摘要：

We calculate the temperature dependence of the inelastic scattering rate at the mobility edge in a disordered system in which diffusion is characterized by a wavevector and frequency dependence, and compare it with that obtained when only conventional diffusion occurs. We find that the inelastic scattering rate exhibits a linear temperature dependence in both cases. We discuss this result in the context of low-temperature transport measurements in integral quantum Hall samples, and point out certain theoretical inconsistencies which need to be resolved.
