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…
Engineering Giant Thermoelectric Performance through Electrode-Coupling Geometry and Magnetic Flux in Quasiperiodic Su-Schrieffer-Heeger Rings
Sridhar, Souvik Roy, Malay Bandyopadhyay
We investigate coherent thermoelectric transport in magnetic-flux-threaded quasiperiodic Su-Schrieffer-Heeger (SSH) rings with engineered multi-site electrode couplings using the n…
Interplay of Electrode Coupling Engineering, Quasiperiodicity, and Magnetic Flux in Quantum Transport through a Su-Schrieffer-Heeger Ring
Sridhar, Souvik Roy, Malay Bandyopadhyay
We reveal that engineering electrode-coupling configurations can fundamentally reshape coherent transport phenomena in quasiperiodic quantum systems. Leveraging nonequilibrium Gree…
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…
