The Fermionic Entanglement Entropy of Causal Diamonds in Two-Dimensional Minkowski Space
Felix Finster, Magdalena Lottner, Albert Much +1
The fermionic Rényi entanglement entropy is studied for causal diamonds in two-dimensional Minkowski spacetime. Choosing the quasi-free state describing the Minkowski vacuum with…

Notions of Fermionic Entropies of a Causal Fermion System
Felix Finster, Robert H. Jonsson, Magdalena Lottner +2
The fermionic von Neumann entropy, the fermionic entanglement entropy and the fermionic relative entropy are defined for causal fermion systems. Our definition makes use of entropy…
