Solutions to the Multi-Component 1/R Hubbard Model
arXiv:cond-mat/9305042 · doi:10.1103/PhysRevB.48.10556
Abstract
In this work we introduce one dimensional multi-component Hubbard model of 1/r hopping and U on-site energy. The wavefunctions, the spectrum and the thermodynamics are studied for this model in the strong interaction limit . In this limit, the system is a special example of Luttinger liquids, exhibiting spin-charge separation in the full Hilbert space. Speculations on the physical properties of the model at finite on-site energy are also discussed.
