dc.description.abstractSome new Hamiltonians are constructed via the unitary Yang-Baxter matrices Ři,i+1 (θ, φ) acting on a Hamiltonian H0 which describes nearest spin-spin interaction. By the concept of concurrence, we explore the thermal entanglement of these systems. We find that the interaction of z-component of two neighboring spins g has great influences on the thermal entanglement. It not only influences the critical temperature Tc, but can also influence the critical magnetic field Bc. © 2009 World Scientific Publishing Company.
