Abstract
Establishing the completeness of a Bethe Ansatz solution for an
exactly solved model is a perennial challenge, which is typically
approached on a case by case basis. For the rational, spin-1/2
Richardson–Gaudin system it will be argued that, for generic values of
the system’s coupling parameters, the Bethe states are complete. This
method does not depend on knowledge of the distribution of Bethe roots,
such as a string hypothesis, and is generalisable to a wider class of
systems.
