A revolution in electronics is in view, with the contemporary evolution of the two novel
disciplines of spintronics and molecular electronics. A fundamental link between these two …

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

In the Kondo effect, a localized magnetic moment is screened by forming a correlated
electron system with the surrounding conduction electrons of a non-magnetic host. Spin S …

The future of nanoscale spin-based technologies hinges on a fundamental understanding
and dynamic control of atomic-scale magnets. The role of the substrate conduction electrons …

An important class of approaches to the description of electronic transport through
molecules and quantum dots is based on the master equation. We discuss various …

We have measured quantum transport through an individual Fe4 single-molecule magnet
embedded in a three-terminal device geometry. The characteristic zero-field splittings of …

We study the triangular antiferromagnet Cu 3 in external electric fields, using symmetry
group arguments and a Hubbard model approach. We identify a spin-electric coupling …

At present, metal–molecular tunnel junctions are recognized as important active elements in
molecular electronics. This gives a strong motivation to explore physical mechanisms …

The properties of quantum systems interacting with their environment, commonly called
open quantum systems, can be affected strongly by this interaction. Although this can lead to …

Single-molecule spintronics investigates electron transport through magnetic molecules that
have an internal spin degree of freedom. To understand and control these individual …
