Talk:Josephson energy

Classification is wrong. Josephson energy has nothing to do with a large scale energy production.

Citation: "The Josephson Inductance is also known as a Kinetic Inductance - the behaviour is derived from the kinetic energy of the charge carriers, not energy in a magnetic field." I, personally, am not sure that this is so.

• Kinetic inductance is related to kinetic energy of the superconducting electrons (Cooper pairs) and should scale ${\displaystyle \propto I^{2}}$. The Josephson inductance does not.
• Also, the kinetic energy of the electrons in the superconducting electrodes is not smaller than in the JJ itself. However, we usually neglect electrode energy as it is much smaller than the one of JJ.
• Finally, Josephson energy is a potential energy....so it suggests that the phase difference ${\displaystyle \phi }$ is of primary importance, rather than the current ${\displaystyle I_{s}}$. — Preceding unsigned comment added by EdwardGoldobin (talk • contribs) 09:08, 31 January 2014 (UTC)[reply]
