Direct energy dissipation measurements for a driven superfluid via the harmonic-potential theorem
Abstract
This repository contains the experimental data and corresponding processing code for the paper Direct energy dissipation measurements for a driven superfluid via the harmonic-potential theorem arXiv:2508.15626. The raw imaging data is stored in the folder "DnD_data". The jupyter notebook 'DnD_public.ipynb' in "DnD" applies functions from the python files 'DnD_utils.py' and 'DnD.py' to proces the raw data, store it in separate datafiles linked to the separate stirrer strengths, and recreate the experimental data-plots from the publication using those datafiles. Pre-processed datafiles are already present in the folder "DnD", removing the need to download the data in "DnD_data".
