Selective tuning of spin-orbital Kondo contributions in parallel-coupled quantum dots
Selective tuning of spin-orbital Kondo contributions in parallel-coupled quantum dots
We use cotunneling spectroscopy to investigate spin, orbital, and spin-orbital Kondo transport in a strongly confined system of InAs double quantum dots that are parallel coupled to source and drain. In the one-electron transport regime, the higher-symmetry spin-orbital Kondo effect manifests at orbital degeneracy and no external magnetic field. We …
