Hybrid quantum dot structures are potential building blocks for spintronic devices and
quantum logic gates, within which the understanding of many-body correlations is a …

The interplay between the coupling of an interacting quantum dot to a conduction band and
its connection to localized levels has been studied in a triple quantum-dot arrangement. The …

For a double quantum dot system in a parallel geometry, we demonstrate that by combining
the effects of a flux and driving an electrical current through the structure, the spin …

We study a Kondo state that is strongly influenced by its proximity to an ω− 1/2 singularity in
the metallic host density of states. This singularity occurs at the bottom of the band of a one …

We study tunneling through a resonant level connected to two dissipative bosonic baths:
one is the resistive environment of the source and drain leads, while the second comes from …

We demonstrate delicate control over the Kondo effect and its interplay with quantum
interference in an Aharonov-Bohm interferometer containing one Kondo dot and one …

We show that conservation laws in quantum mechanics naturally lead to metric spaces for
the set of related physical quantities. All such metric spaces have an “onion-shell” geometry …

We examine the quality of the local self-energy approximation, applied here to models of
multiple quantum impurities coupled to an electronic bath. The local self-energy is obtained …

We study a pseudogap Anderson-Holstein model of a magnetic impurity level that hybridizes
with a conduction band whose density of states vanishes in power-law fashion at the Fermi …

We propose a numerical method to simulate a transport experiment using a quantum dot
interferometer made of two quantum wires in parallel [S. Takada et al., Phys. Rev. Lett. 113 …
