Quantum phase transition in quantum dot trimers

We investigate a system of three tunnel-coupled semiconductor quantum dots in a triangular geometry, one of which is connected to a metallic lead, in the regime where each dot is essentially singly occupied. Both ferromagnetic and antiferromagnetic spin- 1 2 Kondo regimes, separated by a quantum pha...
