First Order Phase Transitions in a Bianchi type-I universe [PDF]
, 2000 Considering the theory of induced gravity coupled to matter fields, taking the $\phi ^6$ interaction potential model we evaluate the one-loop effective potential in a (3+1)dimensional Bianchi type-I spacetime.

Quark-hadron phase transitions in the viscous early universe [PDF]
Physical Review D, 2012 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.

Primordial Black Hole Formation during First-Order Phase Transitions [PDF]
, 1999 Primordial black holes (PBHs) may form in the early universe when pre-existing adiabatic density fluctuations enter into the cosmological horizon and recollapse. It has been suggested that PBH formation may be facilitated when fluctuations enter into the

Finite-Size Effects on Nucleation in a First-Order Phase Transition [PDF]
, 2003 We discuss finite-size effects on homogeneous nucleation in first-order phase transitions. We study their implications for cosmological phase transitions and to the hadronization of a quark-gluon plasma generated in high-energy heavy ion collisions. Very

Quark-Gluon Plasma in the Early Universe [PDF]
, 2001 A QCD phase transition in the early universe could have left inhomogeneities in the baryon to photon ratio and in isospin that might have affected nucleosynthesis later on.

Inflationary Gravitational Waves and the Evolution of the Early Universe [PDF]
, 2013 We study the effects of various phenomena which may have happened in the early universe on the spectrum of inflationary gravitational waves. The phenomena include phase transitions, entropy productions from non-relativistic matter, the production of dark

Phase transitions in the early universe
, 2023 Phase transitions are a generic prediction of models in particle physics. In the Standard Model, for example, there are two phase transitions: the QCD confinement transition and the electroweak phase transition, both occurring in the very early stages of the universe. Many extensions to the Standard Model predict new phase transitions, all occurring at

SUPERCOOLING AND NUCLEATION IN PHASE TRANSITIONS OF THE EARLY UNIVERSE [PDF]
Modern Physics Letters A, 1996 The three phase transitions (the GUT, the electroweak and the quark-hadron), which the universe is assumed to have undergone, produce very important physical effects if they are assumed to be of first-order. It is also important that enough supercooling is produced at these transitions so that the rate of nucleation of the lower temperature phase out ...

Phase Transitions in the Universe [PDF]
, 1998 During the past two decades, cosmologists turned to particle physics in order to explore the physics of the very early Universe. The main link between the physics of the smallest and largest structures in the Universe is the idea of spontaneous symmetry ...
