Entropy discrepancy and total derivatives in trace anomaly
Amin Faraji Astaneh, Alexander Patrushev, Sergey N. Solodukhin
In this note we address the discrepancy found by Hung, Myers and Smolkin between the holographic calculation of entanglement entropy (using the Jacobson-Myers functional for the ho…
Entropy vs Gravitational Action: Do Total Derivatives Matter?
Amin Faraji Astaneh, Alexander Patrushev, Sergey N. Solodukhin
The total derivatives in the gravitational action are usually disregarded as non-producing any non-trivial dynamics. In the context of the gravitational entropy, within Wald's appr…
What surface maximizes entanglement entropy?
Amin Faraji Astaneh, Gary Gibbons, Sergey N. Solodukhin
For a given quantum field theory, provided the area of the entangling surface is fixed, what surface maximizes entanglement entropy? We analyze the answer to this question in four…
Quantum Local Quench, AdS/BCFT and Yo-Yo String
Amin Faraji Astaneh, Amir Esmaeil Mosaffa
We propose a holographic model for local quench in 1+1 dimensional Conformal Field Theory (CFT). The local quench is produced by joining two identical CFT's on semi-infinite lines.…
