对J. Ishioka等人“通过手征电荷密度波中的Friedel振荡观察到的电荷宇称对称性”一文的评论
Comment on "Charge-parity symmetry observed through Friedel oscillations in chiral charge-density waves" by J. Ishioka et al
摘要：
在他们的出版物[Phys. Rev B，84，245125（2011）]中，Ishioka等人根据参数H_CDW讨论了最近发现的1 T-TiSe 2中的手性电荷密度波态，其符号被认为对应于手性序的手性。在这里，我们指出，H_CDW，由Ishioka等人定义，不能用这种方式来表征手性。一种替代措施的手性为1 T-TiSe 2的特定情况下，建议。
英文摘要：
In their publication [Phys. Rev B, 84, 245125 (2011)], Ishioka et al. discuss the recently discovered chiral charge density wave state in 1T-TiSe2 in terms of a parameter H_CDW, whose sign is suggested to correspond to the handedness of the chiral order. Here we point out that H_CDW, as defined by Ishioka et al., cannot be used to characterize chirality in that way. An alternative measure of chirality for the specific case of 1T-TiSe2 is suggested.
