The Critical Role of Itinerant Contributions to Orbital Angular Momentum Relaxation and Dynamics
Andrew C. Grieder, Luis M. Canonico, Frederico Simões +2
Orbital angular momentum (OAM) is a promising degree of freedom for low-dissipation transport and magnetization control, yet its relaxation mechanisms remain controversial, with at…

Open-quantum-system theory of non-Markovian electron-phonon dynamics
Gabriele Riva, Jacopo Simoni, Yuan Ping
We present a non-Markovian open-quantum-system formalism for nonequilibrium electron-phonon dynamics: a closed set of five coupled equations of motion, derived directly from the de…

Chirality-Induced Spin Selectivity: Nonlinear Spin Response from Electron-Phonon Scattering
Mayank Gupta, Andrew Grieder, Mayada Fadel +4
Chirality-induced spin selectivity (CISS) generates spin-polarized currents in nonmagnetic materials from structural chirality alone, yet its microscopic origin remains debated. Us…
