Popis: | We discuss the spontaneous magnetism of electrons constrained to the corners of a square plaquette, with a view to applications in molecular physics and nanotechnology. The special cases of three or five electrons have a ground-state level-crossing in strong-coupling, U > 18t, where the ground-state of maximal spin (S = 3/2) overtakes that of minimum spin (S = 1/2). |
