Josephson phase
Encyclopedia
In superconductivity
, the Josephson phase is the difference of the phase
s of the quantum mechanical wave function in two superconducting electrodes forming a Josephson junction.
For example, if the macroscopic wave functions
and 
in superconductors 1 and 2 are given by
then the Josephson phase is
.
Superconductivity
Superconductivity is a phenomenon of exactly zero electrical resistance occurring in certain materials below a characteristic temperature. It was discovered by Heike Kamerlingh Onnes on April 8, 1911 in Leiden. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum...

Phase (waves)
Phase in waves is the fraction of a wave cycle which has elapsed relative to an arbitrary point.-Formula:The phase of an oscillation or wave refers to a sinusoidal function such as the following:...
