Abstract: (Springer)

The quantum phase transition for the q-deformed Yang-baxter Hamiltonian has been discussed. The calculation shows when the deformed parameter q approaches 1, there exists a quantum critical point for spectral parameter . In this Yang-Baxter syste m, quantum entanglement and the geometric phase can characterize quantum phase transition.
