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…
Optical conductivity near finite-wavelength quantum criticality
S. Caprara, M. Grilli, C. Di Castro +1
We study the optical conductivity sigma(Omega) of an electron system near a quantum-critical point with finite-wavelength ordering. sigma(Omega) vanishes in clean Galilean-invarian…
Temperature induced phase averaging in one-dimensional mesoscopic systems
Severin G. Jakobs, Volker Meden, Herbert Schoeller +1
We analyse phase averaging in one-dimensional interacting mesoscopic systems with several barriers and show that for incommensurate positions an independent average over several ph…
On the identification of quasiprimary scaling operators in local scale-invariance
Malte Henkel, Tilman Enss, Michel Pleimling
The relationship between physical observables defined in lattice models and the associated (quasi-)primary scaling operators of the underlying field-theory is revisited. In the con…
A novel approach to transport through correlated quantum dots
C. Karrasch, T. Enss, V. Meden
We investigate the effect of local Coulomb correlations on electronic transport through a variety of coupled quantum dot systems connected to Fermi liquid leads. We use a newly dev…
