In this paper, we use the holographic method to compute the entanglement entropy for different regions in the fourth-order scale-invariant theory of gravity. In four dimensions, the action of scale-invariant gravity contains a parameter where the moduli space has some distinguished points, precisely, the space of solutions contains the Log-gravity and for this specific solution, […]
In this paper, using complexity equals action proposal, we investigate holographic complexity for hyperscaling violating theories on different subregions of space-time enclosed by the null boundaries. By recalling the computation of on-shell action for certain subregions of the intersection between the Wheeler DeWitt patch, as well as, the future interior of a two-sided black brane, […]
AbstractIn this paper, we study some non-local measurements of quantum correlations in extended gravities with higher-order curvature terms, including conformal gravity. Precisely, we consider higher-curvature correction on holographic mutual information in conformal gravity. There is in fact one deformation in the states because of the higher-curvature corrections. Here by making use of the holographic methods, […]
AbstractIn this work, under a small perturbation of the background metric with the squeezing of other fields (scalar field in our case), the linear form of the energy-momentum tensor is calculated in terms of the perturbation factor. The linear form of the Klein-Gordon equation for a scalar field with both minimally and conformally coupled cases […]
In this paper, a set of two-fluids equations based on the quantum magnetic hydrodynamic model (QMHD) for electron-positron plasma were considered and the role of spin in different spin-spin, and spin-field interactions were briefly discussed. Furthermore, effects of density and heterogeneity in the equations were considered. For each of the two electron and positron fluids, […]
