Superfluid-Insulator transition of two-species bosons with spin-orbit coupling
Saptarshi Mandal, Kush Saha, K. Sengupta
Motivated by recent experiments [Y.J. Lin {\it et al.}, Nature {\bf 471}, 83 (2011)], we study Mott phases and superfluid-insulator (SI) transitions of two-species ultracold bosoni…

Dynamic freezing of strongly correlated ultracold bosons
S. Mondal, D. Pekker, K. Sengupta
We study the non-equilibrium dynamics of ultracold bosons in an optical lattice with a time dependent hopping amplitude J(t)=J_0 +δJ \cos(ωt) which takes the system from a superflu…

Spin injection into a metal from a topological insulator
S. Modak, K. Sengupta, Diptiman Sen
We study a junction of a topological insulator with a thin two-dimensional (2D) non-magnetic or partially polarized ferromagnetic metallic film deposited on a 3D insulator. We show…
