Contribution

It introduces a detailed analysis of finite temperature effects in brane cosmology, including one-loop corrections and phase transition behavior, highlighting the role of interaction constants as order parameters.

Findings

Critical temperature depends on scalar-bulk gravity interaction constant

Second order phase transition can occur in early universe scenarios

Finite temperature effects can restore symmetries in brane cosmology

Abstract

Finite temperature effects in brane world cosmology are studied by considering the interaction between scalar field and bulk gravity. One-loop correction to zero-temperature potential is computed by taking into account, interaction of scalar field and bulk gravity. Phase transitions and high temperature symmetry restoration are examined. Critical temperature of phase transitions depends on the interaction constant of the scalar field and bulk gravity, and these constant is an order parameter. Present study can account for second order phase transition in early universe, in brane world cosmological scenario.
