Critical temperature and Ginzburg region near a quantum critical point in two-dimensional metals
J. Bauer, P. Jakubczyk, W. Metzner
We compute the transition temperature and the Ginzburg temperature above near a quantum critical point at the boundary of an ordered phase with a broken dis…
Finite temperature crossovers near quantum tricritical points in metals
P. Jakubczyk, J. Bauer, W. Metzner
We present a renormalization group treatment of quantum tricriticality in metals. Applying a set of flow equations derived within the functional renormalization group framework we…
Boundary effects on one-particle spectra of Luttinger liquids
K. Schoenhammer, V. Meden, W. Metzner +2
We calculate one-particle spectra for a variety of models of Luttinger liquids with open boundary conditions. For the repulsive Hubbard model the spectral weight close to the bound…
Two particle correlations and orthogonality catastrophe in interacting Fermi systems
W. Metzner, C. Castellani
The wave function of two fermions, repulsively interacting in the presence of a Fermi sea, is evaluated in detail. We consider large but finite systems in order to obtain an unabig…
