Spin Currents in Rashba Altermagnets: From Equilibrium to Nonlinear Regimes
Priyadarshini Kapri
We investigate equilibrium (background), linear, and nonlinear spin currents in two-dimensional Rashba spin-orbit coupled altermagnet systems, using a modified spin current operato…
Mechanical properties of 2D metal-organic and covalent-organic frameworks with non trivial topological band dispersion
Priyadarshini Kapri, Takuto Kawakami, Mikito Koshino
Using density functional theory (DFT), we investigate mechanical properties of a few 2D metal-organic frameworks (MOFs) and covalent-organic frameworks (COFs) having Dirac and flat…
Electrical and thermal transport through NIS junction
Mijanur Islam, Priyadarshini Kapri
We investigate the electrical and thermal transport properties of the based normal metal-insulator-superconductor (NIS) junction using Blonder-Tinkham-Klapwijk (BTK) theory…
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…
Role of Berry curvature in the generation of spin currents in Rashba systems
Priyadarshini Kapri, Bashab Dey, Tarun Kanti Ghosh
We study the background (equilibrium), linear and nonlinear spin currents in 2D Rashba spin-orbit coupled systems with Zeeman splitting and in 3D noncentrosymmetric metals using mo…
Topological phase transition induced by band structure modulation in a Chern insulator
Sayan Mondal, Priyadarshini Kapri, Bashab Dey +2
Here we study the systematic evolution of the topological properties of a Chern insulator in presence of an electronic dispersion that can be tuned smoothly from being Dirac-like t…
Valley caloritronics in a photodriven hetero-junction of Dirac materials
Priyadarshini Kapri, Bashab Dey, Tarun Kanti Ghosh
We consider a lateral hetero-junction where the left and right leads are made of monolayer graphene and the middle region is made of a gapped tilted Dirac material (borophene or qu…
Unconventional phases in a Haldane model of dice lattice
Bashab Dey, Priyadarshini Kapri, Ojasvi Pal +1
We propose a Haldane-like model of dice lattice analogous to graphene and explore its topological properties within the tight-binding formalism. The topological phase boundary of t…
Thermopower generation and thermoelectric cooling in a Kane-Mele normal-insulator-superconductor nano-junction
Priyadarshini Kapri, Saurabh Basu
We have studied thermoelectric effect of a Kane-Mele normal-insulator-superconductor (KMNIS) junction at ultra-low temperatures using a modified version of the well-known Blonder-T…
