Entanglement entropy in higher derivative holography

Understand

We consider holographic entanglement entropy in higher derivative gravity theories.

• Recently Lewkowycz and Maldacena arXiv:1304.4926 have provided a method to derive the equations for the entangling surface from first principles.
• We use this method to compute the entangling surface in four derivative gravity.
• Certain interesting differences compared to the two derivative case are pointed out.
