Quantum-metric Bloch oscillations in weakly inhomogeneous electric fields
M. Maneesh Kumar, Md Kaif Faiyaz, Sayan Sarkar +1
Geometric analogs of Bloch oscillations studied so far have relied on Berry curvature. We show that a weakly inhomogeneous electric field adds a distinct quantum-metric term to sem…
Orbital-Splitter Current in Altermagnets
Koushik Ghorai, Sayan Sarkar, Amit Agarwal
In collinear altermagnets, the real-space rotational symmetry of opposite spin sublattices generates a large nonrelativistic spin-splitter current. Orbital transport in this settin…
Electric-Polarization Probe of the Magnon Orbital Moment Current in Altermagnet
Sankar Sarkar, Amit Agarwal
Efficient transport of spin and orbital moments, and their electrical detection, are among the main challenges in spintronics and orbitronics. In magnetic insulators, these current…
Valleytronics in 2D Materials Roadmap
Kyle L. Seyler, Giancarlo Soavi, Bent Weber +30
Valleytronics exploits non-equivalent energy extrema in the electronic band structure of crystalline solids -- the valley degree of freedom -- to encode, manipulate, and read out i…
Extrinsic Spin Splitter Currents in Altermagnets
Sanjay Sarkar, Sayan Sarkar, Amit Agarwal
Altermagnets exhibit momentum-dependent spin splitting despite having zero net magnetization. This enables a spin-splitter effect in which an external electric field generates tran…
