Perturbation Dynamics and Structure Formation in Extended Proca-Nuevo Gravity
N. S. Kavya, Avik De, Tee-How Loo
A comprehensive analysis of cosmological perturbations and structure formation is presented for the Extended Proca-Nuevo (EPN) framework, a vector-tensor extension of General Relat…
Universality Classes of Interacting Dark Energy from Spontaneous Symmetry Breaking
Pradosh Keshav MV, NS Kavya, Kenath Arun
Phenomenological models of interacting dark energy (IDE) often treat the late-time activation history of the dark sector coupling as an independent function. We show that in confor…
Traversable Wormhole Solutions in f (Q, Lm) Gravity
K. Suhasini, G. Ravi Kiran, N. S. Kavya +2
We investigate traversable wormhole solutions within the framework of gravity, a symmetric teleparallel theory featuring non-minimal coupling between…
Spontaneous Symmetry Breaking as a Late-Time Trigger for Interacting Dark Energy
Pradosh Keshav MV, NS Kavya, Kenath Arun
Persistent tensions in the Hubble constant (H0) and the matter clustering parameter (S8) motivate late-time new physics that suppresses structure growth without significantly alter…
The Study on Modified Theories of General Relativity: A Differential Geometric Approach
N. S. Kavya
The introduction of General Relativity (GR) in 1915 revolutionized our understanding of gravity, but over time, its limitations in explaining phenomena like dark energy, dark matte…
