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

We review two important non-perturbative approaches for extracting the physics of low-
dimensional strongly correlated quantum systems. Firstly, we start by providing a …

We review the recent progress in theory and experiments with lateral triple quantum dots
with controlled electron numbers down to one electron in each dot. The theory covers …

We propose to use residual anyons of the overscreened Kondo effect for topological
quantum computation. A superconducting proximity gap of Δ< TK can be utilized to isolate …

We analyze theoretically and experimentally the electronic structure and charging diagram
of three coupled lateral quantum dots filled with electrons. Using the Hubbard model and …

The role of discrete orbital symmetry in mesoscopic physics is manifested in a system
consisting of three identical quantum dots forming an equilateral triangle. Under a …

We review here some universal aspects of the physics of two-electron molecular transistors
in the absence of strong spin–orbit effects. Several recent quantum dot experiments have …

The multichannel Kondo model supports effective anyons on the partially screened impurity,
as suggested by its fractional impurity entropy. It was recently demonstrated for the multi …

The spatial length of the Kondo screening is still a controversial issue related to Kondo
physics. While renormalization-group and Bethe-Ansatz solutions have provided detailed …

We study theoretically a triangular cluster of three magnetic impurities, hybridizing locally
with conduction electrons of a metallic host. Such a cluster is the simplest to exhibit …
