Information Retrieval from a Charge `Trap'

TL;DR

This paper investigates how information and charge behave in a 1+1 dimensional electrodynamics model with a nonconstant coupling, mimicking black hole structure, revealing charge and information separation during the process.

Contribution

It introduces a novel boundary configuration in the charge trap model to study charge and information dynamics in a black hole-like setting.

Findings

Charge and information separate during the process.

Charge exits near the singularity endpoint.

Information follows a localized path through the strong coupling region.

Abstract

We study the model of massless $1+1$ electrodynamics with nonconstant coupling, introduced by Peet, Susskind and Thorlacius as the `charge hole'. But we take the boundary of the strong coupling region to be first timelike, then spacelike for a distance $X$, and then timelike again (to mimic the structure of a black hole). For an incident charge pulse entering this `charge trap' the charge and information get separated. The charge comes out near the endpoint of the singularity. The `information' travels a well localised path through the strong coupling region and comes out later.
