![]() | Mattis, Daniel C. | Few-body problem on a lattice | The author explores some of the inherent simplifications of "quantum lattice physics." He distinguishes between fermions and bosons and analyzes the n-body problem for each, with n = 1,2,3... typically a small number. With delta-function (zero-range) interactions, the three-body problem on a lattice... | Quantum; Electrons; Spin | 1986 |
