Electronic confinement of surface states in a topological insulator nanowire
Ruchi Saxena, Eytan Grosfeld, Sebastian E de Graaf +4
We analyze the confinement of electronic surface states in a model of a topological insulator nanowire. Spin-momentum locking in the surface states reduces unwanted backscattering…
Thermoelectric properties of inversion symmetry broken Weyl semimetal-Weyl superconductor hybrid junctions
Ruchi Saxena, Nirnoy Basak, Pritam Chatterjee +2
We theoretically investigate the thermoelectric properties (electronic contribution) of a hybrid structure comprising of an inversion symmetry broken Weyl semimetal (WSM) and intri…
Bulk-edge correspondence and new topological phases in periodically driven spin-orbit coupled materials in the low frequency limit
Ruchi Saxena, Sumathi Rao, Arijit Kundu
We study the topological phase transitions induced in spin-orbit coupled materials with buckling like silicene, germanene, stanene, etc, by circularly polarised light, beyond the h…
Brillouin-Wigner Theory for Floquet Topological Phase Transitions in Spin-orbit Coupled Materials
Priyanka Mohan, Ruchi Saxena, Arijit Kundu +1
We develop the high frequency expansion based on the Brillouin-Wigner (B-W) perturbation theory for driven systems with spin-orbit coupling which is applicable to the cases of sili…
Conductance, Valley and Spin polarization and Tunnelling magneto-resistance in ferromagnetic-normal-ferromagnetic junctions of silicene
Ruchi Saxena, Arijit Saha, Sumathi Rao
We investigate charge conductance and spin and valley polarization along with the tunnelling magneto-resistance (TMR) in silicene junctions composed of normal silicene and ferromag…
