Lateral spin-orbit interaction and spin polarization in quantum point contacts
Anh T. Ngo, P. Debray, Sergio Ulloa
We study ballistic transport through semiconductor quantum point contact systems under different confinement geometries and applied fields. In particular, we investigate how the {\…
Many-body electronic structure and Kondo properties of cobalt-porphyrin molecules
Luis G. G. V. Dias da Silva, Murilo L. Tiago, Sergio E. Ulloa +2
We use a combination of first principles many-body methods and the numerical renormalization-group technique to study the Kondo regime of cobalt-porphyrin compounds adsorbed on a C…
Tunable pseudogap Kondo effect and quantum phase transitions in Aharonov-Bohm interferometers
Luis G. G. V. Dias da Silva, Nancy Sandler, Pascal Simon +2
We study two quantum dots embedded in the arms of an Aharonov-Bohm ring threaded by a magnetic flux. The system can be described by an effective one-impurity Anderson model with an…
