Effective interactions in multi-band systems from constrained summations
Carsten Honerkamp
In correlated electron materials, the application of many-body techniques for the study of interaction effects or unconventional superconductivity often requires the formulation of…
Instabilities of interacting electrons on the honeycomb bilayer
Michael M. Scherer, Stefan Uebelacker, Carsten Honerkamp
We investigate the instabilities of interacting electrons on the honeycomb bilayer by means of the functional renormalization group for a range of interactions up to the third-near…
Spectral properties of one-dimensional spiral spin density wave states
Dirk Schuricht
We provide a full characterization of the spectral properties of spiral spin density wave (SSDW) states which emerge in one-dimensional electron systems coupled to localized magnet…
Effective three-particle interactions in low-energy models for multiband systems
Stefan A. Maier, Carsten Honerkamp
We discuss different approximations for effective low-energy interactions in multi-band models for weakly correlated electrons. In the study of Fermi surface instabilities of the c…
A renormalization group approach to time dependent transport through correlated quantum dots
D. M. Kennes, S. G. Jakobs, C. Karrasch +1
We introduce a real time version of the functional renormalization group which allows to study correlation effects on nonequilibrium transport through quantum dots. Our method is e…
Local spectral properties of Luttinger liquids: scaling versus nonuniversal energy scales
D. Schuricht, S. Andergassen, V. Meden
Motivated by recent scanning tunneling and photoemission spectroscopy measurements on self-organized gold chains on a germanium surface we reinvestigate the local single-particle s…
