Entanglement entropy and Fisher information metric for closed bosonic strings in homogeneous plane wave background
H. Dimov, S. Mladenov, R. C. Rashkov +1
We derive the extended renormalized entanglement entropy (EREE) and the Fisher information metric in the case of closed bosonic strings in homogeneous plane wave background. Our in…
Entanglement of higher-derivative oscillators in holographic systems
Hristo Dimov, Stefan Mladenov, Radoslav C. Rashkov +1
We study the quantum entanglement of coupled Pais-Uhlenbeck oscillators using the formalism of thermo-field dynamics. The entanglement entropy is computed for the specific cases of…
Non-abelian T-duality of Pilch-Warner background
Hristo Dimov, Stefan Mladenov, Radoslav C. Rashkov +1
In this work we obtain the non-abelian T-dual geometry of the well-known Pilch-Warner supergravity solution in its infrared point. We derive the dual metric and the NS two-form by…
Large J expansion in ABJM theory revisited
H. Dimov, S. Mladenov, R. C. Rashkov
Recently there has been progress in the computation of the anomalous dimensions of gauge theory operators at strong coupling by making use of AdS/CFT correspondence. On string theo…
