Advances in high-resolution and spin-resolved scanning tunnelling microscopy, as well as
atomic-scale manipulation, have enabled the bottom-up, atom-by-atom creation and …

We review the problem of spin decoherence of magnetic atoms deposited on a surface.
Recent breakthroughs in scanning tunnelling microscopy (STM) make it possible to probe …

In recent years inelastic spin-flip spectroscopy using a low-temperature scanning tunneling
microscope has been a very successful tool for studying not only individual spins but also …

The ability to manipulate single atoms has opened up the door to constructing interesting
and useful quantum structures from the ground up. On the one hand, nanoscale …

Mutually interacting magnetic atoms coupled to a superconductor have gained enormous
interest due to their potential for the realization of topological superconductivity. Individual …

Two-impurity Kondo models are paradigmatic for correlated spin-fermion systems. Working
with Mn atoms on Au (111) covered by a monolayer of MoS 2, we tune the interadatom …

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

We explore the physics of a spin-1/2 Heisenberg chain with Kondo interaction, J k, to a two-
dimensional electron gas. At weak J k the problem maps onto a Heisenberg chain locally …

Using double quantum dots as the weak link of a Josephson junction, we realize the
superconducting analog of the celebrated two-impurity Kondo model. The device shows a …

Investigation of intermolecular electron spin interaction is of fundamental importance in both
science and technology. Here, radical pairs of all-trans retinoic acid molecules on Au (111) …
