Holographic Entanglement Entropy in Lovelock Gravities

Understand

We study entanglement entropies of simply connected surfaces in field theories dual to Lovelock gravities.

• We consider Gauss-Bonnet and cubic Lovelock gravities in detail.
• In the conformal case the logarithmic terms in the entanglement entropy are governed by the conformal anomalies of the CFT; we verify that the holographic calculations are consistent with this property.
• We also compute the holographic entanglement entropy of a slab in the Gauss-Bonnet examples dual to relativistic and non-relativistic CFTs and discuss its properties.
