Thermodynamics of a Non-canonical $f (R ˉ, T ˉ)$ gravity

Arijit Panda, Goutam Manna, Saibal Ray +2

This work comprises a study of the thermodynamic behavior of modified $f (R ˉ, T ˉ)$ gravity, which had been developed based on a non-canonical theory known as K-essence theo…

Form Invariance of Raychaudhuri equation in the presence of Inflaton-type fields

Arijit Panda, Debashis Gangopadhyay, Goutam Manna

We show that the Raychaudhuri equation remains form invariant for certain solutions of scalar fields $ϕ$ whose Lagrangian is non-canonical and of the form $\mathcal{L}(X,ϕ)=-V(ϕ)F(…

Null geodesic structure for the Barriola-Vilenkin spacetime via $k$ -essence

Bivash Majumder, Saibal Ray, Goutam Manna

Based on the work of Chandrasekhar [{\it The Mathematical Theory of Black Holes, Oxford Univ. Press (1992)}], we investigate the null geodesic structure of the emergent Barriola-Vi…
