arXiv:2002.06556[cond-mat.supr-con]
Pair formation of two electrons by Coulomb repuslion of a square
tight-biding lattice with a bandwidth B=16 and interaction U=2; two moments
of time are shown (t = 200 (left), t= 4000 (right)); color is proportional
to electron density (red/blue for maximum/zero); diagonal density
corresponds to pair propagation, size is 128 X 128.
