Journal ArticleDOI
Correlated lattice fermions in d=∞ dimensions
Walter Metzner,Dieter Vollhardt +1 more
TL;DR: In this paper, a new approach to correlated Fermi systems such as the Hubbard model, the periodic Anderson model etc. is discussed, which makes use of the limit of high spatial dimensions.
Journal ArticleDOI
Functional renormalization group approach to correlated fermion systems
TL;DR: The functional renormalization group as discussed by the authors is a flexible and unbiased tool for dealing with scale-dependent behavior of correlated fermion systems, such as Luttinger liquid behavior and the Kondo effect.
Journal ArticleDOI
d-wave superconductivity and pomeranchuk instability in the two-dimensional hubbard model
TL;DR: The flow of effective interactions and susceptibilities confirms the expected existence of a d-wave pairing instability driven by antiferromagnetic spin fluctuations and finds that strong forward scattering interactions develop which may lead to a Pomeranchuk instability breaking the tetragonal symmetry of the Fermi surface.
Journal ArticleDOI
From stimulus encoding to feature extraction in weakly electric fish
TL;DR: In this paper, the authors applied a stimulus estimation method and a signal-detection method to both P-receptor afferents and their targets, the pyramidal cells in the electrosensory lateral line lobe.
Journal ArticleDOI
Renormalization-group analysis of the two-dimensional Hubbard model
TL;DR: In this article, a renormalization-group method for interacting Fermi systems was developed, where the complete flow from the bare action of a microscopic model to the effective low-energy action, as a function of a continuously decreasing infrared cutoff, is given by a differential flow equation which is local in the flow parameter.
