Quark-hadron phase transitions in the viscous early universe [PDF]
Based on hot big bang theory, the cosmological matter is conjectured to undergo QCD phase transition(s) to hadrons, when the universe was about $1-10 $s old. In the present work, we study the quark-hadron phase transition, by taking into account the effect of the bulk viscosity.

Phase Transitions in the Early Universe and Defect Formation [PDF]
In the first one of these two lectures, I give an introductory review of phase transitions in finite temperature field theories. I highlight the differences between theories with global and local symmetries, and the similarities between cosmological phase transitions and phase transitions in superconductors.

A Little Inflation in the Early Universe at the QCD Phase Transition [PDF]
We explore a scenario that allows for a strong first order phase-transition of QCD at non-negligible baryon number in the early universe and its possible cosmological observable consequences. The main assumption is a quasi-stable QCD-vacuum state that leads to a short period of inflation, consequently diluting the net baryon to photon ratio to it's ...

A tale of two timescales: Mixing, mass generation, and phase transitions in the early universe [PDF]
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.

Phase Transitions and Topological Defects in the Early Universe [PDF]
Our present theories of particle physics and cosmology, taken together, suggest that very early in its history, the universe underwent a series of phase transitions, at which topological defects, similar to those formed in some condensed matter transitions, may have been created.

Reconstructing early universe evolution with gravitational waves from supercooled phase transitions [PDF]
We 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.

Kaluza-Klein towers in the early universe: Phase transitions, relic abundances, and applications to axion cosmology [PDF]
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
