Holographic Cosmology from a System of M2-M5 Branes

TL;DR

This paper explores holographic cosmology through M2-M5 brane configurations, proposing a model where brane interactions drive cosmic inflation and subsequent acceleration phases.

Contribution

It introduces a novel M2-M5 brane setup to model inflation and late-time acceleration in holographic cosmology.

Findings

Brane interactions induce inflationary expansion.

Separation of branes ends inflation.

Reconnection via tachyonic states causes further acceleration.

Abstract

In this paper, we analyze the holographic cosmology using a M2-M5 brane configuration. In this configuration, a M2-brane will be placed in between a M5-brane and an anti-M5-brane. The M2-brane will act as a channel for energy to flow from an anti-M5-brane to a M5-brane, and this will increase the degrees of freedom on the M5-brane causing inflation. The inflation will end when the M5-brane and anti-M5-brane get separated. However, at a later stage the distance between the M5-brane and the anti-M5-bran can reduce and this will cause the formation of tachyonic states. These tachyonic states will be again open a bridge between the M5-branes and the anti-M5-branes, which will cause further acceleration of the universe.
