Field-free transverse response in altermagnet and topological insulator heterojunctions
Bijay Kumar Sahoo, Abhiram Soori
We theoretically investigate the transport properties of a topological insulator (TI) connected to two-dimensional altermagnetic (AM) leads in the absence of an external magnetic f…

Giant field-free transverse Josephson diode effect in altermagnets
Bijay Kumar Sahoo, Abhiram Soori
We predict a field-free transverse Josephson diode effect in altermagnets (AMs) with Rashba spin--orbit coupling, achieving diode efficiencies exceeding and unidirectional…

Persistent currents in mesoscopic spin-orbit coupled rings due to an applied Zeeman field
Bijay Kumar Sahoo, Subroto Mukerjee, Abhiram Soori
Persistent currents (PCs) in mesoscopic rings have been a subject of intense investigation since their proposal by Büttiker, Landauer, and Imry in 1983. In this paper, we explore t…
