A tale of two timescales: Mixing, mass generation, and phase transitions in the early universe [PDF]
, 2016 Light scalar fields such as axions and string moduli can play an important role in early-universe cosmology. However, many factors can significantly impact their late-time cosmological abundances.

Kaluza-Klein towers in the early universe: Phase transitions, relic abundances, and applications to axion cosmology [PDF]
, 2017 We study the early-universe cosmology of a Kaluza-Klein (KK) tower of scalar fields in the presence of a mass-generating phase transition, focusing on the time-development of the total tower energy density (or relic abundance) as well as its distribution

Have pulsar timing arrays detected the hot big bang: Gravitational waves from strong first order phase transitions in the early Universe [PDF]
Physical Review D, 2022 The origins of matter and radiation in the universe lie in a Hot Big Bang. We present a number of well-motivated cosmologies in which the Big Bang occurs through a strong first order phase transition – either at the end of inflation, after a period of ...

Probing Early Universe Supercooled Phase Transitions with Gravitational Wave Data [PDF]
Physical Review D, 2022 We investigate the reach of the LIGO/Virgo/KAGRA detectors in the search for signatures of first-order phase transitions in the early Universe. Utilising data from the first three observing runs, we derive constraints on the parameters of the underlying ...

Spontaneous symmetry breaking in the late Universe and glimpses of early Universe phase transitions à la baryogenesis [PDF]
International Journal of Modern Physics D, 2021 Spontaneous symmetry breaking is the foundation of electroweak unification and serves as an integral part of the model building beyond the standard model of particle physics and it also finds interesting applications in the late Universe.

The formation of primary galactic nuclei during phase transitions in the early universe [PDF]
, 2001 A new mechanism describing the formation of protogalaxies is proposed, based on the second-order phase transition in the inflation stage and the domain wall formation upon the end of inflation.

Thermal suppression of bubble nucleation at first-order phase transitions in the early Universe [PDF]
Physical Review D, 2022 One of the key observables in a gravitational wave power spectrum from a first order phase transition in the early Universe is the mean bubble spacing, which depends on the rate of nucleation of bubbles of the stable phase, as well as the bubble wall ...

Quark-hadron phase transitions in the viscous early universe [PDF]
, 2012 In the standard hot big bang theory, when the Universe was about 1 10 s old, the cosmological matter is conjectured to undergo Quantum Chromodynamics (QCD) phase transition(s) from quark matter to hadrons.

Reconstructing early universe evolution with gravitational waves from supercooled phase transitions [PDF]
Journal of High Energy PhysicsWe study gravitational waves from supercooled cosmological first-order phase transitions. If such a transition is followed by inefficient reheating, the evolution history of the universe is modified by a period of early matter domination.
