Using remarkably simple experimental techniques it is possible to gently break a metallic
contact and thus form conducting nanowires. During the last stages of the pulling a neck …

An introductory survey of the theoretical ideas and calculations and the experimental results
which depart from Landau Fermi liquids is presented. The common themes and possible …

The ordinary single-channel Kondo model consists of one or more spin-½ local moments
interacting antiferromagnetically with conduction electrons in a metal. This model has …

Some of the most intriguing problems in solid-state physics arise when the motion of one
electron dramatically affects the motion of surrounding electrons. Traditionally, such highly …

We study resonant tunneling through a single-level quantum dot in the presence of strong
Coulomb repulsion beyond the perturbative regime. The level is either spin degenerate or …

Many-body correlations and macroscopic quantum behaviours are fascinating condensed
matter problems. A powerful test-bed for the many-body concepts and methods is the Kondo …

Recently, a new approach, based on boundary conformal field theory, has been applied to a
variety of quantum impurity problems in condensed matter and particle physics. A …

Our present understanding of how the interactions between electrons affect the metallic state
has, for forty years, rested on the foundations of Landau's Fermi-liquid theory. It provides the …

We study resonant tunneling through a quantum dot with one degenerate level in the
presence of strong Coulomb repulsion and a bosonic environment. Using a real-time …

Molecular electronic devices currently serve as a platform for studying a variety of physical
phenomena only accessible at the nanometer scale. One such phenomenon is the highly …
