Tutorials

This page collects the executable notebooks in one place. Use it as the main entry point once you want to run code rather than read background material.

Choosing a path

First working example

Run the quickstart notebook before diving into the longer workflows.

jaxvacua quickstart

End-to-end package tour

Follow the overview notebook to see geometry input, model construction, sampling, refinement, and analysis in one narrative.

JAXVacua: overview

Vacuum finding

Start here for Newton refinement, ISD-biased sampling, and bounded flux searches.

Finding flux vacua

Geometry and limits

Use these notebooks when you need moduli-space limits, coni-LCS expansions, or one-modulus model data.

Moduli-space limits and custom prepotentials

External workflow tutorials

The database, vacua-vault, and cluster-parallelisation tutorials have moved to the StringForge umbrella package, which hosts the shared catalogue I/O and storage layer. See the StringForge database and infrastructure tutorials.
