Cluster Functional Renormalization Group
Functional renormalization group (FRG) has become a diverse and powerful tool to derive effective low-energy scattering vertices of interacting many-body systems. Starting from a non-interacting expansion point of the action, the flow of the RG parameter Λ allows to trace the evolution of the effective one-particle and two-particle vertices towards low energies by taking into account the vertex...
متن کاملFermionic Functional Integrals and the Renormalization Group
The Renormalization Group is the name given to a technique for analyzing the qualitative behaviour of a class of physical systems by iterating a map on the vector space of interactions for the class. In a typical non-rigorous application of this technique one assumes, based on one’s physical intuition, that only a certain finite dimensional subspace (usually of dimension three or less) is impor...
متن کاملAntiferromagnetism with Ultracold Atoms
We use ultracold spin–1/2 atomic fermions (Li) to realize the Hubbard model on a three-dimensional (3D) optical lattice. At relatively high temperatures and at densities near half-filling, we show that the gas forms a Mott insulator with unordered spins. To observe antiferromagnetic order that is predicted to occur at lower temperatures, we developed the compensated optical lattice method to ev...
متن کاملIsing exponents from the functional renormalization group
We study the 3d Ising universality class using the functional renormalization group. With the help of background fields and a derivative expansion up to fourth order we compute the leading index, the subleading symmetric and antisymmetric corrections to scaling, the anomalous dimension, the scaling solution, and the eigenperturbations at criticality. We also study the cross correlations of scal...
متن کاملRenormalization group approach for electronic excitations in atoms
We present a finite size numerical renormalization group approach to obtain low-lying electronic excitations in atoms and molecules. Results show that the method is reasonably accurate for estimating the electronic excitations for carbon and silicon atoms. The method is general and has potential applicability for molecular systems. q 1998. Published by Elsevier Science B.V. All rights reserved.
