Cosmic Acceleration from a Simultaneous Variation of Fundamental Constants
Malavika K, Soumya Chakrabarti
We discuss the possibility of a simultaneous cosmic variation of two fundamental entities: the Newtonian gravitational coupling and the electron mass . We show that this v…

Acceleration from a Phase of Entropic Balance
Soumya Chakrabarti
We discuss the notion of generating a cosmic inflation without any big bang singularity. It has been proved recently by Good and Linder (arXiv : 2503.02380v1) that such an expansio…

A Cosmological Reconstruction of the Higgs Vacuum Expectation Value
Soumya Chakrabarti, Anagha V, Selva Ganesh +1
We present a simple toy model of cosmic acceleration driven purely by a self-interacting scalar field embedded in theory of grand unification. The scalar self-interaction is Higgs-…
