A Notion of Entropy for Causal Fermion Systems
arXiv:2103.14980 · doi:10.1007/s11005-021-01467-1
Abstract
A notion of entropy is introduced for causal fermion systems. This entropy is a measure of the state of disorder of a causal fermion system at a given time compared to the vacuum. The definition is given both in the finite and infinite-dimensional settings. General properties of the entropy are analyzed.
