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…
Nonequilibrium theory of scanning tunneling spectroscopy via adsorbate resonances: nonmagnetic and Kondo impurities
M. Plihal, J. W. Gadzuk
We report on a fully nonequilibrium theory of the scanning tunneling microscopy (STM) through resonances induced by impurity atoms adsorbed on metal surfaces. The theory takes into…
Kondo time scales for quantum dots - response to pulsed bias potentials
Martin Plihal, David C. Langreth, Peter Nordlander
The response of a quantum dot in the Kondo regime to rectangular pulsed bias potentials of various strengths and durations is studied theoretically. It is found that the rise time…
