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…
