Friction does not exist at the atomic level according to current atomic physics models, which align with established quantum mechanics principles. The concept of friction emerges in many-particle systems, such as atomic lattices in macroscopic solids. These models predict that irregularities in the atomic structure, like jagged surfaces, can lead to significant friction when interacting with other materials. Thus, while friction is a macroscopic phenomenon, it is not applicable at the atomic scale.
