Charge density wave in the spin ladder of SrCaCuO

Krzysztof Wohlfeld, Andrzej M. Oles, George A. Sawatzky

We consider a multiband charge transfer model for a single spin ladder describing the holes in SrCaCuO. Using Hartree-Fock approximation we show how the…

A gentle introduction to the functional renormalization group: the Kondo effect in quantum dots

Sabine Andergassen, Tilman Enss, Christoph Karrasch +1

The functional renormalization group provides an efficient description of the interplay and competition of correlations on different energy scales in interacting Fermi systems. An…

Electrical resistivity near Pomeranchuk instability in two dimensions

Luca Dell'Anna, Walter Metzner

We analyze the DC charge transport in the quantum critical regime near a d-wave Pomeranchuk instability in two dimensions. The transport decay rate is linear in temperature everywh…

Renormalized mean-field analysis of antiferromagnetism and d-wave superconductivity in the two-dimensional Hubbard model

J. Reiss, D. Rohe, W. Metzner

We analyze the competition between antiferromagnetism and superconductivity in the two-dimensional Hubbard model by combining a functional renormalization group flow with a mean-fi…

Exchange interaction between single magnetic adatoms

P. Wahl, P. Simon, L. Diekhoener +4

The magnetic coupling between single Co atoms adsorbed on a copper surface is determined by probing the Kondo resonance using low-temperature scanning tunneling spectroscopy. The K…

Mechanism of the Verwey transition in magnetite

P. Piekarz, K. Parlinski, A. M. Oles

By combining {\it ab initio} results for the electronic structure and phonon spectrum with the group theory, we establish the origin of the Verwey transition in FeO. Two pr…
