Record dynamics and the observed temperature plateau in the magnetic creep rate of type II superconductors

TL;DR

This paper explains the temperature plateau in the magnetic creep rate of type II superconductors using Monte Carlo simulations and record dynamics, revealing a stochastic process underlying the phenomenon.

Contribution

It introduces record dynamics as a novel explanation for the temperature independence of the creep rate in superconductors.

Findings

Record dynamics explains the temperature plateau in creep rates.

Monte Carlo simulations support the record dynamics model.

The approach links stochastic record events to physical properties of superconductors.

Abstract

We use Monte Carlo simulations of a coarse grained three dimensional model to demonstrate that the experimentally observed approximate temperature independence of the magnetic creep rate for a broad range of temperatures may be explained in terms of record dynamics, {\it viz.} the dynamical properties of the times at which a stochastic fluctuating signal establishes records.
