11:00 - 12:00 Theory Weekly Seminar(TWS)H0 tension as a hint for new physics School PARTICLES AND ACCELERATORS Abstract: In the vacuum state of a CFT, the entanglement entropy of singular surfaces contains a logarithmic universal term which is only due to the singularity of the entangling surface. 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 ... |
