A new tow-parameter integrable model of strongly correlated electrons with quantum superalgebra symmetry
Abstract
A new two-parameter integrable model with quantum superalgebra Uq[gl(3|1)] symmetry is proposed, which is an eight-state electron model with correlated single-particle and pair hoppings as well as uncorrelated triple-particle hopping. The model is solved and the Bethe ansatz equations are obtained.
