论文摘要
我们介绍了一类非热式系统，这些系统会破坏电磁互惠，同时保留时间反转对称性，并描述其新型的极化动力学。我们表明，可以使用涉及过渡金属二色元（TMDS）的范德华异质结构来实现这类系统。我们的工作为使用紧凑型，大面积和无磁体结构实现强光学非进取心和偏振方向扩增提供了途径。
We introduce a class of non-Hermitian systems that break electromagnetic reciprocity while preserving time-reversal symmetry, and describe its novel polarization dynamics. We show that this class of systems can be realized using van der Waals heterostructures involving transition-metal dichalcogenides (TMDs). Our work provides a path towards achieving strong optical nonreciprocity and polarization-dependent directional amplification using compact, large-area and magnet-free structures.
