Thawing quintessence from the inflationary epoch to today
Gaveshna Gupta, Raghavan Rangarajan, Anjan A. Sen
Using the latest observational data we obtain a lower bound on the initial value of the quintessence field in thawing quintessence models of dark energy. For potentials of the form…
A Geometric Approach to Modulus Stabilization
Sampurn Anand, Debajyoti Choudhury, Anjan A. Sen +1
Modulus stabilization, a must for explaining the hierarchy problem in the context of the Randall-Sundrum (RS) scenario, is traditionally achieved through the introduction of an ext…
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;…
