Hagedorn temperature from holography: rotating and charged systems
Francesco Bigazzi, Tommaso Canneti, Federico Castellani +1
Using the string/field theory correspondence as a tool, we study the dependence of the Hagedorn temperature of strongly coupled, planar gauge theories on angular velocities and che…

The divergence of the string partition function due to the exponential growth of states is a well-understood issue in flat spacetime. It can be interpreted as the appearance of tac…
