Theoretical uncertainties in reconstructing model parameters with gravitational waves from supercooled phase transitions
Maciej Kierkla, Marek Lewicki, Philipp Schicho +2
Future interferometers may detect a gravitational-wave (GW) signal from a cosmological first-order phase transition. Reconstructing the underlying particle-physics model from such…

Theoretical consistency and phenomenology of supercooled cosmological phase transitions
Maciej Kierkla
This dissertation investigates a supercooled phase transition (PT) in the early Universe. Using high-temperature dimensional reduction (DR), we compute the NLO thermal bubble nucle…

Finite-temperature bubble nucleation with shifting scale hierarchies
Maciej Kierkla, Philipp Schicho, Bogumila Swiezewska +2
Focusing on supercooled phase transitions in models with classical scale symmetry, we formulate a state-of-the art framework for computing the bubble-nucleation rate, accounting fo…
