论文摘要
我们探索与热耗散环境接触的两级系统中环境诱导的同步现象。我们首先讨论一对两级粒子之间同步出现的条件。也就是说,我们分析了各种模型参数对(反)同步的出现的影响,例如环境温度,粒子之间的直接相互作用以及控制耗散集体的距离。然后,我们扩大了由三个两级原子组成的系统,以研究不同粒子对之间的相互同步。值得注意的是,在这种情况下,我们观察到了丰富的同步动力学,该动力学源于原子的不同可能的空间构型。特别是,与两种原子的情况形成鲜明对比,我们表明,当三个原子处于近距离接近时,由于挫败感,在所有粒子对上都可以阻塞反同步的出现。
We explore the environment-induced synchronization phenomenon in two-level systems in contact with a thermal dissipative environment. We first discuss the conditions under which synchronization emerges between a pair of two-level particles. That is, we analyze the impact of various model parameters on the emergence of (anti-)synchronization such as the environment temperature, the direct interaction between the particles, and the distance between them controlling the collectivity of the dissipation. We then enlarge the system to be composed of three two-level atoms to study the mutual synchronization between different particle pairs. Remarkably, we observe in this case a rich synchronization dynamics which stems from different possible spatial configurations of the atoms. Particularly, in sharp contrast with the two-atom case, we show that when the three atoms are in close proximity, appearance of anti-synchronization can be obstructed across all particle pairs due to frustration.
