Abstract

The mutual interaction between Josephson plasmon and energy-gap amplitude collective oscillations in a SIS junction is considered where S denotes a superconducting electrode and I is a dielectric barrier. Using a simple tunneling model we find that both modes can be stable for a range of magnitudes of the tunneling interaction and Cooper coupling strength.
