    • 〈k〉=0 was used to signal the Mott transition within the Gutzwiller approximation of the fermion Hubbard model, but more recent work has emphasized this is not an appropriate criterion. For results on the behavior of 〈k〉 at the Mott insulator transition in the boson Hubbard model see G. G. Batrouni, R. T. Scalettar and G. T. Zimanyi, Phys. Rev. Lett. 65, 1765 (1990).
