Recent years have seen tremendous progress in the theoretical understanding of quantum
systems driven dissipatively by coupling to different baths at their edges. This was possible …

In the early 1970s, Wilson developed the concept of a fully nonperturbative renormalization
group transformation. When applied to the Kondo problem, this numerical renormalization …

The present knowledge of QCD confining forces between static test charges is summarised,
with an emphasis on lattice results. Recent developments in relating QCD potentials to …

We observe a strong Kondo effect in a semiconductor quantum dot when a small magnetic
field is applied. The Coulomb blockade for electron tunneling is overcome completely by the …

Abstract We study the Fano-Kondo effect in a closed Aharonov-Bohm (AB) interferometer
which contains a single-level quantum dot and predict a frequency doubling of the AB …

Electronic transport through a quantum dot strongly coupled to electrodes is studied within a
model with two conduction channels. It is shown that multiple scattering and interference of …

We measured the phase evolution of electrons as they traverse a quantum dot (QD) formed
in a two-dimensional electron gas that serves as a localized spin. The traversal phase …

We suggest a simple system of two electron droplets which should display two-channel
Kondo behavior at experimentally accessible temperatures. Stabilization of the two-channel …

We study electron transport through a closed Aharonov-Bohm interferometer containing two
noninteracting single-level quantum dots. The quantum-dot levels are coupled to each other …

We use the Matsubara functional renormalization group (FRG) to describe electronic
correlations within the single impurity Anderson model. In contrast to standard FRG …
