Suppression of Kondo effect in a quantum dot by external irradiation
A. Kaminski, Yu.V. Nazarov, L.I. Glazman
TL;DR
This paper shows that external irradiation induces decoherence in a quantum dot, suppressing the Kondo effect in conductance even at zero temperature, with conductance depending on irradiation power.
Contribution
It provides a detailed analysis of how external irradiation causes decoherence and suppresses the Kondo effect in quantum dots, which was not previously characterized.
Findings
Decoherence from irradiation cuts off the Kondo anomaly.
Conductance depends on irradiation power.
Kondo effect can be suppressed at zero temperature.
Abstract
We demonstrate that the external irradiation brings decoherence in the spin states of the quantum dot. This effect cuts off the Kondo anomaly in conductance even at zero temperature. We evaluate the dependence of the DC conductance in the Kondo regime on the power of irradiation, this dependence being determined by the decoherence.
