• Abstract: Using extended island formula we compute entanglement entropy of Hawking radiation for black hole solutions of certain gravitational models containing higher derivative terms. To be concrete we consider two different four dimensional models to compute entropy for both asymptotically flat and AdS black holes. One observes that the resultant entropy follows the Page curve, thanks to the contribution of the island, despite the fact that the corresponding gravitational models might be non-unitary.

  We numerically explore the interplay of fractal geometry and quantum entanglement by analyzing entanglement entropy and the entanglement contour in the scaling limit. For gapless ground states exhibiting a finite density of states at the chemical potential, we reveal a super-area law. A novel self-similar and universal pattern termed an entanglement fractal'' in the entanglement contour data as we approach the scaling limit bears resemblance to intricate Chinese paper-cutting designs.

• Black Hole from Entropy Maximization [0.0]
  One quantum characterization of a black hole motivated by (local) holography and thermodynamics is that it maximizes thermodynamic entropy for a given surface area. We explore this possibility by solving the 4D semi-classical Einstein equation with many matter fields, and find a picture of a black hole. For spherical static highly-excited configurations, we apply local typicality and estimate the entropy including self-gravity to derive its upper bound.

  We show that the Page curve can still be realized even if information is lost and the information paradox can be attributed to the measurement problem. Though speculative, the similarities between the black hole information problem and the measurement problem may suggest some link in the origins of the two fundamental issues of distant fields.

A formula calculating the capacity is derived using the gravitational path integral, from which we speculate that the capacity has a discontinuity at the Page time. We show that the capacity of entanglement is saturated by the thermal capacity of the black hole in the high temperature limit.
