Gradient Ricci Bourguignon solitons on perfect fluid space-times [PDF]
Journal of Mahani Mathematical ResearchThe main purpose of the present paper is about characterizing the properties of the perfect fluid space-time that admits the gradient Ricci-Bourguignon soliton. This gives some results about the stability of the energy-momentum tensor and also under some

Cylindrical wormholes and electromagnetic field
Nuclear Physics B, 2023 In this manuscript, we study the construction of static cylindrically symmetric thin shell wormhole models with an electric charge in the background of f(R,T) gravity.

On a perfect fluid Kahler spacetime
JOURNAL OF ADVANCES IN PHYSICS, 2016 The object of the present paper is to study a perfect fluid K¨ahlerspacetime. A perfect fluid K¨ahler spacetime satisfying the Einstein field equation with a cosmological term has been studied and the existence of killingand conformal killing vectors have been discussed.

ELECTROMAGNETISM AND PERFECT FLUIDS INTERPLAY IN MULTIDIMENSIONAL SPACETIMES [PDF]
The Eleventh Marcel Grossmann Meeting, 2008 We consider fields in (D>2)-dimensional spacetime, whose potential is r-form (skew-symmetric tensor of rank r), the field tensor F being its exterior derivative and the Lagrangian, a function of the quadratic invariant I of this tensor. It is shown that vector field (r=1) describes electromagnetic field only for D=4.

Charged perfect fluid sphere in higher-dimensional spacetime [PDF]
Indian Journal of Physics, 2019 Present paper provides a new model for perfect fluid sphere filled with charge in higher dimensional spacetime admitting conformal symmetry. We consider a linear equation of state with coefficients fixed by the matching conditions at the boundary of the source corresponding to the exterior Reissner-Nordström higher dimensional spacetime.

Journal of High Energy Physics, 2023 In the realm of lower-dimensional accelerating spacetimes, it is well-established that the presence of domain walls, which are co-dimension one topological defects, is a necessary condition for their construction.

Flat holography and Carrollian fluids
Journal of High Energy Physics, 2018 We show that a holographic description of four-dimensional asymptotically locally flat spacetimes is reached smoothly from the zero-cosmological-constant limit of anti-de Sitter holography.

New symmetry for the imperfect fluid
European Physical Journal C: Particles and Fields, 2020 We will address the existence of a new symmetry for an imperfect fluid by introducing local four-velocity gauge-like transformations for the case when there is vorticity.

Stability of generic thin shells in conformally flat spacetimes
European Physical Journal C: Particles and Fields, 2017 Some important spacetimes are conformally flat; examples are the Robertson–Walker cosmological metric, the Einstein–de Sitter spacetime, and the Levi-Civita–Bertotti–Robinson and Mannheim metrics.
