Hybrid and hierarchical approach to study molecular systems in complex environments. We combine three different approaches and tools in computational chemistry: quantum dynamics (Quantics/MCTDH), quantum mechanics (Q-Chem), and molecular mechanics (Gromacs). To ensure a seamless interaction between software packages, we previously developed PySurf (framework for database accelerated direct dynamics, hosting a surface point provider as its core that communicates with a neural network plugin), INAQS (generic QM/MM interface for non-adiabatic dynamics) and Q-Force (automated tool to generate quantum mechanically derived force fields).
