Contribution

It introduces a unified analysis of GUP and MDR effects on early universe thermodynamics, highlighting their combined influence on cosmological models.

Findings

GUP and MDRs modify the thermodynamic behavior of early universe particles.

Measurement limitations due to GUP affect cosmological horizon physics.

Alterations suggest new insights into early universe evolution.

Abstract

In this paper, we study the effects of Generalized Uncertainty Principle(GUP) and Modified Dispersion Relations(MDRs) on the thermodynamics of ultra-relativistic particles in early universe. We show that limitations imposed by GUP and particle horizon on the measurement processes, lead to certain modifications of early universe thermodynamics.
