Zero-Field Kondo Splitting and Quantum-Critical Transition in Double Quantum Dots
Zero-Field Kondo Splitting and Quantum-Critical Transition in Double Quantum Dots
Double quantum dots offer unique possibilities for the study of many-body correlations. A system containing one Kondo dot and one effectively noninteracting dot maps onto a single-impurity Anderson model with a structured (nonconstant) density of states. Numerical renormalization-group calculations show that, while band filtering through the resonant dot splits the …
