Noise Induced Intermittency in a Superconducting Microwave Resonator

TL;DR

This paper investigates how noise causes intermittent switching between different states in a superconducting microwave resonator, combining experimental and numerical approaches to understand the phenomenon.

Contribution

It introduces a theoretical model explaining noise-induced intermittency in a superconducting resonator, supported by experimental and numerical evidence.

Findings

Noise causes the system to jump between steady-state and limit-cycle responses.

The theoretical model partially explains the experimental observations.

Experimental and numerical results show noise-induced intermittency in the resonator.

Abstract

We experimentally and numerically study a NbN superconducting stripline resonator integrated with a microbridge. We find that the response of the system to monochromatic excitation exhibits intermittency, namely, noise-induced jumping between coexisting steady-state and limit-cycle responses. A theoretical model that assumes piecewise linear dynamics yields partial agreement with the experimental findings.
