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…

Band geometric transverse current driven by inhomogeneous AC electric field
M. Maneesh Kumar, Sanjay Sarkar, Amit Agarwal
We develop a semiclassical theory for electron wavepacket dynamics in the presence of an inhomogeneous AC electric field. While static electric-field gradients are known to generat…

Band geometry induced electro-optic effect and polarization rotation
M. Maneesh Kumar, Sanjay Sarkar, Amit Agarwal
Electric field-induced modulation of the optical properties is crucial for amplitude and phase modulators used in photonic devices. Here, we present a comprehensive study of the ba…
