Thermodynamics and holographic entanglement entropy for spherical black holes in 5D Gauss-Bonnet gravity

摘要: The holographic entanglement entropy is studied numerically in (4+1)-dimensional spherically symmetric Gauss-Bonnet AdS black hole spacetime with compact boundary. On the bulk side undergoes a van der Waals-like phase transition extended space, which reviewed emphasis on behavior temperature-entropy plane. boundary, we calculated regularized HEE of disk region different sizes. We find strong numerical evidence for failure equal area law isobaric curves temperature-HEE plane and correctness first entropy, briefly give an explanation why latter may serve as reason former, i.e.
