Black Hole Evaporation along Macroscopic Strings

TL;DR

This paper models how macroscopic strings near black holes undergo quantum excitations due to Hawking radiation, leading to energy loss similar to spacetime fields, with the string configuration resembling a random walk.

Contribution

It introduces a quantization framework for macroscopic strings extending from black holes and analyzes their excitation and energy flux during Hawking evaporation.

Findings

String excitations form a thermal bath during black hole evaporation.

Energy flux in string modes approximates that of spacetime field modes.

String configurations resemble a random walk in angular coordinates.

Abstract

We develop the quantization of a macroscopic string which extends radially from a Schwarzschild black hole. The Hawking process excites a thermal bath of string modes that causes the black hole to lose mass. The resulting typical string configuration is a random walk in the angular coordinates. We show that the energy flux in string excitations is approximately that of spacetime field modes.
