Entanglement Temperature With Gauss-Bonnet Term

High Energy Physics - Theory 2015-07-31 v2

Abstract

We compute the entanglement temperature using the first law-like of thermodynamics, ΔE=TentΔSEE\Delta E=T_{ent} \Delta S_{EE}, up to Gauss-Bonnet term in the Jacobson-Myers entropy functional in any arbitrary spacetime dimension. The computation is done when the entangling region is the geometry of a slab. We also show that such a Gauss-Bonnet term, which becomes a total derivative, when the co-dimension two hypersurface is four dimensional, does not contribute to the finite term in the entanglement entropy. We observe that the Weyl-squared term does not contribute to the entanglement entropy. It is important to note that the calculations are performed when the entangling region is very small and the energy is calculated using the normal Hamiltonian.
