Non-linear spin current in the surface states of topological insulators
Srijan Chatterjee, Tarun Kanti Ghosh
Spin Hall effect is one of the primary sources of pure spin current in spintronic devices, observed in spin-orbit coupled materials. In this work, we investigate linear and non-lin…
Non-linear in-plane spin current in spin-orbit coupled 2D hole gases
Srijan Chatterjee, Tarun Kanti Ghosh
The non-linear transport of charge and spin due to the emergence of band geometric effects has garnered much interest in recent years. In this work, we show that a linear in-plane…
Nonlinear magnetotransport in a two-dimensional system with merging Dirac points
Ojasvi Pal, Bashab Dey, Tarun Kanti Ghosh
We study the linear, second-order nonlinear (NL) current and voltage responses of a two-dimensional gapped semi-Dirac system with merging Dirac nodes along the direction under…
Magnus spin Hall and spin Nernst effects in gapped 2D Rashba systems
Priyadarshini Kapri, Bashab Dey, Tarun Kanti Ghosh
We study the Magnus transport in a gapped 2D electron gas with Rashba spin-orbit coupling using semiclassical Boltzmann transport formalism. Apart from its signature in the charge…
Berry curvature induced anisotropic magnetotransport in a quadratic triple-component fermionic system
Ojasvi Pal, Bashab Dey, Tarun Kanti Ghosh
Triple-component fermions are pseudospin-1 quasiparticles hosted by certain three-band semimetals in the vicinity of their band-touching nodes [Phys. Rev. B {\bf 100}, 235201 (2019…
Dynamical polarization, optical conductivity and plasmon mode of a linear triple component fermionic system
Bashab Dey, Tarun Kanti Ghosh
We investigate the density and optical responses of a linear triple component fermionic system in both non-interacting and interacting regimes by computing its dynamical polarizati…
