Faulkner, Lewkowycz and Maldacena (FLM) proposed the first order quantum correction to Ryu-Takanayagi conjecture on the holographic entanglement entropy.
We will describe how to calculate this correction for various excited states of free scalar theory in AdS3. This involves computation of perturbed minimal area and bulk entanglement entropy. We note a scaling property in both of these quantities and hence in the semiclassi-cal holographic entanglement entropy of the descendants w.r.t the primary excitation in the small interval limit. Using this property one can find per-fect agreement between the holographic entanglement entropy of bulk and boundary theory upto subleading order. This can be extended for the superposed states also, including states which are time-dependent and break angular symmetry.
