一维环Aharonov－Bohm势对极化子的影响

Effect of Aharonov Bohm Potential on the Polaron in 1D Ring

讨论Ａｈａｒｏｎｏｖ－Ｂｏｈｍ势对极化子的影响，证明了虽然有势无场，对电子不产生直接的动力学作用，但磁通仍然影响极化子的峰高、宽度、迁移速度和晶格形变能．

The effect of Aharonov-Bohm potential on polaron in 1D ring is discussed. The results show that the parameters of soliton-type polaron, such as the height and width of wave-packet, the travelling velocity and the total energy, depend on the magnetic flux.
