Infinite Temperature is Not So Infinite: The Many Temperatures of de Sitter Space

High Energy Physics - Theory 2025-04-18 v3 General Relativity and Quantum Cosmology

Abstract

Several distinct concepts of temperature appear in the holographic description of de Sitter space. Conflating these has led to confusion and inconsistent claims. The double-scaled limit of SYK is a concrete model in which we can examine and explain these different concepts of temperature. This note began as an addendum to our paper ``Comments on a Paper by Narovlansky and Verlinde" but in the process of writing it we learned new things -- interesting in their own right -- that we wish to report here.
