Metal–Insulator Transition in the Presence of Van Hove Singularities for Bipartite Lattices
We have considered the phase diagram of the ground state for the t – t ' Hubbard model with half-filling of the band. The criterion for the metal–insulator transition has been formulated using the analytic expansion in transfer integral t ' and in direct antiferromagnetic gap Δ. For a squa...

' Hubbard model with half-filling of the band. The criterion for the metal–insulator transition has been formulated using the analytic expansion in transfer integral
t
' and in direct antiferromagnetic gap Δ. For a square lattice, there exists an interval of
t
' values for which the metal–insulator transition is of the first order due to the existence of the Van Hove singularity. For simple and body-centered cubic lattices, a transition occurring from the insulator antiferromagnetic state to the antiferromagnetic metal phase is a second-order transition followed by a transition to paramagnetic metal. |
