Giant Spin Magnetization from Quantum Geometry in Altermagnets
Neelanjan Chakraborti, Sudeep Kumar Ghosh, Snehasish Nandy
Altermagnets host spin-split band structures while exhibiting vanishing equilibrium spin magnetization, making field-induced responses a direct probe of their quantum geometry. A c…
Josephson diode effect in multichannel Rashba nanowires: Role of inter-subband coupling
Ardamon Sten, Sudeep Kumar Ghosh
The Josephson diode effect (JDE) has attracted significant attention for enabling directional, dissipationless supercurrents, positioning Josephson junctions as promising building…
Probing persistent spin textures through nonlinear magnetotransport
Neelanjan Chakraborti, Akash Dey, Snehasish Nandy +2
Persistent spin textures (PST) are special spin configurations in spin-orbit-coupled systems in which the spin polarization acquires a symmetry-enforced momentum-independent orient…
Intrinsic Nonlinear Gyrotropic Magnetic Effect Governed by Spin-Rotation Quantum Geometry
Neelanjan Chakraborti, Snehasish Nandy, Sudeep Kumar Ghosh
Nonlinear magnetic response driven by time-periodic magnetic fields offers a distinct route to probe spin-resolved quantum geometry beyond conventional electric-field-driven nonlin…
Gyrotropic Fingerprints of Magnetic Topological Insulator-Unconventional Magnet Interfaces
Neelanjan Chakraborti, Snehasish Nandy, Sudeep Kumar Ghosh
Unambiguously identifying unconventional magnetic orders requires probes directly sensitive to their momentum-dependent spin-split band structures. Here, we employ a Zeeman quantum…
Zeeman Quantum Geometry as a Probe of Unconventional Magnetism
Neelanjan Chakraborti, Sudeep Kumar Ghosh, Snehasish Nandy
Unconventional magnets with momentum-dependent spin-splitting but zero net magnetization form a recently identified class of collinear magnets that are challenging to probe via con…
