摘要
The response of the Luttinger liquid to a local potential is studied at zero temperature. It exhibits a crossover behavior. On the largest time scale and in the case of repulsive electron-electron interaction, the backscattering from the potential contributes to the core-hole Green's function G(t) the factor (t0/t)1/8-a universal (potential independent) decay law. The orthogonality catastrophe remains of the same analytical type as for the simple metals.
