The high numerical cost of quantitative ab-initio methods restricts their application to small systems, composed of a few hundred atoms, limiting the ability to study larger molecular systems. As an alternative, force fields (FFs) have emerged as valuable tools, employing physically-motivated functional forms to model potential energy surfaces. These FFs are parameterized to match ab-initio as well as experimental data, offering a computationally cheaper alternative for simulating diverse systems, ranging from biology to polymers and complex materials. Indeed, there is a wide range of FFs developed for different purposes and compounds.
