological implications.
