Generalized t-j model
Shao-Ming Fei, Rui-Hong Yue
Abstract
By parametrizing the t-j model we present a new electron correlation model with one free parameter. In one dimension, this model is of SU q (1 mod 2) symmetry. The energy spectra are shown to be modulated by the free parameter in the model. The solution and symmetric structures of the Hilbert space, as well as the Bethe ansatz approach, are discussed for special cases.
