One-dimensional spin-orbit coupled Dirac system with extended -wave superconductivity: Majorana modes and Josephson effects
Adithi Udupa, Abhishek Banerjee, K. Sengupta +1
Motivated by the spin-momentum locking of electrons at the boundaries of topological insulators, we study a one-dimensional system of spin-orbit coupled massless Dirac electrons wi…

Transport on a topological insulator surface with a time-dependent magnetic barrier
Adithi Udupa, K. Sengupta, Diptiman Sen
We study transport across a time-dependent magnetic barrier present on the surface of a three-dimensional topological insulator. We show that such a barrier can be implemented for…

Transport in a thin topological insulator with potential and magnetic barriers
Adithi Udupa, K. Sengupta, Diptiman Sen
We study transport across either a potential or a magnetic barrier which is placed on the top surface of a three-dimensional thin topological insulator (TI). For such thin TIs, the…
