Fundamental Time Constant for a Biased Quantum Dot in the Kondo Regime
arXiv:cond-mat/0108525
Abstract
It is shown that the rate limiting time constant for the formation of the Kondo state in a quantum dot can be extracted analytically from known perturbation theoretic results. The prediction obtained is verified via numerical simulations in the noncrossing approximation.
