Response to Anderson

ac response in the nonequilibrium Anderson impurity model.

The ac response of a single Anderson impurity coupled to two reservoirs with different chemical potentials is studied using an equation of motion approach. In the Kondo regime, we show that resonant behavior in the ac response is found in the low-frequency limit and the frequency of the ac field matches the chemical potential differences. The resonant behavior is a direct consequence of the “do...

Re-localization due to finite response times in a nonlinear Anderson chain

We study a disordered nonlinear Schrödinger equation with an additional relaxation process having a finite response time τ . Without the relaxation term, τ = 0, this model has been widely studied in the past and numerical simulations showed subdiffusive spreading of initially localized excitations. However, recently Caetano et al. [Eur. Phys. J. B 80, 321 (2011)] found that by introducing a res...
