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…
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…
Cosmic expansion beyond CDM: Investigating power-law and logarithmic corrections
M. Koussour, N. S. Kavya, V. Venkatesha +1
The cosmic acceleration observed in the expansion of the Universe has sparked extensive research into the nature of dark energy, which is known to constitute approximately 70\% of…
Governing accelerating Universe via newly reconstructed Hubble parameter by employing empirical data simulations
L. Sudharani, Kazuharu Bamba, N. S. Kavya +1
A new parametrization of the Hubble parameter is proposed to explore the issue of the cosmological landscape. The constraints on model parameters are derived through the Markov Cha…
