Observation of Shapiro steps in an ultracold atomic Josephson junction

This repository contains the data for the article „Observation of Shapiro steps in an ultracold atomic Josephson junction“ by E. Bernhart, M. Röhrle, V. Singh, L. Mathey, L. Amico and H. Ott. The repo contains experimental and simulation data. The main experimental data, the current- chemical potential characteristics of the Shapiro drive for different modulation frequencies and modulation amplitudes are stored as csv-files. They csv table contain the barrier velocity and atomnumber imbalance which can be processed using the methods within the provided python evaluation scripts. They are generated by evaluating the main measurement signal, absorption images, as described in the article. The data of the main text are sorted by figures, all data of the supplementary are stored in one directory, more information about the data structure can be found in the read_me. The simulation data presented in the figures are also stored as csv files,or h5 images, and the source code, as well as the evaluation files are provided within this repo.
