On the TransPlanckian Censorship Conjecture in Holographic Cosmology

TL;DR

This paper explores the implications of the TransPlanckian Censorship Conjecture for holographic cosmology, deriving bounds on RG flow and energy scales, and addressing the transPlanckian problem in non-geometrical models.

Contribution

It introduces bounds on coupling running and energy scales in holographic inflation models consistent with the TCC, and discusses the transPlanckian problem in non-geometrical holography.

Findings

Bound on the running of the field theory coupling

Maximum energy scale for RG flow modification

Discussion on transPlanckian problem in non-geometrical models

Abstract

In this letter we discuss the implications of the recently proposed TransPlanckian Censorship Conjecture (TCC) for Holographic Cosmology. For models of holographic inflation that are dual to inverse renormalization group (RG) flows, assuming the TCC to be true, we found a bound on the running of the field theory coupling and the corresponding maximum energy scale above which the RG flow should be modified. We also discuss on the transPlanckian problem in non-geometrical holographic models.
