Cosmological Correlations in Power Law Inflation models
Amit Kundu, Prasenjit Paul
Scalar field with non-minimal coupling to curvature scalar is studied in Robertson-Walker background. The infrared limit of two point function, and, in turn, of the energy-momentum…

Calculation of density fluctuation in inflationary epoch
Amit Kundu, S. Mallik, D. Rai Chaudhuri
Starting from an initial state of thermal equilibrium, we derive an expression for the quantum fluctuation in the energy density during the inflationary epoch in terms of the mode…

Baryogenesis and damping in nonminimal electroweak models
A. Kundu, S. Mallik
We study the effect of damping on the generation of baryon asymmetry of the Universe in the standard model of the eletroweak theory with simple extensions of the Higgs sector. The…
