Strings Near a Rindler Or Black Hole Horizon

TL;DR

This paper investigates string behavior near Rindler horizons and black hole horizons, revealing a Hagedorn transition at certain temperatures, extending previous research with orbifold techniques.

Contribution

It extends earlier work by applying orbifold methods to analyze string thermodynamics near horizons at multiple temperature multiples, highlighting the occurrence of a Hagedorn transition.

Findings

Hagedorn transition occurs near horizons for all N>1

Orbifold techniques effectively analyze strings in Rindler and black hole backgrounds

Results extend previous studies of string thermodynamics in curved spacetime

Abstract

Orbifold techniques are used to study bosonic, type II and heterotic strings in Rindler space at integer multiples N of the Rindler temperature, and near a black hole horizon at integer multiples of the Hawking temperature, extending earlier results of Dabholkar. It is argued that a Hagedorn transition occurs nears the horizon for all N>1.
