## 2. Packages we develop(ed)
* <a target="_new" href="https://quantum-dynamics-hub.github.io/libra/index.html"><b>Libra</b></a>
is the "methodology development" library we actively develop in the group.
It is intended for various types of calculations in quantum and classical chemical dynamics
and beyond. Learn more about this code on its website (follow the link).
The latest release is here:
[](https://zenodo.org/badge/latestdoi/101275719)
* <a target="_new" href="https://github.com/Quantum-Dynamics-Hub/pyxaid-code"><b>PYXAID</b></a>
is an older (although still in use by some groups) tool for nonadiabatic quantum dynamics (NAQD)
in atomistic systems, developed by Akimov and Prezhdo. The code website (follow the link) contains detailed step-by-step tutorials.
The tutorials cover basic and advanced topics related to practical utilization of the code. They also cover some basics
of calculations with the QE code.
NOTE: we don't really develop or support this tool, since more advanced and consistent calculations can be done with Libra.
* <a target="_new" href="https://github.com/Quantum-Dynamics-Hub/pyxaid2"><b>PYXAID2</b></a>
is a version co-developed with Dr. Wei Li, to include NACs calculations with orbitals given in a two-component spinor format.
NOTE: these capabilities are currently included in Libra
