  • Qbox is a first principles molecular dynamics (MD) code using Density Functional Theory (DFT) and hybrid-DFT. In addition to the simulation of thermodynamic and structural properties of materials, Qbox allows for the calculations of vibrational spectra, ionic conductivity and heat transport coefficients.
  • WEST performs large-scale many-body perturbation theory calculations providing electronic and optical spectroscopic characterization of complex materials.
  • PySAGES is a GPU-enabled version of SSAGES. PySAGES and SSAGES provide a comprehensive suite of advanced methods for phase space sampling organized into a unified framework that can be used as a wrapper for quantum and classical MD and Monte Carlo (MC) engines. They are coupled with several MD and electronic structure codes.
  • PyCCE (code repository) is an open-source python library to simulate the dynamics of spin qubits interacting with a spin bath using the cluster-correlation expansion (CCE) method.
  • PyZFS (code repository), PyEPFD (code repository), PyPL (code repository) , and PyRET (code repository) are python packages coupled to first principles simulations and electronic structure calculation engines. PyZFS is used for the calculation of the zero-field splitting (ZFS) tensor, D, of molecules and solids, based on wavefunctions obtained from density functional theory calculations. PyEPFD is a Python library to compute electron-phonon interactions from finite displacements (using either frozen phonon and or stochastic methods) and to analyze molecular dynamics trajectories and determine electron-phonon interactions. PyPL computes vibrationally resolved optical spectra of point defects using atomic positions and phonons obtained from DFT calculations. PyRET enables calculations of non-resonant energy transfer processes.
