Intense femtosecond laser excitation can produce transient states of matter that would otherwise be inaccessible to laboratory investigation. At high excitation densities, the interatomic forces that ...

A study in Nature Communications by Michele Ceriotti’s group at EPFL has introduced a new dataset and model that greatly improve the efficiency of machine-learning interatomic potentials (MLIPs) and ...

The interatomic potential describes the interaction between a pair of atoms or the interaction of an atom with a group of atoms in a condensed phase. The potential must have both an attractive and a ...
