Graphene: Junctions and STM Spectra
M. Maiti, K. Saha, K. Sengupta
In this review we focus on the effect of the Dirac nature of graphene quasiparticles on two separate aspects. The first of these involves transport across superconducting graphene…
Quantum phase transition of ultracold bosons in the presence of a non-Abelian synthetic gauge field
T. Grass, K. Saha, K. Sengupta +1
We study the Mott phases and the superfluid-insulator transition of two-component ultracold bosons on a square optical lattice in the presence of a non-Abelian synthetic gauge fiel…
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…
Spin polarized STM spectra of Dirac Fermions on the surface of a topological insulator
K. Saha, Sourin Das, K. Sengupta +1
We provide a theory for the tunneling conductance of Dirac Fermions on the surface of a topological insulator as measured by a spin-polarized scanning tunneling microscope t…
