Finite-temperature topological entanglement entropy for fractons

ORAL

Abstract

We consider the finite-temperature topological entanglement entropy (TEE) for topological-ordered systems. We found, quite generally, that the finite-temperature TEE is a piece-wise constant function for CSS codes, which include the toric code and some fracton models like Haah's code and the X-cube model. We also discuss the phase transition structure of CSS codes and possible connections with self-correctness.
