Spectra of pinned charge density waves with background current

Description

We develop techniques which allow us to calculate the spectra of pinned charge density waves with background current in one-dimensional space. We show that in such systems the low-lying modes are always localized, and we compute their spectral density and the localization length. We also show that as the energy is increased, the modes delocalize in a way similar to that in the Hatano-Nelson non-Hermitian quantum mechanics
