Controllable Amplification of Entanglement for Two Qutrits under Decoherence

【摘要】 <正> Entanglement dynamics of a two-qutrit Heisenberg spin chain with the external magnetic fields and DMinteraction under the intrinsic decoherence is investigated.Depending on whether there is inhomogeneous magnetic field,the entanglement amplification,i.e.the phenomenon that the finally stable entanglement is bigger than that of the initialone,is found for one kind of initial states.The reasons for the controllable entanglement amplification are discussed.更多还原
