Boundary entropy under ambient RG flow in the AdS/BCFT model
arXiv:2004.04929 · doi:10.1103/PhysRevD.101.126004
Abstract
We discuss the change of the boundary entropy under an ambient renormalization group flow. We use conformal perturbation theory to calculate the change of the boundary entropy for -dimensional BCFTs between two nearby fixed points. We also use the AdS/BCFT model to calculate the boundary entropy. We show that the boundary entropy can increase under the ambient RG flow both in conformal perturbation theory and the AdS/BCFT model. In a special case, the change of the boundary entropy in the AdS/BCFT model reduces to that of the conformal perturbation theory.
