Cosmological evolution in a two-brane warped geometry model
Sumit Kumar, Anjan A. Sen, Soumitra SenGupta
We study an effective 4-dimensional scalar-tensor field theory, originated from an underlying brane-bulk warped geometry, to explore the scenario of inflation. It is shown that the…

Clustering GCG: a viable option for unified dark matter-dark energy?
Sumit Kumar, Anjan A. Sen
We study the clustering Generalized Chaplygin Gas (GCG) as a possible candidate for dark matter-dark energy unification. The vanishing speed of sound () for the GCG fl…

Inflationary generalized Chaplygin gas and dark energy in the light of the Planck and BICEP2 experiments
Bikash R Dinda, Sumit Kumar, Anjan A. Sen
In this work, we study an inflationary scenario in the presence of Generalized Chaplygin Gas (GCG). We show that in Einstein gravity, GCG is not a suitable candidate for inflation;…
