Phase transitions in the early universe [PDF]
, 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

Probing early Universe supercooled phase transitions with gravitational wave data
, 2023 We investigate the reach of the LIGO/Virgo/KAGRA detectors in the search for signatures of first-order phase transitions in the early Universe. Utilizing data from the first three observing runs, we derive constraints on the parameters of the underlying ...

Thermal suppression of bubble nucleation at first-order phase transitions in the early Universe [PDF]
, 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 ...

Phase transitions and topological defects in the early universe [PDF]
, 1997 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 ...

Phase transitions and the birth of early universe particle physics [PDF]
, 2023 This paper provides a conceptual history of the development of early universe particle physics in the 1970s, focusing on the development of more sophisticated tools for constructing gauge-theories at finite- temperature.

Vortex line nucleation of first-order phase transitions in early universe [PDF]
, 2020 With nonabelian Gauge Theories apparently possessing an abelian projection, the first-order phase transitions in the early Ž . universe should proceed similarly to those in U 1 -symmetric field systems, where they are known to be nucleated by vortex ...

Probing phase transitions in the early universe with gravitational waves
, 2022 Gravitational waves will be an important probe of physics beyond the Standard Model, as they would be produced at possible first order phase transitions in the early universe. I will discuss the characteristic spectrum of gravitational radiation ...

Phase transitions in single neurons and neural populations: Critical slowing, anesthesia, and sleep cycles [PDF]
, 2010 The firing of an action potential by a biological neuron represents a dramatic transition from small-scale linear stochastics (subthreshold voltage fluctuations) to gross-scale nonlinear dynamics (birth of a 1-ms voltage spike). In populations of neurons

The stability of primordial magnetic fields produced by phase transitions [PDF]
, 1995 Primordial magnetic fields seem to be a generic relic of phase transitions in the early universe. We consider a primordial electromagnetic field formed as a result of a second-order phase transition, and show that it is stable to thermal fluctuations in ...

Nambu Goto cosmic strings in the early universe
, 2021 In this brief review, I discuss some of the effects of the Nambu Goto cosmic strings in the early universe. Nambu Goto strings are formed from symmetry breaking phase transitions in the early universe.
