  We study electron pumping in the strong coupling and non-Markovian regime.
Our model is a single quantum dot with periodically modulated energy and
tunnelling amplitudes. We identify four parameters to control the direction of
the current: the driving phase, the coupling strength, the driving frequency
and the location of the maxima of the spectral density. In the high-frequency
regime, we use a Markovian embedding strategy to map our model to three serial
quantum dots weakly coupled to the reservoirs allowing us to use a Floquet
master equation. We observe a rectification effect of the pumped charge that is
exclusive to the non-Markovian character of our model. In the low-frequency
regime, we apply an additional transformation to see our model as three
independent transport channels. With the use of full counting statistics, we
study charge fluctuations and validate that our model behaves as a single
electron source.
