Light Induced Quantum Anomalous Hall Effect in Cubic Rashba Spin-Orbit Coupled Systems
Debabrata Sinha
We investigate topological phase transitions in a two-dimensional electron system with cubic Rashba spin-orbit coupling driven by circularly polarized light. Within the Floquet fra…
Giant nonlinear response due to unconventional oscillation in Nodal-line semimetals
Debabrata Sinha, A. Taraphder
Quantum oscillations in magnetoconductance of a material at low temperatures and in presence of an intense magnetic field are described by the Shubnikov de Haas (SdH) effect. It is…
Josephson effect in type-I Weyl Semimetals
Debabrata Sinha
The emergent Weyl fermions in condensed matter generally break the Lorentz invariance resulting in a tilted (type-I) or over-tilted (type-II) energy dispersion. The tilting energy…
Chirality-dependent planar Hall effect in inhomogeneous Weyl semimetals
Suvendu Ghosh, Debabrata Sinha, Snehasish Nandy +1
The planar Hall effect (PHE), the appearance of an in-plane transverse voltage in the presence of co-planar electric () and magnetic () fields, occurs in re…
Josephson junctions of Weyl and multi-Weyl semimetals
Kirill Kulikov, Debabrata Sinha, Yu. M. Shukrinov +1
We study a Josephson junction involving a Weyl and a multi-Weyl semimetal separated by a barrier region of width created by putting a gate voltage over the Weyl semimetal…
Transport across junctions of a Weyl and a multi-Weyl semimetal
Debabrata Sinha, K. Sengupta
We study transport across junctions of a Weyl and a multi-Weyl semimetal (WSM and a MSM) separated by a region of thickness which has a barrier potential . We show that in…
{\em Zitterbewegung} in Spin-Orbit Coupled Systems and Ehrenfest's Theorem
Debabrata Sinha, Jayanta K. Bhattacharjee
We use Ehrenfest's theorem to provide a particularly simple derivation of the {\em zitterbewegung} in the dynamics of initial Gaussian wave packets in a two-dimensional electron ga…
Spin Transport and Spin Pump in Graphene-like Materials: Effect of tilt in Dirac cones
Debabrata Sinha
We study the spin transport phenomena in two-dimensional graphene-like materials with arbitrary tilted Dirac cones. The tilt arises due to next-nearest hopping when the bottom of t…
Andreev tunnelling and Josephson current in light irradiated graphene
Debabrata Sinha, Satyaki Kar
We investigate the Andreev tunneling and Josephson current in graphene irradiated with high-frequency linearly polarized light. The corresponding stroboscopic dynamics can be solve…
Spin texture of an irradiated warped topological insulator surface
Debabrata Sinha
Topological insulator is a new state of matter which exhibits exotic surface electronic properties. Determining the spin texture of this class of material is of paramount importanc…
Bound state and persistent currents in the presence of torsion and Rashba spin-orbit coupling
Debabrata Sinha
We study a model of an electron on a cylindrical surface, which is coupled to the torsion field due to a dislocation along the axis of the cylinder. We discuss the effect of this t…
