| 内容記述 | We consider the contribution of the amplitude mode to the damping rate of the Josephson plasmon. When a finite phase difference is present owing to the super-current through the junction, the broken time-reversal symmetry causes a finite coupling between the Josephson plasmon and amplitude mode. The strength of this coupling varies depending on the value of the phase difference, and the effect of the amplitude mode on the damping rate also depends on this phase difference. The damping rate becomes larger with increasing this coupling, and this results in the phase-difference dependence which is opposite to that obtained with use of the dissipation current due to quasiparticles by the previous theory. This effect leads to a theoretical explanation for previous experiments, including the damping rate near the transition temperature. | |||||||||||
