Interface controlled spin filtering and nonreciprocal transport in Altermagnet/Ising superconductor junctions
Arindam Boruah, Saumen Acharjee, Prasanta Kumar Saikia
We investigate theoretically spin-resolved transport, spin filtering, and nonreciprocal effects in an Altermagnet/Ising superconductor (AM/ISC) junction with a spin-active interfac…
Nonlinear magnetoelastic wave dynamics and field tunable soliton excitations in hexagonal multiferroic media
Saumen Acharjee, Kallol Kavas Hazarika, Rajneesh Kakoti
We investigate nonlinear magnetoelastic wave dynamics and electrically tunable soliton excitations in hexagonal multiferroic media. By varying the magnetoelastic coupling strength…
Unconventional spin valve effect in altermagnets induced by Rashba spin orbit coupling and triplet superconductivity
Saumen Acharjee, Aklanta Dihingia, Nayanav Sonowal +1
We theoretically investigate spin dependent transport in altermagnet/triplet superconductor/altermagnet (AM/TSC/AM) junctions in the presence of interfacial Rashba spin orbit coupl…
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…
Quantum Capacitance and Electronic Properties of a Hexagonal Boron Nitride based FET Gas Sensor
Saumen Acharjee
We present a comprehensive theoretical investigation of gas sensing in monolayer hexagonal boron nitride (h-BN) based field-effect transistors (FET) using the non-equilibrium Green…
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…
