Kondo effect in single atom contacts: the importance of the atomic geometry
Lucia Vitali, Robin Ohmann, Sebastian Stepanow +6
Co single atom junctions on copper surfaces are studied by scanning tunneling microscopy and ab-initio calculations. The Kondo temperature of single cobalt atoms on the Cu(111) sur…
Hopf algebras and the logarithm of the S-transform in free probability
Mitja Mastnak, Alexandru Nica
Let k be a positive integer and let G_k denote the set of non-commutative k-variable distributions μsuch that μ(X_1) = ... = μ(X_k) = 1. G_k is a group under the operation of free…
Effect of quantum confinement of surface electrons on an atomic motion on nanoislands
A. S. Smirnov, N. N. Negulyaev, L. Niebergall +3
Ab initio calculations and kinetic Monte Carlo simulations demonstrate that the quantum confinement of surface electrons to nanoislands can significantly affect the growth process…
Tailoring exchange interactions in engineered nanostructures: Ab initio study
O. O. Brovko, P. A. Ignatiev, V. S. Stepanyuk +1
We present a novel approach to spin manipulation in atomic-scale nanostructures. Our ab initio calculations clearly demonstrate that it is possible to tune magnetic properties of s…
