Non-extremal island in de Sitter gravity

Non-extremal island in de Sitter gravity

Abstract This paper investigates the challenges and resolutions in computing the entanglement entropy for the quantum field theory coupled to de Sitter (dS) gravity along a timelike boundary. The conventional island formula, originally designed to calculate the fine-grained entropy for a non-gravita...
