Hypersurface Anchored Variational Principle for General Relativity
Prasanta Sahoo
A hypersurface anchored variational extension of General Relativity is formulated in which the Einstein-Hilbert action is supplemented by a diffeomorphism invariant functional supp…
Global Dynamical Structure of EinsteinScalar Cosmological Systems
Prasanta Sahoo
In this work, a global dynamical analysis of spatially flat FLRW cosmologies driven by a canonical scalar field minimally coupled to gravity is presented. Under suitable regularity…
Stability Protected Phantom Bound in Expansion Modulated Cosmology
Prasanta Sahoo
Recent cosmological observations, including DESI Data Release 2 (DR2) \cite{DESIDR2}, allow for mild redshift evolution of the dark energy equation of state (EoS), motivating renew…
Quintessence scalar field and cosmological constant: Dynamics of a multi-component dark energy model
Prasanta Sahoo, Nandan Roy, Himadri Shekhar Mondal
This study explores the dynamics and phase-space behavior of a multi-component dark energy model, where the dark sector consists of a minimally coupled canonical scalar field and t…
