Path Integral Factorization and the Gravitational Effective Action
Patrick Draper, Szilard Farkas, Manthos Karydas
We discuss the factorization and continuity properties of fields in the Euclidean gravitational path integral with higher dimension operators constructed from powers of the Riemann…
de Sitter Black Holes as Constrained States in the Euclidean Path Integral
Patrick Draper, Szilard Farkas
Schwarzschild-de Sitter black holes have two horizons that are at different temperatures for generic values of the black hole mass. Since the horizons are out of equilibrium the so…
Euclidean de Sitter Black Holes and Microcanonical Equilibrium
Patrick Draper, Szilard Farkas
Schwarzschild-de Sitter (SdS) black holes do not admit a completely smooth Euclidean continuation. We discuss some modifications of the gravitational path integral that give Euclid…
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…
Transplanckian Censorship and the Local Swampland Distance Conjecture
Patrick Draper, Szilard Farkas
The swampland distance conjecture (SDC) addresses the ability of effective field theory to describe distant points in moduli space. It is natural to ask whether there is a local ve…
