Path Integrals for Causal Diamonds and the Covariant Entropy Principle
Tom Banks, Patrick Draper, Szilard Farkas
We study causal diamonds in Minkowski, Schwarzschild, (anti) de Sitter, and Schwarzschild-de Sitter spacetimes using Euclidean methods. The null boundaries of causal diamonds are s…

Does causal dynamics imply local interactions?
Zoltán Zimborás, Terry Farrelly, Szilárd Farkas +1
We consider quantum systems with causal dynamics in discrete spacetimes, also known as quantum cellular automata (QCA). Due to time-discreteness this type of dynamics is not charac…
