Models for unitary black hole disintegration

TL;DR

This paper introduces effective Hilbert-space models for unitary black hole evolution, exploring minimal locality relaxation to reconcile black hole dynamics with quantum unitarity.

Contribution

It proposes simple, effective models that minimally relax locality constraints to describe unitary black hole disintegration.

Findings

Models demonstrate potential for unitary evolution consistent with black hole physics.

Relaxation of locality is minimal yet sufficient for unitarity.

Framework provides a basis for further exploration of black hole information paradox.

Abstract

Simple models for unitary black hole evolution are given in an effective Hilbert-space description, parameterizing a possible minimal relaxation of locality, with respect to semiclassical black hole geometry.
