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…

Non-trivial phonon dynamics and significant electron-phonon coupling of the high frequency modes in a Dirac semimetal
Debasmita Swain, Akash Dey, Anushree Roy +2
Using finite temperature Raman spectroscopy, we investigate the electron-phonon interactions (EPI) and phonon-phonon scattering dynamics in the Dirac semimetal Cd3As2 in different…

Current-induced spin polarisation in Rashba-Dresselhaus systems under different point groups
Akash Dey, Ashis K. Nandy, Kush Saha
Non-magnetic materials without inversion symmetry typically exhibit strong Rashba spin-orbit coupling (SOC), enabling the well-known Rashba Edelstein effect where an external elect…
