WebThe simplest way to analyze the Bloch-wave oscillations turns out to be a Langevin-type equation for the operator of the junction “quasicharge” q. In particular, this equation shows that the frequency f B of these oscillations is related by the fundamental equation f_B = (\bar I - G\bar V)/2e to the dc current \bar I and voltage \bar V.
