Abstract

We obtain explicit characterization of spectral and orbital stability of solitary wave solutions to the U(1)\mathbf{U}(1)-invariant Klein--Gordon equation in one spatial dimension coupled to an anharmonic oscillator. We also give the complete analysis of the spectrum of the linearization at a solitary wave.
