Equation of motion approach to non-adiabatic quantum charge pumping
Equation of motion approach to non-adiabatic quantum charge pumping
We use the equations of motion of non-interacting electrons in a one-dimensional system to numerically study different aspects of charge pumping.We study the effects of the pumping frequency, amplitude, band filling and finite bias on the charge pumped per cycle, and the Fourier transforms of the charge and energy currents …
