Query: Extremal Surfaces And Entanglement Entropy   We have obtained the equation of the extremal hypersurface by considering the
Jacobson-Myers functional and computed the entanglement entropy. In this
context, we show that the higher derivative corrected extremal surfaces can not
penetrate the horizon. Also, we have studied the entanglement temperature and
entanglement entropy for low excited states for such higher derivative theories
when the entangling region is of the strip type.
