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…
Magnetic field Controlled Anderson Delocalization in a Spinful Non-Hermitian Chain
Moirangthem Sanahal, Subhasis Panda, Snehasish Nandy
The paper studies how an external magnetic field can induce Anderson delocalization in a one‑dimensional spinful non‑Hermitian chain by modifying the competition between disorder‑d…
Unveiling Novel Resonant Interband Contribution to Polarizability in three-dimensional systems
Vivek Pandey, Snehasish Nandy, Pankaj Bhalla
Polarizability plays an essential role in characterizing key phenomena, such as the screening effects, collective excitations, and dielectric functions present in the system. In th…
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…
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…
