Title: Mutual informations in 1+1 dimensional CFT's (quantum critical chains)

Abstract: I will first introduce Shannon entropy and its generalization Renyi entropy for quantum chains. Despite the base dependence of these quantities I will show that one can extract the central charge of the critical chains by introducing the quantities; mutual Shannon entropy and mutual Renyi entropy. I will emphasize on the important role of especial bases, we call them conformal basis, in extracting the central charge of the system.
