Abstract
The ground-state Mott transition of the Hubbard model on the Bethe lattice with an infinite coordination number is investigated. The system is mapped to a numerically tractable finite model according to the proposal by Si et al. The intersection points of curves of our new order parameter with a varying mapping precision are found to yield a systematic estimate of the Mott transition point. The meaning of the order parameter is investigated. The White method is applied in order to examine very large mapped systems approximately. Transition properties are discussed in detail.
