Néel vector controlled charge and spin transport in altermagnetic junctions
Shubham Ghadigaonkar, Sachchidanand Das, Abhiram Soori
Altermagnets (AMs) - magnetic materials that have spin-split bandstructure with zero net spin polarization can be classified as weak or strong depending upon the strength of alterm…
Orientation dependent anomalous Hall and spin Hall currents at junctions of altermagnets with -wave magnets
Sachchidanand Das, Abhiram Soori
We study charge and spin transport across a junction between an altermagnet (AM) and a -wave magnet (PM) using a continuum model with boundary conditions tailored to the spin-sp…
All-electrical scheme for valley polarization in graphene
Sachchidanand Das, Abhiram Soori
We propose an all-electrical setup to generate valley polarization in graphene. A finite graphene sheet is connected to two normal metal electrodes each with two terminals along it…
Crossed Andreev reflection in altermagnets
Sachchidanand Das, Abhiram Soori
Crossed Andreev reflection (CAR) is a scattering phenomenon occurring in a superconductor (SC) connected to two metallic leads, where an incident electron on one side of the SC eme…
