    • It was also suggested that a continuous transition takes place in the infinite-dimensional Hubbard model [J. Schlipf, M. Jarrell, P.G.J. van Dongen, N. Blümer, S. Kehrein, T. Prushke, D. Vollhardt, Phys. Rev. Lett. 82, 4890 (1999)], but an accurate treatment of reference [17] gives the phase coexistence in the low temperature regime and shows that this transition is first order

    • As a consequence of the local self-energy, the Green's functions found along the AF BZ are degenerate in the DMFT, while in reality they are only nearly degenerate, as obtained in the 2D-QMC method

    • note
    • This hysteresis appears in a range of U values in which two locally stable solutions of the DMFT equations exist: a global minimum for the antiferromagnetic state, and a local minimum for the paramagnetic state
