论文摘要
我们探讨了具有非本地耗散的量子几体旋转系统中的同步现象。没有外部驾驶，我们发现该系统可以在长期动力学中表现出稳定的振荡行为，并伴随着Liouvillian纯粹虚构特征值的出现。此外，下一新的邻居旋转的振荡完全同步通过随机schrödinger方程中的量子轨迹分析揭示。还讨论了通过簇平均近似值在无限大小晶格中长期振荡出现的可能性。
We explore the synchronization phenomenon in the quantum few-body system of spins with the non-local dissipation. Without the external driving, we find that the system can exhibit stable oscillatory behaviors in the long-time dynamics accompanied by the appearance of the purely imaginary eigenvalues of the Liouvillian. Moreover, the oscillations of the next-nearest-neighboring spins are completely synchronized revealed by the quantum trajectory analysis within the stochastic Schrödinger equation. The possibility of the appearance of the long-time oscillations in infinite-size lattice by means of cluster mean-field approximation is also discussed.
