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…

Four-terminal Josephson junctions: diode effects, anomalous currents and transverse currents
Bijay Kumar Sahoo, Abhiram Soori
We study a multi-terminal Josephson junction consisting of a central spin-orbit-coupled (SOC) region with an in-plane Zeeman field connected to four superconducting terminals. This…

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…
