Physicists Apply Einstein’s General Theory of Relativity to Superconducting Circuits

In recent years, UC Santa Barbara scientists showed that they could reproduce a basic superconductor using Einstein’s general theory of relativity. Now, using the same theory, they have demonstrated that the Josephson junction could be reproduced. The results are explained in a recent issue of the journal Physical Review Letters.

The Josephson junction, a device that was first discovered by Brian David Josephson in the early 1960’s, is a main ingredient in applications of superconductivity.
