Generalized conductance sum rule in atomic break junctions
S. Kirchner, J. Kroha, E. Scheer
When an atomic-size break junction is mechanically stretched, the total conductance of the contact remains approximately constant over a wide range of elongations, although at the…

Diagrammatic theory of the Anderson impurity model with finite Coulomb interaction
K. Haule, S. Kirchner, J. Kroha +1
We have developed a self-consistent conserving pseudo particle approximation for the Anderson impurity model with finite Coulomb interaction, derivable from a Luttinger Ward functi…
