URu $_2$ Si $_2$中旋序的符号：Landau-Ginzburg序理论
Signatures of spinorial order in URu$_2$Si$_2$: Landau-Ginzburg theory of hastatic order
摘要：
URu $_2$ Si $_2$中隐藏的顺序在30多年后仍然是一个令人信服的谜，序参量仍然没有被确定。一个有趣的相的建议是hastatic秩序：一个对称性打破重费米液体与自旋杂化打破单和双时间反演对称。Hastatic顺序是材料中的第一个旋序，而不是矢量顺序，但以前的工作尚未发现旋序性质的直接后果。在本文中，我们重新审视了朗道-金兹伯格理论中的hastatic建议。而不是一个单一的spinorial序参量打破双时间反演对称性，我们发现两个规范不变的矢量订单：预期的复合订单与现场的时刻，和一个新的数量捕捉对称性打破单独的spinorial性质。讨论了涨落和无序对四元对称性破缺的影响，解释了URu $_2$ Si $_2$中面内磁矩的缺失，并预言了一个新的横场跃迁.
英文摘要：
The hidden order in URu$_2$Si$_2$ remains a compelling mystery after more than thirty years, with the order parameter still unidentified. One intriguing proposal for the phase has been hastatic order: a symmetry breaking heavy Fermi liquid with a spinorial hybridization that breaks both single and double time-reversal symmetry. Hastatic order is the first spinorial, rather than vectorial order in materials, but previous work has not yet found direct consequences of the spinorial nature. In this paper, we revisit the hastatic proposal within Landau-Ginzburg theory. Rather than a single spinorial order parameter breaking double-time-reversal symmetry, we find two gauge invariant vectorial orders: the expected composite order with on-site moments, and a new quantity capturing symmetries broken solely by the spinorial nature. We address the effect of fluctuations and disorder on the tetragonal symmetry breaking, explaining the absence of in-plane moments in URu$_2$Si$_2$ and predicting a new transition in transverse field.
