On holographic entanglement entropy of Horndeski black holes

Understand

We study entanglement entropy in a particular tensor-scalar theory: Horndeski gravity.

• Our goal is two-fold: investigate the Lewkowycz-Maldacena proposal for entanglement entropy in the presence of a tensor-scalar coupling and address a puzzle existing in the literature regarding the thermal entropy of asymptotically AdS Horndeski black holes.
• Using the squashed cone method, i.e.
• turning on a conical singularity in the bulk, we derive the functional for entanglement entropy in Horndeski gravity.
