摘要: 研究低温下准一维电子气的两体背向散射的磁效应。计入电子-电子背向散射,采用Coleman玻色化方法实现电荷-自旋分离,得到了自旋波激发谱;定义磁化强度算符,利用线性响应理论得出磁化率的严格解,讨论两体背向散射对磁化率的影响。Abstract: We investigate the magnetic effects of electron lelectron backscattering for lower temperature,We make the separation of charge spin and define the magnetization using Coleman's bosonization.The spin susceptibility is known based on the linear response theory,the spin excitation spectrum is gotten under the consideration of electron electron backscattering.and the effects of backscattering to susceptibility is discussed.
