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 Third-Harmonic Generation
Sanjay Sarkar, Debottam Mandal, Amit Agarwal
Third-harmonic generation (THG) is a key nonlinear optical process for ultrafast imaging, terahertz (THz) signal generation, and symmetry-sensitive probes, often dominating in cent…

Third-order rectification in centrosymmetric metals
Sanjay Sarkar, Amit Agarwal
Rectification, the conversion of AC fields into DC currents, is crucial for optoelectronic applications such as energy harvesting and wireless communication. However, it is convent…
