Mattis, Daniel C. | Eigenfunction localization in dilute lattices of various dimensionalities | As a fraction of bonds p is removed from a lattice, we find a threshold PQ above which all eigenstates are nonpropagating (Anderson localized). This occurs well before the classical percolation threshold. For example, in two dimensions where the classical threshold is pc = 1/2 , we find PQ = 0. | Eigenstates; Dilute lattices | 1981-05 |

Bromley, Benjamin C. | Eigenspectral computtations for linear gravity and nonlinear toy models | The periodic standing-wave approach to binary inspiral assumes rigid rotation of gravitational fields and hence helically symmetric solutions. To exploit the symmetry, numerical computations must solve for "helical scalars," fields that are functions only of corotating coordinates, the labels on the... | Binary black holes; General relativity; Standing wave | 2006 |

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 |
