AdaptiveSimplex

Standalone native zero-temperature integration backend extracted from MeanFi.

What lives here

• the C++/nanobind runtime for adaptive simplicial zero-temperature integration,
• Python helpers that convert tight-binding dictionaries into native runtime inputs,
• backend-level tests for geometry, fixed-mu, and fixed-filling zero-temperature integration.

Local development

pip install -e .
pytest

The native extension requires a C++17 compiler, nanobind, scikit-build-core, and an Eigen3 installation discoverable by CMake.
