Welcome to the documentation for TBTK!

TBTK is an open-source C++ framework for modeling and solving problems formulated using the language of second quantization. It can be used to set up general models with little effort and provides a variety of native solution methods.

To get started, see the installation instructions, manual, examples, and tutorials. Also, see the blog posts and other resources collected on second-tech.com.

Download TBTK

Download TBTK from GitHub. See the installation instructions to make sure you checkout the right version before installation.

Core strengths

  • The speed of a low-level language with the syntax of a high-level language.
  • Results in readable code that puts emphasis on the physics.
  • Allows for a wide variety of models and solution methods to be combined in different ways.
  • Focus on your own task, while still benefiting from the work of others.
  • Gives method developers complete freedom to optimize their solvers without having to worry about model-specific details.
  • A versioning system that ensures that results are reproducible forever.
