- A new lattice model is presented for correlated electrons on the unrestricted 4$\text{}^{L}$-dimensional electronic Hilbert space ⨁$\text{}_{n=1}^{L}$C$\text{}^{4}$ (where L is the lattice length). It is an extension of the supersymmetric t-J model. The new model has gl(2|1) supersymmetry and contains one symmetry-preserving free real parameter α which has its origin in the one-parameter family of inequivalent typical 4-dimensional irreps of gl(2|1). When α = 0, the model reduces to the supersymmetric t-J model.
