✦ Synopsis
A study has been carried out on the nonlinear nature of Anderson plasma excitations in narrow Josephson junctions in case of a longitudinal ultrasonic wave propagating normal to the tunnel barrier plane with a frequency resonant to the plasma oscillation frequency in the junction. A high frequency current associated with a sound-induced displacement of Anderson plasma energy levels was shown to be excited across the junction. The problem of sound wave attenuation and amplification is discussed and an attempt is made to predict the effect of amplification of ultrasonic waves passing through the junction.
