The Susceptibility of a Quantum Wire with the Electron Electron Backscattering

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.
