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.
