Nambu Goto cosmic strings in the early universe
S Sanyal - The European Physical Journal Special Topics, 2022 - Springer
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 …

Baryon inhomogeneity generation in the quark-gluon plasma phase
We discuss the possibility of generation of baryon inhomogeneities in a quark-gluon plasma
phase due to moving Z (3) interfaces. By modeling the dependence of effective mass of the …

Diffusion of massive particles around an Abelian-Higgs string
We study the diffusion of massive particles in the space time of an Abelian Higgs string. The
particles in the early universe plasma execute Brownian motion. This motion of the particles …

Diffusion coefficients and constraints on hadronic inhomogeneities in the early universe
Hadronic inhomogeneities are formed after the quark hadron phase transition. The nature of
the phase transition dictates the nature of the inhomogeneities formed. Recently some …

[HTML][HTML] Decay of baryon inhomogeneities in an expanding universe
Baryon inhomogeneities are generated early in the universe. These inhomogeneities affect
the phase transition dynamics of subsequent phase transitions, they also affect the …

Isocurvature fluctuations through axion trapping by cosmic string wakes
B Layek - Physical Review D—Particles, Fields, Gravitation, and …, 2005 - APS
We consider wakelike density fluctuations produced by cosmic strings at the quark-hadron
transition in the early universe. We show that low momentum axions which are produced …
