Tuning the conductance of Dirac fermions on the surface of a topological insulator
S. Mondal, D. Sen, K. Sengupta +1
We study the transport properties of the Dirac fermions with Fermi velocity on the surface of a topological insulator across a ferromagnetic strip providing an exchange field…

Bose-Hubbard model on a star lattice
Sergei V. Isakov, K. Sengupta, Yong Baek Kim
We analyze the Bose-Hubbard model of hardcore bosons with nearest neighbor hopping and repulsive interactions on a star lattice using both quantum Monte Carlo simulation and dual v…

Unconventional scanning tunneling conductance spectra for graphene
K. Saha, I. Paul, K. Sengupta
We compute the tunneling conductance of graphene as measured by a scanning tunneling microscope (STM) with a normal/superconducting tip. We demonstrate that for undoped graphene wi…
