Transient currents and universal timescales for a fully time-dependent quantum dot in the Kondo regime
Martin Plihal, David C. Langreth, Peter Nordlander
Using the time-dependent non-crossing approximation, we calculate the transient response of the current through a quantum dot subject to a finite bias when the dot level is moved s…

Fundamental Time Constant for a Biased Quantum Dot in the Kondo Regime
Martin Plihal, David C. Langreth, Peter Nordlander
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…
