The model considered here is inspired by a Lipkin-Meshkov-Glick model of $\\Omega$ particles distributed into two bands of energy and coupled by a two-body interaction. Such a model can be exactly solved (numerically though) for small $\\Omega$. It therefore allows a direct comparison of STDHF and the exact propagation.
