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 Optical Responses in 1T-MX Monolayers: A Symmetry-Constrained Slater-Koster Tight-Binding Approach
Bikram Baruah, Snehasish Nandy, Subhasis Panda
Centrosymmetric 1T-MX monolayers(MLs) have attracted considerable attention owing to their intriguing transport properties and potential technological applications arising from…
Spin-phonon interaction in a symmetry-enforced spin-polarized state
Suman Kalyan Pradhan, Dayal Das, Shubham Patel +8
Symmetry-governed magnetic materials have emerged as a promising platform for spintronic functionalities without net magnetization or stray magnetic fields, motivating the explorat…
Giant Spin Magnetization from Quantum Geometry in Altermagnets
Neelanjan Chakraborti, Sudeep Kumar Ghosh, Snehasish Nandy
Altermagnets host spin-split band structures while exhibiting vanishing equilibrium spin magnetization, making field-induced responses a direct probe of their quantum geometry. A c…
Semiclassical theory of frequency dependent linear magneto-optical transport in Weyl semimetals
Azaz Ahmad, Pankaj Bhalla, Snehasish Nandy +1
We develop a semiclassical Boltzmann theory for frequency-dependent magneto-optical transport in Weyl semimetals (WSMs), incorporating momentum-dependent relaxation via a scatterin…
Magnetic field Controlled Anderson Delocalization in a Spinful Non-Hermitian Chain
Moirangthem Sanahal, Subhasis Panda, Snehasish Nandy
Anderson localization (AL) and the non-Hermitian skin effect (NHSE) represent two paradigmatic localization phenomena driven, respectively, by disorder and non-Hermiticity. In one-…
Probing persistent spin textures through nonlinear magnetotransport
Neelanjan Chakraborti, Akash Dey, Snehasish Nandy +2
Persistent spin textures (PST) are special spin configurations in spin-orbit-coupled systems in which the spin polarization acquires a symmetry-enforced momentum-independent orient…
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…
Intrinsic Nonlinear Gyrotropic Magnetic Effect Governed by Spin-Rotation Quantum Geometry
Neelanjan Chakraborti, Snehasish Nandy, Sudeep Kumar Ghosh
Nonlinear magnetic response driven by time-periodic magnetic fields offers a distinct route to probe spin-resolved quantum geometry beyond conventional electric-field-driven nonlin…
