Mattis, Daniel C. | Eigenstates of N excitons and one hole | We solve for the eigenstates and energy eigenvalues of N immobile Frenkel excitons (a relatively trivial proposition) and of N such excitons plus one hole (which for large N can only be done in one dimension). We also guess that a charged globule, consisting of N excitons and O(N) holes, can be stab... | Eigenstates; Frenkel excitons; Many-body problem | 1983-04 |

Mattis, Daniel C. | Nonlinear lattice dynamics in two dimensions | In general, dynamical and quantum-mechanical properties of anharmonic lattices are best expressed in terms of bond variables. A transformation from atomic (site) to bond coordinates is generated in two dimensions, with the help of a number of subsidiary conditions expressed on plaquettes. It is sho... | Phonons; Plaquettes; Harmonic oscillators; Ferromagnets | 1983-04 |
