Flavor corrections to the entanglement entropy

Understand

We consider the holographic entanglement entropy in N=4 SYM coupled to massive flavor degrees of freedom.

• The flavors are introduced by putting D7 branes in AdS_5.
• The resulting geometry including the backreaction of the branes is known in a perturbation expansion in the ratio N_f/N_c.
• We consider the expansion to first order, and compute the entanglement entropy of a region of the boundary.
