Symmetry quantum correlations and their properties have been explored extensively in the solid spin-chain model previously. However, the asymmetric correlations, e.g. quantum steering, have attracted less attention in this context. In this work, we study quantum steering, based on the entropy uncertainty relation as a measure, in the XXZ Heisenberg model with an inhomogeneous magnetic field. The asymmetry feature of quantum steering is focused and analyzed in detail. The results show that inhomogeneous magnetic fields can always induce asymmetry steering. Meanwhile, quantum steering is suppressed with an increasing external magnetic field B or temperature T. Furthermore, we show that quantum steering is enhanced with an increasing anisotropy J _z while the asymmetry character disappears at the same time.

先前在固体自旋链模型中已经广泛探索了对称量子相关性及其性质。然而，在这种情况下，非对称相关性（例如量子转向）引起的关注较少。在这项工作中，我们在具有非均匀磁场的 XXZ 海森堡模型中研究了基于熵不确定性关系作为度量的量子转向。重点关注并详细分析了量子转向的不对称特征。结果表明，不均匀的磁场总是会引起不对称转向。同时，随着外部磁场B或温度T的增加，量子转向受到抑制。此外，我们表明量子转向随着各向异性J _z的增加而增强 而不对称特征同时消失。
