The quantum phase transition for the “q-deformed” Yang-baxter Hamiltonian has been discussed. The calculation shows when the deformed parameterqapproaches 1, there exists a quantum critical point for spectral parameterθ. In this Yang-Baxter system, quantum entanglement and the geometric phase can characterize quantum phase transition.
