Scaling of the conductance in a quantum wire
V. Meden, S. Andergassen, W. Metzner +2
The conductance G of an interacting nano-wire containing an impurity and coupled to non-interacting semi-infinite leads is studied using a functional renormalization group method.…

Soft Fermi Surfaces and Breakdown of Fermi Liquid Behavior
W. Metzner, D. Rohe, S. Andergassen
Electron-electron interactions can induce Fermi surface deformations which break the point-group symmetry of the lattice structure of the system. In the vicinity of such a "Pomeran…
