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…
