摘要

本文基于夏尔马-米塔尔量子不和及其极限情况，研究了海森堡 XYZ 模型中具有 Dzyaloshinskii-Moriya 相互作用的量子相关性。研究结果表明，夏尔马-米塔尔量子不和是一个忠实的量子，而且 Dzyaloshinskii-Moriya 相互作用显著增强了双元系统内的量子相关性。与此相反，温度的影响恰恰相反，它导致系统中量子相关性数量的减少。

Nonclassical Correlations Via Sharma–Mittal Quantum Discord in Heisenberg XYZ Model With Dzyaloshinskii–Moriya Interaction

In this paper, we study quantum correlations in a Heisenberg XYZ model with the Dzyaloshinskii–Moriya interaction based on the Sharma–Mittal quantum discord and its limiting cases. The results obtained show that the Sharma–Mittal quantum discord is a faithful quantifier and that the Dzyaloshinskii–Moriya interaction significantly enhances quantum correlations within the bipartite system. In contrast, temperature has the opposite effect, leading to a reduction in the quantity of quantum correlations in the system.
