论文摘要
该小组最近在Sherbrooke中做出的猜想是，他们观察到的在库酸盐中伪间隙相的异常热室效应是由于声子引起的，这是基于早期结果支持的，即在此阶段观察到的循环循环顺序必须在此阶段诱导晶格扭曲，这在顺序参数和应用磁性磁场中是线性的。晶体的降低对称性取决于场的方向。结果是，弹性常数改变与田地成正比，并显示出与与洛伦兹力相同的对称性的轴向热传输，以实现正常的电子霍尔效应。建议对磁场中的弹性常数进行直接测量，以验证结果的定量方面。
The conjecture made recently by the group at Sherbrooke, that their observed anomalous thermal Hall effect in the pseudo-gap phase in the cuprates is due to phonons, is supported on the basis of an earlier result that the observed loop-current order in this phase must induce lattice distortions which are linear in the order parameter and an applied magnetic field. The lowered symmetry of the crystal depends on the direction of the field. A consequence is that the elastic constants change proportional to the field and are shown to induce axial thermal transport with the same symmetries as the Lorentz force enforces for the normal electronic Hall effect. Direct measurements of elastic constants in a magnetic field are suggested to verify the quantitative aspects of the results.
