Entanglement of purification for multipartite states and its holographic dual

open access: yesJournal of High Energy Physics, 2018
We introduce a new information-theoretic measure of multipartite correlations Δ P , by generalizing the entanglement of purification to multipartite states.

Gravitational-magnetic-electric field interaction

open access: yesResults in Physics, 2018
From gravitational redshift/blueshift and the law of conservation of energy, we obtained equations, Δg=fG/μ0B and Δg=fGε0E, for the interaction between gravitational and magnetic/electric field.

Influence of gravitational field on quantum-nondemolition measurement of atomic momentum in the dispersive Jaynes-Cummings model [PDF]

open access: yes, 2006
We present a theoretical scheme based on su(2) algebra to investigate the influence of homogeneous gravitational field on the quantum nondemolition measurement of atomic momentum in dispersive Jaynes-Cummings model.

On Low Hubble Expansion Rate from Planck Data Anomalies

open access: yesGalaxies, 2022
From the linear perturbations of Nash–Greene fluctuations of a background metric, we obtain profiles of Hubble function evolution H(z) and fσ8(z) measurements as compared with the ΛCDM results at intermediate redshifts 0 ...

Gravitational fluctuations of the galaxy distribution [PDF]

open access: yes, 2010
We study the statistical properties of the gravitational field generated by galaxy distribution observed bythe Sloan Digital Sky Survey (DR7). We characterize the probability density function of gravitational force fluctuations and relate its limiting ...

GRAVITATIONAL FIELD OF A ROTATING GRAVITATIONAL DYON [PDF]

open access: yesModern Physics Letters A, 2002
We have obtained the general solution of the Einstein vacuum equation for the axially symmetric stationary metric in which both the Hamilton-Jacobi equation for particle motion and the Klein - Gordon equation are separable. It can be interpreted to describe the gravitational field of a rotating dyon, a particle endowed with both gravoelectric (mass ...

Numerical simulation of gravitational waves from a black hole, using curvature tensors

open access: yesSistemnì Doslìdženâ ta Informacìjnì Tehnologìï, 2020
In this research we formulated the curvature tensors with the system of spherical polar coordinates, which describe the gravitational field and gravitational waves of a black hole; and then we calculated eigenvalues of the curvature tensors to estimate ...

Calculating energy density and spin momentum density of Moon’s gravitational waves in rectilinear coordinates

open access: yesSistemnì Doslìdženâ ta Informacìjnì Tehnologìï, 2019
In this research the energy density was calculated and the spin momentum density of Moon’s gravitational waves in the rectilinear coordinates’ system of Moon’s gravity and Earth’s global temperature. At first, we assumed an action principle that combines
