Brief description This repository contains data, code, and other materials for ""Smoking gun" signatures of topological milestones in trivial materials by measurement fine-tuning and data postselection". Files are zipped by project. Data formats MTX: A simple 2D/3D matrix format developed for Spyview. DAT: Plain-text tabular data. DAT and MTX files can be plotted with Spyview, qtplot (a portable version for Windows can be downloaded here), Jupyter notebooks in ZIP files or here. SET: Instrument settings. PY: Measurement scripts. IPYNB or HTML: Jupyter notebooks with code and figures. IPYNB can be previewed on this page. Additional repositories MATLAB codes for theoretical simulations in Ref 63: https://github.com/frolovgroup/ Full data and code from the Shapiro step project: [https://zenodo.org/record/6416083](Data and code for "smash junction" papers)
