Abstract: (arXiv)
The first law for the holographic entanglement entropy of spheres in a boundary CFT with a bulk Lovelock dual is extended to include variations of the bulk Lovelock coupling constants. Such variations in the bulk correspond to perturbations within a family of boundary CFTs. The new contribution to the first law is found to be the product of the variation of the A-type trace anomaly coefficient for even dimensional CFTs, or more generally its extension to include odd dimensional boundaries, times the ratio . Since is a measure of the number of degrees of freedom per unit volume of the boundary CFT, this new term has the form , where the chemical potential is given by the entanglement entropy per degree of freedom.Note:
