+
+N2
+--
+
+Machine-learned interatomic potential specifically designed to study the phase diagram of N₂ up to 10 GPa. The model requires the Tadah!LAMMPS plugin to be installed (:ref:`installation_lammps`).

+`Understanding solid nitrogen through molecular dynamics simulations with a machine-learning potential <https://doi.org/10.1103/PhysRevB.110.184107>`_
+
+Kr
+--
+
+A two-body interatomic potential that performs exceptionally well given its simplicity. Two versions are provided. The first model (`Tadah!Kr1`) was fitted to CCSD(T) dimers, while the second model's energies were corrected using equilateral Kr trimers (`Tadah!Kr2`).
+
+Both potentials are provided in two formats: the native Tadah! format, which requires the Tadah!LAMMPS plugin (:ref:`installation_lammps`), and a tabulated potential formatted for LAMMPS pair_style table.
