在任意强度的散射势下，发现了存在单个散射体的弱相互作用电子气的电导。在弱相互作用下，可以使用简单的重整化群方法来代替标准的玻色子化过程。我们的技术使我们能够考虑到电子的背散射，导致低温电导从典型的Luttinger液体的行为的偏差。在磁场存在的情况下，背散射可能会导致在偏置等于塞曼能量的微分电导的峰值。
The conductance of a weakly interacting electron gas in the presence of a single scatterer is found at arbitrary strength of the scattering potential. At weak interaction, a simple renormalization group approach can be used instead of the standard bosonization procedure. Our technique allows us to take into account the backscattering of electrons that leads to deviations of the low-temperature conductance from the behavior typical for Luttinger liquid. In the presence of magnetic field, the backscattering may give rise to a peak in differential conductance at bias equal to the Zeeman energy.
