Abstract
The effects of alternating magnetic field on the bipartite entanglement in an opened Ising chain are studied. Entropy is used to evaluate bipartite entanglement in the system. All-values entropy decreases with the strength of alternating field increases. The method of density matrix renormalization-group is applied to obtain logarithmic behavior of entropy. It is found that the logarithmic behavior with a central charge c does not vary with the length of the subsystem.
