Anomalous quasiparticles in the zone center electron pocket of the kagomé ferromagnet Fe3Sn2
Sandy Adhitia Ekahana, Y. Soh, Anna Tamai +14
One material containing kagome bilayers and featuring both exceptional magnetism and electron transport is the ferromagnetic metal Fe3Sn2. Notwithstanding the widespread interest i…
The Kondo effect in ferromagnetic atomic contacts
M. R. Calvo, J. Fernández-Rossier, J. J. Palacios +3
Iron, cobalt and nickel are archetypal ferromagnetic metals. In bulk, electronic conduction in these materials takes place mainly through the and electrons, whereas the mag…
A Novel Approach to Study Highly Correlated Nanostructures: The Logarithmic Discretization Embedded Cluster Approximation
E. V. Anda, G. Chiappe, C. A. Busser +4
This work proposes a new approach to study transport properties of highly correlated local structures. The method, dubbed the Logarithmic Discretization Embedded Cluster Approximat…
Hidden multiferroic order in graphene zigzag ribbons
J. Fernández-Rossier
The insulating magnetic phase in graphene zigzag ribbons, predicted both by density functional and mean field Hubbard model calculations, is described without additional approximat…
VO: A Strongly Correlated Metal Close to a Mott- Hubbard Transition
F. Rivadulla, J. Fernandez-Rossier, M. Garcia-Hernandez +3
Here we present experimental and computational evidences to support that rock-salt cubic VO is a strongly correlated metal with Non-Fermi-Liquid thermodynamics and an unusually str…
Transport through quantum dots: A combined DMRG and cluster-embedding study
F. Heidrich-Meisner, G. B. Martins, C. A. Busser +5
The numerical analysis of strongly interacting nanostructures requires powerful techniques. Recently developed methods, such as the time-dependent density matrix renormalization gr…
