Holographic Action Principle for -deformation
Amin Faraji Astaneh
We explore the action principle for the holographic -deformation. We develop a scheme in which one can holographically reproduce the action of the Liouville theory deform…
Fermions, boundaries and conformal and chiral anomalies in and dimensions
Amin Faraji Astaneh, Sergey N. Solodukhin
In the presence of boundaries, the quantum anomalies acquire additional boundary terms. In odd dimensions the integrated conformal anomaly, for which the bulk contribution is known…
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.…
