Geometric Photon-drag Effect in Unconventional Magnets
Bristi Ghosh, Vivek Pandey, Malay Bandyopadhyay +2
The photon-drag effect is a nonlinear optical phenomenon in which the finite momentum carried by incident photons is transferred to charge carriers, thereby generating a dc photocu…

Quantum geometry-driven photogalvanic responses in semi-Dirac systems
Bristi Ghosh, Malay Bandyopadhyay, Snehasish Nandy
The photogalvanic effect (PGE), a fundamental nonlinear optical phenomenon in non-centrosymmetric materials, generates direct photocurrent under polarized light. Using quantum kine…
