The phase synchronization of an axion and a superconductor

TL;DR

This paper explores how axion fields may influence superconductors, particularly through phase synchronization, potentially affecting the London penetration depth and offering a new avenue for axion detection.

Contribution

It introduces a novel perspective on axion-superconductor interaction by linking axion phase synchronization to Josephson junction behavior and superconducting properties.

Findings

Axion mass may affect the London penetration depth.

Phase synchronization between axions and superconductors is possible.

Detection of axion effects is more feasible in low carrier density superconductors.

Abstract

The effects of the axion field have been widely studied in theoretical physics, particularly in particle physics. Considering the phase synchronization and the mean free path of the axion, the bulk of the phase coherent superconductor is regarded as the weak link region of the Josephson junction.It is expected that the axion mass influences the London penetration depth.There is a slight possibility of detecting this effect because the effect becomes more significant in superconductor with a low carrier density $n_s$.The differences due to the choice of axion model and the axion mass are discussed.
