Strain engineering of ultrafast magnetism in the room-temperature vdW ferromagnet Fe3GaTe2
Fan Fei, Yangchen He, Wuzhang Fang +6
Controlling ultrafast magnetic dynamics is critical to understanding nonequilibrium spin interactions and advancing high-speed spintronics. However, a lack of efficient in situ tun…

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…

Photogalvanic currents from first-principles real-time density-matrix dynamics
Junting Yu, Andrew Grieder, Jacopo Simoni +3
The photogalvanic effect is the generation of a second-order direct current by illumination of a non-centrosymmetric material. In this work, we develop a first-principles real-time…
