Superstring entanglement at finite temperature and its Hagedorn behavior

High Energy Physics - Theory 2025-07-09 v2

Abstract

This work demonstrates that a superstring extended density matrix can be defined at finite temperature. This enables the calculation of the extended entanglement entropy between string coordinates. Using a real-time approach, the entanglement entropy is expressed in terms of modular functions, whose proprieties are then used to study Hagedorn behavior.
