A possibility of emission of high frequency gravitational radiation from d-wave to s-wave type superconductor junctions

TL;DR

This paper explores the potential for high-frequency gravitational radiation emission from superconductor junctions involving d-wave and s-wave Cooper pairs, especially under non-equilibrium conditions, suggesting a novel gravitational interaction mechanism.

Contribution

It proposes that SDS superconductor junctions can emit gravitational radiation under non-equilibrium conditions, a new theoretical insight into superconductor-gravity interactions.

Findings

No net gravitational emission in equilibrium conditions.

Gravitational radiation emitted under non-equilibrium conditions.

Possible explanation for gravitational effects observed in high-Tc superconductor experiments.

Abstract

Recent measurements on a class of high-Tc superconductors (HTSC) have shown that Cooper-pairs binding may be associated to a d-wave, while in another class, d and s waves may coexist. When d-wave Cooper-pairs are injected in a superconductor that can sustain s-wave binding, d-wave pairs decay to s-wave pairs and energy is irradiated by means of gravitons. We show that in s-wave to d-wave type superconductor (SDS) junctions in an equilibrium condition no net gravitational wave energy is emitted, on the other hand under non equilibrium conditions a net gravitational wave energy is emitted by the junction. Experiments which show a gravitational interaction between inomogeneus high-Tc superconductors, under non equilibrium conditions, and test objects may be understood by accepting a possibility of emission of gravitational radiation from SDS junctions.
