Excitons in the strong coupling limit of the one-dimensional extended Hubbard model

Excitons in the strong coupling limit of the half-filled one-dimensional extended Hubbard model with 1/r interactions are studied. Unlike the situation for nearest neighbor interactions, where there is at most only one (doubly degenerate) bound state, a 1/r interaction results in an infinite number...
