چکیده
|
We investigate the one-loop entanglement entropy of two short intervals with small cross ratio x on a complex plane in two-dimensional conformal field theory (cft) using operator product expansion of twist operators. we focus on the one-loop entanglement entropy instead of the general order n rényi entropy, and this makes the calculation much easier. we consider the contributions of stress tensor to order x 10, contributions of w 3 operator to order x 12, and contributions of w 4 operator to order x 14. the cft results agree with the ones in gravity.
