Green's Functions and the Adiabatic Hyperspherical Method
Abstract
We address the few-body problem using the adiabatic hyperspherical representation. A general form for the hyperangular Green's function in d-dimensions is derived. The resulting Lippmann-Schwinger equation is solved for the case of three-particles with s-wave zero-range interactions. Identical particle symmetry is incorporated in a general and intuitive way. Complete semi-analytic expressions for the nonadiabatic channel couplings are derived. Finally, a model to describe the atom-loss due to three-body recombination for a three-component fermi-gas of 6Li atoms is presented.
