论文摘要
由最近的实验动机[J. H. Han等。 al。，物理。 Rev. Lett.122，065303（2019）]，我们使用最先进的密度 - 矩阵rentrix Renoralization-Group数值方法研究了合成霍尔管中相互作用的fermions的多体物理学。由于该合成大厅管的腿间耦合产生了有趣的自旋调整式Zeeman场，因此出现了外来的拓扑和磁性特性。尤其是，通过计算3个旋转熵，纠缠熵，能量隙，和3个自旋磁极磁极的局部磁性，可以预测四个新的新量子相，例如非血管学旋转载体和 - 量子传感器磁磁性绝缘体，以及拓扑和非解体旋转混合的磁管绝缘子。此外，还揭示了由相互作用以及腿部耦合引起的拓扑磁相变。我们的结果铺平了一种探索由螺旋旋转载体和-Tensor Zeeman田地引起的多体（拓扑）状态的新方法。
Motivated by a recent experiment [J. H. Han, et. al., Phys. Rev. Lett.122, 065303 (2019)], we investigate many-body physics of interacting fermions in a synthetic Hall tube, using state-of-the-art density-matrix renormalization-group numerical method. Since the inter-leg couplings of this synthetic Hall tube generate an interesting spin-tensor Zeeman field, exotic topological and magnetic properties occur. Especially, four new quantum phases, such as nontopological spin-vector and -tensor paramagnetic insulators, and topological and nontopological spin-mixed paramagnetic insulators, are predicted by calculating entanglement spectrum, entanglement entropies, energy gaps, and local magnetic orders with 3 spin-vectors and 5 spin-tensors. Moreover, the topologically magnetic phase transitions induced by the interaction as well as the inter-leg couplings are also revealed. Our results pave a new way to explore many-body (topological) states induced by both the spiral spin-vector and -tensor Zeeman fields.
