We consider the relevant perturbation of a three-dimensional CFT for the singular entangling surface. We observe that in addition to the universal term due to the entangling surface, there is a new logarithmic term which corresponds to a relevant perturbation of the conformal field theory with a coefficient depending on the scaling dimension of the relevant operator. We also find a new power-law divergence in the holographic entanglement entropy. In addition ... |
