论文摘要
螺旋自旋液体是在许多沮丧的自旋系统中发生的独特经典旋转液体，但不包括新的物质阶段。由于广泛的经典地基型退化性，螺旋旋转液体中的旋转会从低温下的螺旋构型收集的集合进行热波动。这些螺旋传播波传动在相互空间中形成连续的歧管，\ textit {i.e。}，螺旋轮廓或螺旋表面，强烈控制低温的热波动和磁性物理。在本文中，系统探索了传达螺旋旋转液体物理的相关自旋模型，并在模型构造中阐明了螺旋流形的几何起源。进一步阐明了基于螺旋歧管的尺寸和编成的螺旋旋转液体。对于每个类别，对物理特性进行了一般和特定示例研究。结果与各种沮丧的磁铁有关。对材料进行了调查，并提出了未来的实验。
Spiral spin liquids are unique classical spin liquids that occur in many frustrated spin systems, but do not comprise a new phase of matter. Owing to extensive classical ground-state degeneracy, the spins in a spiral spin liquid thermally fluctuate cooperatively from a collection of spiral configurations at low temperatures. These spiral propagation wavevectors form a continuous manifold in reciprocal space, \textit{i.e.}, a spiral contour or a spiral surface, that strongly governs the low-temperature thermal fluctuations and magnetic physics. In this paper, the relevant spin models conveying the spiral spin liquid physics are systematically explored and the geometric origin of the spiral manifold is clarified in the model construction. The spiral spin liquids based on the dimension and the codimension of the spiral manifold are further clarified. For each class, the physical properties are studied both generally and for specific examples. The results are relevant to a wide range of frustrated magnets. A survey of materials is given and future experiments are suggested.
