 abstract = {Using a tight-binding model, we study one-parameter charge pumping in a
one-dimensional system of noninteracting electrons. An oscillating
potential is applied at one site, while a static potential is applied in
a different region. Using Floquet scattering theory, we calculate the
current up to second order in the oscillation amplitude and exactly in
the oscillation frequency. For low frequency, the charge pumped per
cycle is proportional to the frequency and, therefore, vanishes in the
adiabatic limit. If the static potential has a bound state, we find that
such a state has a significant effect on the pumped charge if the
oscillating potential can excite the bound state into the continuum
states or vice versa. Finally, we use the equation of motion for the
density matrix to numerically compute the pumped current for any value
of the amplitude and frequency. The numerical results confirm the
unusual effect of a bound state.},
