Holographic entanglement entropy in insulator/superconductor transition with Born-Infeld electrodynamics

arXiv:1401.6505 · doi:10.1007/JHEP05(2014)058

Abstract

We investigate the holographic entanglement entropy in the insulator/superconductor phase transition for the Born-Infeld electrodynamics with full backreaction in five-dimensional AdS soliton spacetime. We note that the holographic entanglement entropy is a good probe to study the properties of the phase transition, and the Born-Infeld factor has no effect on the critical chemical potential . We find that both in the half space and the belt one, the non-monotonic behavior of the entanglement entropy versus the chemical potential is a general property, and the entanglement entropy increases with the increase of the Born-Infeld factor in the superconductor phase. Particularly, there exists confinement/deconfinement phase transition in the strip geometry and the critical width is dependent of the Born-Infeld parameter.
