论文摘要
互惠空间中手性多胎费的手性与真实空间中晶体晶格结构的手性有关。在这项工作中，我们提出了一种策略，以通过二阶光学传输方式在非磁系统中检测和识别非磁性系统中的相反性多胎。手性晶体是通过反转操作相关的，不能通过任何实验操作彼此重叠，并且给定的K点晶体中的手性多fermions the cryster toss Host host host host hoss to soste。手性的变化通过手性费米子主导的二阶电荷电流的符号变化表示。该策略可通过利用大量运输来研究互惠和真实空间中的手势之间的关系。
The chirality of chiral multifold fermions in reciprocal space is related to the chirality of the crystal lattice structure in real space. In this work, we propose a strategy to detect and identify opposite-chirality multifold fermions in nonmagnetic systems by means of second-order optical transports. The chiral crystals are related by an inversion operation and cannot overlap with each other by any experimental operation, and the chiral multifold fermions in the crystals host opposite chiralities for a given k-point. A change of chirality is indicated by a sign change of the second-order charge current dominated by chiral fermions. This strategy is effective to study the relationship between chiralities in reciprocal and real spaces by utilizing bulk transport.
