# Thermodynamics of Ricci-Gauss-Bonnet Dark Energy

## TL;DR

This paper examines the generalized second law of thermodynamics within a flat FRW universe containing Ricci-Gauss-Bonnet dark energy and cold dark matter, analyzing various entropy corrections on different horizons.

## Contribution

It introduces the study of thermodynamic laws for Ricci-Gauss-Bonnet dark energy with multiple entropy corrections on apparent and event horizons.

## Key findings

- The generalized second law holds on both horizons for most entropy corrections.
- Logarithmic correction violates the law at the apparent horizon.
- Thermodynamic equilibrium is maintained across all cases.

## Abstract

We investigate the validity of generalized second law of thermodynamics of a physical system comprising of newly proposed dark energy model called Ricci Gauss-Bonnet and cold dark matter enveloped by apparent horizon and event horizon in flat Friedmann-Robertson-Walker (FRW) universe. For this purpose, Bekenstein entropy, Renyi, logarithmic and power law entropic corrections are used. It is found that this law exhibits the validity on both apparent and event horizons except for the case of logarithmic entropic correction at apparent horizon. Also, we check the thermodynamical equilibrium condition for all cases of entropy and found its vitality in all cases of entropy.
