摘要: In a recent letter, Yi et al. PRL 78, 3523 (1997), have considered the stability of Charge Density Wave in one-dimensional ring, presence an Aharonov-Bohm flux. This comment shows that, one dimension, depends on parity number electrons ring. effect is similar to known for persistent current rings.
