Area spectrum of the D-dimensional de Sitter spacetime

TL;DR

This paper investigates whether the quantum area spectrum of D-dimensional de Sitter horizons can be derived from asymptotic quasinormal frequencies, extending methods used for black holes.

Contribution

It applies and tests the quasinormal mode approach to the de Sitter horizon in D dimensions, integrating thermodynamic insights from Padmanabhan and previous frequency analyses.

Findings

Provides a framework for quantizing de Sitter horizon area

Extends quasinormal frequency methods beyond black holes

Connects thermodynamics with quantum horizon spectra

Abstract

The determination of the quantum area spectrum of a black hole horizon by means of its asymptotic quasinormal frequencies has been explored recently. We believe that for D-dimensional de Sitter horizon we must study if the idea works. Thus taking into account the local description of the thermodynamics of horizons proposed by Padmanabhan and the results of Hod, Kunstatter, and Maggiore we study the area spectrum of the D-dimensional de Sitter horizon.
