Electron pairing by Coulomb repulsion in narrow band structures
by K.M.Frahm and D.L.Shepelyansky

Pair formation of two electrons by Coulomb repuslion of a square tight-biding lattice (left) and La-cuprate lattice (right) at U=2 and certain time moment; lattive size is 128 X 128; density is projected to x_1,x_2 plane.
