Abstract

Lu this paper we discuss two issues important to high frequency quantum transport in ultrasmall systems. First, we discuss the question of the intrinsic high frequency cutoff in quantum systems and show that neither the traversal time proposed by Büttiker and Landauer nor the scattering time proposed by Wigner is adequate. This is confirmed in a model for a resonant tunneling device. We also consider the effect of charging, the role of 1W time constant, and point out the connection between this and the X-ray edge problem. Second, we study the connection between AC quantum transport and quantum chaos, and present some numerical results.
