我们考虑了一维介观环中的非相互作用电子，并研究了由于电子-声子相互作用而产生的弱扰动势的响应。研究发现，穿线通量往往会抑制Peierls不稳定性，从而导致在调节通量时发生Peierls相变的可能性。文中还讨论了对持续电流的相应影响。
We consider noninteracting electrons confined to a one-dimensional mesoscopic ring with a magnetic flux threading its center, and investigate the response to a weak perturbing potential due to the electron-phonon interaction. It is found that the threading flux tends to suppress the Peierls instability, leading to the possibility of a Peierls transition as the flux is adjusted. The corresponding effects on the persistent current are also discussed.
