Abstract

We derive a relationship between the one-dimensional density of states at energy E and the phase of the transmission amplitude at that energy by developing the two-channel S-matrix scattering theory for one-dimensional scattering and employing the relationship between traces of Green's-function operators and the on-shell S matrix.
