In chiral superconductors, rotation looks like voltage, and geometric curvature looks like magnetic field.
In chiral superconductors, rotation looks like voltage, and geometric curvature looks like magnetic field.
In this paper, we consider a number of effects due to the interplay of superconductivity, electromagnetism and elasticity, which are unique for thin membranes of layered chiral superconductors. Some of them should be within the reach of present technology, and could be useful for characterizing materials. More speculatively, the enriched control of Josephson junctions they afford might find useful applications.
According to our theory, relative motion between two chiral superconductors generates an effective Josephson voltage. The rotating Josephson junction works as an ideal electricity generator that converts mechanical energy to electrical power without any internal ohmic dissipation.
Magnetic flux can modify tunneling current of a traditional Josephson junction. Here, we show that geometric curvature could modify a Josephson tunneling current for chiral superconductors.
