论文摘要
在这项研究中，我们使用$ l_1 $ - norm连贯性的概念来表征两个 - Qutrit Heisenberg XXZ模型的纠缠，以符合均匀的磁场和Z-轴 - 轴 - dzyaloshinskii-Moriya与鲱鱼 - 菲克偶联的互动。我们显示温度，磁场，DM相互作用以及鲱鱼闪光耦合的距离都可以控制纠缠。但是，状态系统在高温或强磁场上纠缠不清，反之亦然。我们的发现还表明，当z-轴DM相互作用增加时，纠缠会上升。此外，通过设置自旋的强度耦合，我们迅速恢复了各向同性XY和XXX Heisenberg模型。最后，鲱鱼闪光耦合会影响纠缠程度。实际上，当鲱鱼闪光耦合和温度在较小的值时，纠缠程度为最高。尽管如此，当鲱鱼闪光耦合处于实质性值时，纠缠程度趋于稳定。
In this study, we use the concept of $l_1$-norm coherence to characterize the entanglement of a two--qutrit Heisenberg XXZ model for subject to a uniform magnetic field and z--axis Dzyaloshinskii--Moriya interaction with Herring-Flicker coupling. We show the temperature, magnetic field, DM interaction, and distance of Herring-Flicker coupling all can control the entanglement. However, the state system becomes less entangled at high temperatures or strong magnetic fields and vice versa. Our findings also suggest that entanglement rises when the z--axis DM interaction increases. Moreover, by setting the strengths coupling of the spin, we quickly recover the isotropic XY and XXX Heisenberg models. Finally, Herring-Flicker coupling affects the degree of entanglement. In fact, when Herring-Flicker coupling and temperature are at small values, the degree of entanglement is at its highest. Still, when Herring-Flicker coupling is at substantial values, the degree of entanglement tends to stabilize.
