Towards a Holographic Description of Inflation and Generation of Fluctuations from Thermodynamics

TL;DR

This paper explores a holographic entropic force approach to inflation, proposing that thermal fluctuations on a holographic screen can generate scale-invariant perturbations responsible for cosmic microwave background anisotropies and structure formation.

Contribution

It introduces a holographic framework for inflation where thermal fluctuations produce observable cosmological perturbations, linking thermodynamics and holography to early universe dynamics.

Findings

Holographic description of inflationary background dynamics.

Thermal fluctuations generate scale-invariant scalar perturbations.

Potential explanation for CMB anisotropies and structure formation.

Abstract

Recently, Verlinde conjectured that gravity may be an entropic force, arising from thermodynamics on the holographic screen. We investigate the implications of the entropic force formalism for inflationary cosmology. We find the background dynamics of inflation can be dually described in the holographic language. At the perturbation level, two kinds of novel scale invariant scalar fluctuations arise from thermal fluctuations on the holographic screen. These fluctuations can be responsible for CMB anisotropy and structure formation.
