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…

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 a…
