# Damping in a Superconducting Mechanical Resonator

## TL;DR

This paper investigates how superconductivity affects mechanical damping in an aluminum resonator, observing a sharp decrease in damping below the critical temperature and comparing results with BCS theory.

## Contribution

It provides experimental evidence of damping reduction in a superconducting mechanical resonator and compares findings with BCS theory predictions.

## Key findings

- Damping drops sharply below the critical temperature
- Experimental results align with BCS theory predictions
- Superconductivity influences mechanical damping behavior

## Abstract

We study a mechanical resonator made of aluminum near the normal to super conductivity phase transition. A sharp drop in the rate of mechanical damping is observed below the critical temperature. The experimental results are compared with predictions based on the Bardeen Cooper Schrieffer theory of superconductivity and a fair agreement is obtained.
