Many-body electronic structure and Kondo properties of cobalt-porphyrin molecules
Many-body electronic structure and Kondo properties of cobalt-porphyrin molecules
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 Cu(111) surface. We find the Kondo temperature to be highly sensitive to both molecule charging and distance to the surface, which can explain the variations observed …
