Quantum spin-transfer torque induced nonclassical magnetization dynamics and electron-magnetization entanglement
Priyanka Mondal, Marko D. Petrovic, Petr Plechac +1
The standard spin-transfer torque (STT)---where spin-polarized current drives dynamics of magnetization viewed as a classical vector---requires noncollinearity between electron spi…
Steady State Sensitivity Analysis of Continuous Time Markov Chains
Ting Wang, Petr Plechac
In this paper we study Monte Carlo estimators based on the likelihood ratio approach for steady-state sensitivity. We first extend the result of Glynn and Olvera-Cravioto [doi:doi:…
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…
