Few-body systems

Few-body systems

In quantum mechanics and classical mechanics, a few-body system consists of a small number of well-defined structures.

In quantum mechanics, examples of few-body problems include light nuclear systems (that is, few-nucleon bound and scattering states), small molecules, light atoms (such as helium in an external electric field), and quantum dots. Three-body systems can be solved exactly through the Faddeev equations.

In classical mechanics, the few-body problem is a subset of the N-body problem.

One notable journal covering this field is "Few-body Systems".
