Machine Learning Potentials

Machine Learning Potentials in AMS

Within the Amsterdam Modeling suite several Machine Learning potentials are available such as the popular M3GNET universal potential. In combination with the AMS driver, machine learning potentials allow you to run accurate Molecular Dynamics simulations or to explore potential energy surfaces for e.g. frequency calculations or thermochemistry calculations and visualize the results with the GUI.

Training or refining your own Machine Learning potentials is possible within the dedicated parametrization environment of AMS (ParAMS). Your own (proprietery) in house ML potentials,can be used via the ASE engine, offering instant access to all AMS driver functionality such as our advanced Molecular Dynamics or potential energy exploration methods.

AMS features the following foundation models, which are applicable for a wide range of molecules/materials:

More details about these models can be found in the MLPotential documentation.

If you have trained your own machine learning potential using an external package, you may be able to couple it to the AMS Driver, GUI, and PLAMS using the AMS interface to the Atomic Simulation Environment (ASE).
