| Abstract: |
Entanglement is a useful concept in quantum many-body systems introduced from the quantum information theory. In this talk, I will first explain how the entanglement spectrum, the eigenvalue distribution of the reduced density matrix, of CFT changes as a function of the conformal dimensions of scalar operators in it. Then I will introduce a generalization of the entanglement entropy by twisting boundary conditions. Physical meaning of it is to insert charged operators on the entangling surfaces. I will explain a possible gravitational dual of it. |
