User guide

Welcome to the TRIQS project!

This guide aims at presenting you the main classes of TRIQS and its applications through ready-to-use examples. These small demo codes should help you understand the logic behind the general design and organization of the library.

Note

We strongly recommend first-time users to go through the extensive set of Jupyter Notebook tutorials provided on GitHub. You can run the notebooks either in an interactive Binder Session on the web or run them locally after setting up TRIQS on your computer.

Warning

This pages does not aim to replace the full reference of the code available here.

Why use TRIQS?

TRIQS is a powerful library that allows you to easily write code to study strongly correlated problems. It is designed as a toolkit containing all the essential ingredients to tackle condensed matter physics. Before presenting you the tools available both in C++ and Python, we want you to have a look at a small script where a full Dynamical Mean-Field Theory calculation using the Continuous-Time Hybridization Expansion (CT-HYB) solver is realized in… one page!

• Dynamical mean-field theory on a Bethe lattice

A quick tour in Python

We here provide a little tour of some aspects of TRIQS and its applications, at the Python level.

• Local Green’s functions
• Lattice Green’s functions
• Multivariable Green’s functions
• HDF5 archives
• A tight-binding model on a square lattice

If you want to learn more about Python, iPython and the notebook, you can check our external resources:

A quick tour in C++

We here provide a little tour of some aspects of TRIQS and its applications, at the C++ level.

• Green’s functions
• Multidimensional arrays
• Determinants for Continuous-Time Monte-Carlo
• Green’s function and HDF5 files
