Enhancement of charge ordering by the zeeman effect in one-dimensional molecular conductors

The effects of an external magnetic field on the charge-ordered state are investigated within the one-dimensional extended Hubbard model with a quarter-filled band. We find that the external magnetic field leads to a coexistent state with three order parameters, i.e. , the charge ordering, the unifo...

Summary:The effects of an external magnetic field on the charge-ordered state are investigated within the one-dimensional extended Hubbard model with a quarter-filled band. We find that the external magnetic field leads to a coexistent state with three order parameters, i.e. , the charge ordering, the uniform, and the staggered magnetic moments. In addition, the amplitude of the charge ordering is shown to be enhanced by the magnetic field.
