"Universal aspects of Entanglement entropy in Interface CFT"

Abstract: The divergence of entanglement entropy in QFT has been long studied. In particular in 2D the coefficient of the universal logarithm divergence encodes the central charge of the CFT. In this talk we study from holography and field theory side what are these coefficients for entanglement entropy in (1+1)D interface CFT, and their relations. We will also generalize it to higher dimensional ICFT on a sphere.
