| Abstract: | This paper investigates the entanglement in an XX-type spin chain with Dzyaloshinskii---Moriya interaction under an external magnetic field. The von Neumann entropy of entanglement between two blocks for the ground state of the system is evaluated. It analyses and discusses the scaling behaviour of the entanglement entropy. |
