A principle of maximum ignorance for semiclassical gravity

J de Boer, D Liska, B Post, M Sasieta - Journal of High Energy Physics, 2024 - Springer
A bstract The principle of maximum ignorance posits that the coarse-grained description of a
system is maximally agnostic about its underlying microscopic structure. We briefly review …
