Solution of three-dimensional Faddeev equations: ultracold Helium trimer calculations with a public quantum three-body code

摘要

We present an illustration of using a quantum three-body code being preparedfor public release. The code is based on iterative solving of thethree-dimensional Faddeev equations. The code is easy to use and allows usersto perform highly-accurate calculations of quantum three-body systems. Thepreviously known results for He$_3$ ground state are well reproduced by thecode.
