Floquet scattering in parametric electron pumps
Floquet scattering in parametric electron pumps
A Floquet scattering approach to parametric electron pumps is presented and compared with Brouwer's adiabatic scattering approach [Phys. Rev. B 58, R10 135 (1998)] for a simple scattering model with two harmonically oscillating \ensuremath{\delta}-function barriers. For small strength of oscillating potentials these two approaches give exactly equivalent results while for …
