研究了内禀退相干下二量子体海森堡自旋链与外部磁场和DM相互作用的纠缠动力学。根据是否存在不均匀磁场,对于一种初始态会出现纠缠放大现象,即最终稳定的纠缠比初始稳定的纠缠更大的现象。讨论了可控纠缠放大的原因。
Entanglement dynamics of a two-qutrit Heisenberg spin chain with the external magnetic fields and DM interaction 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 initial one, is found for one kind of initial states. The reasons for the controllable entanglement amplification are discussed.
