Notes on the Quantum Corrections of Swampland and Trans-Planckian Censorship Conjecture

TL;DR

This paper examines quantum corrections to the de Sitter swampland and trans-Planckian censorship conjectures, highlighting that TCC remains stable while bounds on the swampland can be relaxed by quantum effects.

Contribution

It introduces quantum corrections to entropy bounds and energy conditions, providing new insights into the stability of these conjectures in quantum regimes.

Findings

TCC remains largely unaffected by quantum corrections.

Quantum effects can relax bounds on the de Sitter swampland conjecture.

Entanglement entropy plays a significant role in quantum corrections.

Abstract

We discuss the de Sitter swampland and trans-Planckian censorship conjectures (TCC) from the entropy bound with quantum corrections, namely quantum version of Bousso bound and energy conditions. We include the typical contributions from the entanglement entropy in quasi-de Sitter spacetime. The TCC is not much corrected, whereas the bounds on de Sitter swampland conjecture from energy conditions can be relaxed due to quantum corrections.
