Anomalous oscillatory magnetoresistance in superconducting transitions

TL;DR

This paper reports a universal oscillatory magnetoresistance phenomenon in superconductors, suggesting a fundamental mechanism possibly related to intrinsic pair-breaking at sub-atomic scales, independent of typical experimental parameters.

Contribution

The discovery of a nearly universal oscillatory magnetoresistance in superconductors indicates a potential fundamental mechanism beyond conventional superconductivity.

Findings

Oscillatory magnetoresistance observed across various superconducting systems.

Periodicity is independent of temperature, current, magnetic field, and material.

Suggests a fundamental, possibly sub-atomic, pair-breaking mechanism.

Abstract

We have discovered an oscillatory magnetoresistance phenomenon in a wide range of superconducting systems, with a periodicity that is essentially independent of temperature, transport current, magnetic field, and even material parameters. The nearly universal period points to a possible fundamental mechanism deeper than superconductivity itself, and may result from intrinsic pair-breaking mechanisms at sub-atomic length scales.
