Magnetic properties of low-dimensional half-filled-band Hubbard systems

Utilizing the canonical quantum Monte Carlo method we studied the thermodynamic properties of some low-dimensional half-filled-band Hubbard systems ladders type. Our results show that the magnetic susceptibility behaves drastically different depending on the numbers of legs and on the relative magni...

Summary:Utilizing the canonical quantum Monte Carlo method we studied the thermodynamic properties of some low-dimensional half-filled-band Hubbard systems ladders type. Our results show that the magnetic susceptibility behaves drastically different depending on the numbers of legs and on the relative magnitude of the Coulombian repulsion to transfer integral of the system.
