Title: Island finder and entropy bound

Abstract

Identifying an entanglement island requires exquisite control over the entropy of quantum fields, which is available only in toy models. Here we present a set of sufficient conditions that guarantee the existence of an island and place an upper bound on the entropy computed by the island rule. This is enough to derive the main features of the Page curve for an evaporating black hole in any spacetime dimension. Our argument makes use of Wall’s maximin formulation and the quantum focusing conjecture. As a corollary, we derive a novel entropy bound.

Effective entropy of quantum fields coupled with gravity

Journal Article Dong, Xi ; Qi, Xiao-Liang ; Shangnan, Zhou ; ... - Journal of High Energy Physics (Online)

Entanglement entropy, or von Neumann entropy, quantifies the amount of uncertainty of a quantum state. For quantum fields in curved space, entanglement entropy of the quantum field theory degrees of freedom is well-defined for a fixed background geometry. In this paper, we propose a generalization of the quantum field theory entanglement entropy by including dynamical gravity. The generalized quantity named effective entropy, and its Renyi entropy generalizations, are defined by analytic continuation of a replica calculation. The replicated theory is defined as a gravitational path integral with multiple copies of the original boundary conditions, with a co-dimension-2 brane at themore »« less

On the implications of the Bekenstein bound for black hole evaporation

Journal Article Acquaviva, Giovanni ; Iorio, Alfredo ; Scholtz, Martin - Annals of Physics

Highlights: •The Bekenstein bound may imply that classical spacetimes are emergent. •Similarly, particles deemed to be elementary are “quasi particles”. •Black hole evaporation is then necessarily non unitary in any quantum gravity. •Modified Page curves are produced for simple cases. -- Abstract: We elaborate on the possible impact of the Bekenstein bound on the unitarity of black hole evaporation. As such maximal bound on the entropy of any system may be regarded as due to the existence of entities more elementary than the ordinary ones, and since at our energy scales such fundamental degrees of freedom must organize themselves intomore »« less

Island for gravitationally prepared state and pseudo entanglement wedge

Journal Article Miyaji, Masamichi - Journal of High Energy Physics (Online)

We consider spacetime initiated by a finite-sized initial boundary as a generalization of the Hartle-Hawking no-boundary state. We study entanglement entropy of matter state prepared by such spacetime. We find that the entanglement entropy for large subregion is given either by the initial state entanglement or the entanglement island, preventing the entropy to grow arbitrarily large. Consequently, the entanglement entropy is always bounded from above by the boundary area of the island, leading to an entropy bound in terms of the island. The island I is located in the analytically continued spacetime, either at the bra or the ket partmore »« less

New constraints for holographic entropy from maximin: A no-go theorem

Journal Article Rota, Massimiliano ; Weinberg, Sean J. - Physical Review D

The Ryu-Takayanagi (RT) formula for static spacetimes arising in the AdS/CFT correspondence satisfies inequalities that are not yet proven in the case of the Rangamani-Hubeny-Takayanagi (HRT) formula, which applies to general dynamical spacetimes. Wall’s maximin construction is the only known technique for extending inequalities of holographic entanglement entropy from the static to dynamical case. We show that this method currently has no further utility when dealing with inequalities for five or fewer regions. Despite this negative result, we propose the validity of one new inequality for covariant holographic entanglement entropy for five regions. This inequality, while not maximin provable, ismore »« less

Tunneling between multiple histories as a solution to the information loss paradox

Program Document Chen, Pisin

The information loss paradox associated with black hole Hawking evaporation is an unresolved problem in modern theoretical physics. In a recent brief essay, we revisited the the evolution of the black hole entanglement entropy via the Euclidean path integral (EPI) of the quantum state and allow for the branching of semi-classical histories along the Lorentzian evolution. We posited that there exist at least two histories that contribute to EPI, where one is an information-losing history while the other is information-preserving. At early times, the former dominates EPI, while at late times the latter becomes dominant. By so doing we recoveredmore »« less
