论文摘要
尽管从理论上讲，尽管明显的无处不在和各种量子自旋液体，但对旋转液体的实验确认仍然是一个巨大的挑战。由于最近在一系列候选材料中旋转液体的证据激增的动机，我们强调了实验方案，涉及热厅的传输和光谱测量，这可能会导致旋转液体的吸烟枪标志超出常规液体。为了清楚起见，我们研究了方格旋转液体，理论上预测了可能在相应的旋转液体候选物中出现的现象。这些特征的机制可以追溯到旋转液体的固有特征或外部野外驱动的行为。我们的结论不取决于晶格的几何形状，并且可以广泛应用于其他相关的自旋液体。
Despite the apparent ubiquity and variety of quantum spin liquids in theory, experimental confirmation of spin liquids remains to be a huge challenge. Motivated by the recent surge of evidences for spin liquids in a series of candidate materials, we highlight the experimental schemes, involving the thermal Hall transport and spectrum measurements, that can result in smoking-gun signatures of spin liquids beyond the usual ones. For clarity, we investigate the square lattice spin liquids and theoretically predict the possible phenomena that may emerge in the corresponding spin liquids candidates. The mechanisms for these signatures can be traced back to either the intrinsic characters of spin liquids or the external field-driven behaviors. Our conclusion does not depend on the geometry of lattices and can broadly apply to other relevant spin liquids.
