Emergent Universe in f(Q) gravity theories
Hamid Shabani, Avik De, Tee-How Loo
One resolution of the ancient cosmic singularity, i.e., the Big Bang Singularity (BBS), is to assume an inflationary stage preceded by a long enough static state in which the unive…
Scalar perturbation and density contrast evolution in gravity
Ganesh Subramaniam, Avik De, Tee-How Loo +1
The symmetric teleparallel theory offers an alternative gravitational formulation which can elucidate events in the early and late universe without requiring the physical existence…
Complete dark energy scenario in gravity
Raja Solanki, Avik De, P. K. Sahoo
In theoretical physics, the fundamental nature and evolution mechanism of dark energy is still an open question. In General Relativity Theory, the simplest explanation for dark ene…
Isotropization of locally rotationally symmetric Bianchi-I universe in -gravity
Avik De, Sanjay Mandal, J. T. Beh +2
Despite having the somewhat successful description of accelerated cosmology, the early evolution of the universe always challenges mankind. Our promising approach lies in a new cla…
Almost pseudo-Ricci symmetric spacetime solutions in -gravity
Avik De, Loo-Tee How
The objective of the present paper is to study 4-dimensional almost pseudo Ricci symmetric perfect fluid spacetimes . We show that a Robertson-Walker spacetime is $(APRS)…
Energy conditions for a spacetime in -gravity
Avik De, Tee-How Loo, Simran Arora +1
The objective of the present paper is to study 4-dimensional weakly Ricci symmetric spacetimes with non-zero constant Ricci scalar. We prove that such a satisfy…
