# Holographic correspondence of $F(R)$ gravity with/without matter fields

## TL;DR

This paper explores the holographic correspondence of various F(R) and F(T) gravity models, including matter fields, demonstrating their viability for inflation consistent with Planck 2018 data.

## Contribution

It establishes a holographic correspondence for extended F(R) and F(T) gravity models with matter fields, including Kalb-Ramond fields, and shows their inflationary viability.

## Key findings

- Holographic correspondence exists for various F(R) models without matter.
- Correspondence extends to models with matter fields, including Kalb-Ramond.
- Models are consistent with Planck 2018 inflation constraints.

## Abstract

In this paper, we apply the holographic principle at the early universe, obtaining an inflation realization of holographic origin. First we show that under the consideration of extended infrared cut-offs, there exist a holographic correspondence of various F(R) (such as quadratic, cubic, exponential F(R) models) cosmological models in absence of matter fields. Then we establish that such holographic correspondence is not only confined to the vacuum F(R) gravity but also can be extended to the higher curvature models along with matter fields. In presence of matter field, in particular the second rank antisymmetric Kalb-Ramond field, all the considered F(R) models lead to a viable inflationary phenomenology consistent with Planck 2018 constraints. We further extend our discussion of holographic correspondence to F(T) cosmological models.
