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…
Sensitivity of the JEM-EUSO telescope to gravity effects in neutrino-induced air showers
Stefan Mladenov, Galina Vankova, Roumen Tsenov +2
We examine the JEM-EUSO sensitivity to gravity effects in the context of Randall-Sundrum (RS) model with a single extra dimension and small curvature of the metric. Exchanges of re…
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…
Detection of Earth-skimming UHE tau neutrino with the JEM-EUSO detector
Galina Vankova, Stefan Mladenov, Marian Bogomilov +3
The ultra high energy cosmic neutrinos are powerful astrophysical probes for both astrophysical mechanisms of particle acceleration and fundamental interactions. They open a window…
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…
Heating of the solar corona by Alfven waves - self-induced opacity
Todor M. Mishonov, Nedeltcho I. Zahariev, Rositsa V. Topchiyska +3
Static distributions of temperature and wind velocity at the transition region are calculated within the framework of magnetohydrodynamics (MHD) of completely ionized hydrogen plas…
