- Abstract
- Utilizing the holographic technique, we investigate how the entanglement entropy evolves along the
renormalization group flow. After introducing a new generalized temperature which satisfies the
thermodynamicslike law even in the IR regime, we find that the renormalized entropy and the generalized
temperature in the IR limit approach the thermal entropy and thermodynamic temperature of a real thermal
system. This result implies that the microscopic quantum entanglement entropy in the IR region leads to the
thermodynamic relation up to small quantum corrections caused by the quantum entanglement near the
entangling surface. Intriguingly, this IR feature of the entanglement entropy universally happens regardless
of the detail of the dual field theory and the shape of the entangling surface. We check this IR universality
with a most general geometry called the hyperscaling violation geometry which is dual to a relativistic
nonconformal field theory.
