Rényi entropy and conformal defects

  title={R{\'e}nyi entropy and conformal defects},
  author={Lorenzo Bianchi and Marco Meineri and Robert C. Myers and Michael Smolkin},
We propose a field theoretic framework for calculating the dependence of Rényi entropies on the shape of the entangling surface in a conformal field theory. Our approach rests on regarding the corresponding twist operator as a conformal defect and in particular, we define the displacement operator which implements small local deformations of the entangling surface. We conjecture a simple relation between the coefficient defining the two-point function of the displacement operator and the… CONTINUE READING
