โœฆ Synopsis


Two possible strategies of experimental observation of the Bloch oscillations with frequency f=I/2e in ultrasmall Josephson tunnel junctions are analyzed. The analysis shows that the effect can be observed in junctions of conventional superconductors, using both the high-ohmic-resistor and normal-junction-array schemes of the dc biasing.
