Query: Generalized gravitational entropy of probe branes: flavor entanglement
  holographically   The notion of generalized gravitational entropy introduced by Lewkowycz and
Maldacena allows, via the AdS/CFT correspondence, to calculate CFT entanglement
entropies. We adapt the method to the case where flavor branes are present and
treated in the probe approximation. This allows to calculate the leading flavor
correction to the CFT entanglement entropy from the on-shell action of the
probe, while dealing with the backreaction is avoided entirely and from the
outset. As an application we give concise derivations for the contribution of
massless and massive flavor degrees of freedom to the entanglement entropy in
N=4 SYM theory.
