Magnetic properties of the Hubbard model with an infinite repulsion on a rectangular anisotropic lattice
E. V. Ezerskaya, Vladyslav O. Cheranovskii
Hubbard’s model with an infinite repulsion on a rectangular anisotropic lattice with Ln-center segments is analyzed. For lattices with L + 1 electrons and cyclic boundary conditions, an exact dependence is obtained between the lattice dimensions and critical values of the Hubbard Hamiltonian parameters at which the ferromagnetic order is violated.
