Phase diagram of a generalized Penson–Kolb–Hubbard chain with the occupation-dependent hopping
At half filling, we study analytically a one-dimensional correlated electronic system modeled by an extended Penson–Kolb–Hubbard (PKH) chain with the occupation-dependent hopping. The modification of the electron hopping amplitude is exhibited to induce the additional correlated-hopping interactions...
