Seminar on 'Non-Fermi-liquid Kondo screening under Rabi driving', by Moshe Goldstein

Event ended

On September 11 a seminar on 'Non-Fermi-liquid Kondo screening under Rabi driving' by Moshe Goldstein (Tel Aviv University) will be held.

Abstract:
We investigate a Rabi-Kondo model describing an optically driven two-channel quantum dot device featuring a non-Fermi liquid Kondo effect. Optically induced Rabi oscillation between the valence and conduction levels of the dot give rise to a two-stage Kondo effect: Primary screening of the local spin is followed by secondary nonequilibrium screening of the local orbital degree of freedom. Using bosonization arguments and the numerical renormalization group, we compute the dot emission spectrum and residual entropy. Remarkably, both exhibit two-stage Kondo screening with non-Fermi-liquid properties at both stages.
