Structural and electronic properties of the Nb-cluster compound GaNbX (X = S, Se)
Asad Niazi, A. K. Rastogi
We report resistivity, thermopower and magnetic susceptibility measurements on the Nb-cluster compounds GaNbX (X = S, Se), derived from vacancy ordered spine…
Pseudo-forces in quantum mechanics
Pravabati Chingangbam, Pankaj Sharan
Dynamical evolution is described as a parallel section on an infinite dimensional Hilbert bundle over the base manifold of all frames of reference. The parallel section is defined…
Inflation With Oscillations
M. Sami
In this paper we investigate the general features of "Oscillatory Inflation". In adiabatic approximation, we derive a general formula for the number of e-foldings which…
Relic Gravity Waves from Braneworld Inflation
Varun Sahni, M. Sami, Tarun Souradeep
We discuss a scenario in which extra dimensional effects allow a scalar field with a steep potential to play the dual role of the inflaton as well as dark energy (quintessence). Th…
Exact Inflationary Solution On The Brane
M. Sami
We study the evolution of universe with a single scalar field of constant potential minimally coupled to gravity in the brane world cosmology.We find an exact inflationary solution…
