Spatio-temporal dynamics of shift current quantum pumping by femtosecond light pulse
U. Bajpai, B. S. Popescu, P. Plechac +4
Shift current---a photocurrent induced by light irradiating noncentrosymmetric materials in the absence of any bias voltage or built-in electric field---is one of the mechanisms of…

Spin and charge pumping by steady or pulse current-driven magnetic domain wall: A self-consistent multiscale time-dependent-quantum/time-dependent-classical approach
Marko Petrovic, Bogdan S. Popescu, Utkarsh Bajpai +2
We introduce a multiscale framework which combines time-dependent nonequilibrium Green function (TD-NEGF) algorithms, scaling linearly in the number of time steps and describing qu…
