Effective Field Theory for Atom-Molecule Systems I: Formulation of Effective Field Theory
arXiv:1109.2956
Abstract
We present a model of a coupled bosonic atom-molecule system, using the recently developed c-field methods as the basis in our formalism. We derive expressions for the s-wave scattering length and binding energy within this formalism, and by relating these to the corresponding experimental parameters, we can accurately determine the phenomenological parameters in our system.
