"Instantaneous superluminality" in a bimetallic wire consisting of a superconducting aluminum wire plated with a thick copper covering

TL;DR

This paper proposes a theoretical model where Cooper pairs in a superconducting aluminum wire with a copper cover exhibit instantaneous superluminal transfer, suggesting a form of superluminality consistent with relativity, and proposes experiments to test this.

Contribution

It introduces a theoretical framework predicting superluminal Cooper pair flow in a bimetallic superconducting wire, combining Maxwell's equations and superfluid velocity equations.

Findings

The model predicts instantaneous Cooper pair transfer across the wire.

Superluminal transfer does not violate relativistic causality.

Proposed experiments aim to verify the superluminal phenomenon.

Abstract

Maxwell's equations applied to a superconducting wire (aluminum) covered with a thick nonsuperconducting sheath (copper), in combination with the superfluid velocity equation for Cooper pairs which obeys DeWitt's minimal coupling rule, implies an instantaneous streamline flow that leads to the phenomenon of "instantaneous superluminality," in which a Cooper pair can disappear from the left end of the wire and instantaneously reappear at the right end of the wire. Relativistic causality is not violated by this superluminal phenomenon, which involves analytic, finite bandwidth waveforms whose spectrum lies below the BCS gap frequency. Experiments are proposed to test these ideas.
