Sine model

Pumping in a periodic space crystal:

Same as above, this time using the Wannier states of the tight-binding Hamiltonian:

Delta model

Pumping in a periodic space crystal:

Pumping in a non-periodic space crystal, using the coresponding tight-binding model:

Periodic time-space pumping (two pumping cycles are shown):
