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 integer quantised conductance of one-dimensional electron systems is a well-
understood effect of quantum confinement. A number of fractionally quantised plateaus are …

We study the zero-bias conductance through the system of two quantum dots, one of which
is embedded directly between the source and drain electrodes, while the second dot is side …

Low-temperature three-terminal transport measurements through a thiol end-capped π-
conjugated molecule have been carried out. Electronic excitations, including zero and finite …

Spectroscopic measurements with low-temperature scanning tunneling microscopes have
been used very successfully for studying not only individual atomic or molecular spins on …

We have studied the Kondo effect of a spin-1/2 impurity coupled to a two-dimensional
altermagnet host material. To attain the low-temperature many-body Kondo physics of the …

The thermal dependence of the zero-bias conductance for the single electron transistor is
the target of two independent renormalization-group approaches, both based on the spin …

Quantum impurities exhibit fascinating many-body phenomena when the small interacting
impurity changes the physics of a large noninteracting environment. The characterisation of …

Majorana zero modes (MZMs) emerging at the edges of topological superconducting wires
have been proposed as the building blocks of novel, fault-tolerant quantum computation …

We study the low-temperature transport properties of systems of parallel quantum dots
described by the N-impurity Anderson model. We calculate the quasiparticle scattering …
