Infinite Temperature is Not So Infinite: The Many Temperatures of de Sitter Space
arXiv:2401.08555
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.
