Periodic dynamics of fermionic superfluids in the BCS regime
Analabha Roy, Raka Dasgupta, Sanhita Modak +2
We study the zero temperature non-equilibrium dynamics of a fermionic superfluid in the BCS limit and in the presence of a drive leading to a time dependent chemical potential $μ(t…
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…
Fermionic Chern-Simons Theory of SU(4) Fractional Quantum Hall Effect
Sanhita Modak, Sudhansu S. Mandal, K. Sengupta
We develop a Fermionic Chern-Simons (CS) theory for the fractional quantum Hall effect in monolayer graphene with SU(4) symmetry, arising from the spin and the valley degrees of fr…
