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…

Renormalization group approach to spinor Bose-Fermi mixtures in a shallow optical lattice
S. Modak, S. -W. Tsai, K. Sengupta
We study a mixture of ultracold spin-half fermionic and spin-one bosonic atoms in a shallow optical lattice where the bosons are coupled to the fermions via both density-density an…
