Intranight optical variability of γ-ray loud Narrow Line Seyfert 1 galaxies
Vaidehi S. Paliya, C. S. Stalin, Brijesh Kumar +4
The Large Area Telescope (LAT) onboard the {\it Fermi} Gamma Ray Space Telescope has detected γ-ray emission from some Narrow Line Seyfert 1(NLSy1) galaxies. This indicates the pre…
FRW type of cosmology with a Chaplygin gas
D. Panigrahi, S. Chatterjee
The evolution of a universe modelled as a mixture of generalised Chaplygin gas and ordinary matter field is studied for a Robertson Walker type of spacetime. This model could inter…
Mean field analysis of quantum phase transitions in a periodic optical superlattice
Arya Dhar, Manpreet Singh, Ramesh V. Pai +1
In this paper we analyze the various phases exhibited by a system of ultracold bosons in a periodic optical superlattice using the mean field decoupling approximation. We investiga…
Three body on-site interactions in ultracold bosonic atoms in optical lattices and superlattices
Manpreet Singh, Arya Dhar, Tapan Mishra +2
The Mott insulator-superfluid transition for ultracold bosonic atoms in an optical lattice has been extensively studied in the framework of the Bose-Hubbard model with two-body on-…
