Magnetic properties of Hubbard model with electronic long-range jumps
Keywords:
Hubbard model, Green function, magnetic propertieAbstract
The study of systems of spins with electronic long-range jumps is an important field of research in solid state physics. It may determine the influence of the reach of the interaction on the magnetic critical behavior. In this work we use the Hubbard model with electronic long-range jumps. We apply the Green functions method using Hartree-Fock and random phase approximations to study the behavior of the energy bands and magnetic phases diagram as a function of the jumps and coulombian potential. We also obtain the critical magnetic temperature.Downloads
