Spin-resolved ballistic transport in three-terminal Zigzag Graphene Nanoribbon Device
Niharika Tamuli, Saumen Acharjee
We investigate the spin-polarized ballistic transport in a three-terminal Zigzag graphene nanoribbon (ZGNR) device using a tight binding model, non-equilibrium Green function forma…

Field free Josephson diode effect in Ising Superconductor/Altermagnet Josephson junction
Arindam Boruah, Saumen Acharjee, Prasanta Kumar Saikia
Altermagnets (AMs) are an exotic class of antiferromagnet that exhibit spin-splitting even at the absence of net global magnetization and spin-orbit coupling (SOC) effects. In this…
