This is the C++ documentation of TRIQS/TRIQS v4.0.0. The source code can be found on GitHub and the official website at https://triqs.github.io/triqs.

TRIQS (Toolbox for Research on Interacting Quantum Systems) is a scientific software library providing various building blocks that facilitate the implementation and developement of new tools and algorithms for the study of interacting quantum systems.

We provide efficient implementations in C++ and expose its functionality through high-level interfaces in Python. This paradigm allows our users to quickly develop new ideas and algorithms, while benefiting from the performance of a compiled language.

This website is generated with Doxygen and focuses only on the C++ part of the library.

For general information on TRIQS and documentation for its Python interface, we refer the reader to the official website.

Where to start?

The Installation section tells you how to get the library and make it available on your system.

Integration in C++ projects explains how to integrate TRIQS in your own C++ code.

Then, you can start with the Examples section to get an overview of the library's features and how TRIQS can be used in practice.

Furthermore, we provide a detailed reference API Documentation to answer your questions.
