This program is a dynamics solver for open quantum systems, mainly based on the dissipaton equation of motion (DEOM) formalism. The code is written in C++ and uses Python being the input script generator.
Dissipaton equation of motion (DEOM) is an exact approach for open quantum systems with Gaussian environment ansätz. It is a second quantization generalization of the hierarchical equations of motion (HEOM), a derivative equivalence of the well known Feynman-Vernon influence functional formalism.
