Entanglement entropy of AdS5 × S5 with massive flavors

We consider backreacted AdS5 × S5 coupled with Nf massive flavors introduced by D7 branes. The backreacted geometry is in the Veneziano limit with fixed Nf/Nc. By dividing one of the directions into a line segment with length l, we get two subspaces. Then we calculate the entanglement entropy between them. With the method of [I. R. Klebanov, D. Kutasov and A. Murugan, Nucl. Phys. B 796, 274 (2008)], we are able to find the cut-off independent part of the entanglement entropy and finally find that this geometry shows no confinement/deconfinement phase transition at zero temperature from the holographic entanglement entropy point of view similar to the case in pure AdS5 × S5.
