Algebraic Multigrid for Disordered Systems and Lattice Gauge Theories
Christoph Best
The construction of multigrid operators for disordered linear lattice operators, in particular the fermion matrix in lattice gauge theories, by means of algebraic multigrid and blo…
Wavelet-induced renormalization group for the Landau-Ginzburg model
Christoph Best
The scale hierarchy of wavelets provides a natural frame for renormalization. Expanding the order parameter of the Landau-Ginzburg/ model in a basis of compact orthonormal wav…
QCD on α-Clusters
N. Eicker, C. Best, Th. Lippert +1
It is shown that the 21264 Alpha processor can reach about 20% sustained efficiency for the inversion of the Wilson-Dirac operator. Since fast ethernet is not sufficient to get bal…
Pion and Rho Structure Functions from Lattice QCD
C. Best, M. Göckeler, R. Horsley +7
We calculate the lower moments of the deep-inelastic structure functions of the pion and the rho meson on the lattice. Of particular interest to us are the spin-dependent structure…
A microscopic semiclassical confining field equation for lattice gauge theory in 2+1 dimensions
Christoph Best, Andreas Schaefer
We present a semiclassical nonlinear field equation for the confining field in 2+1--dimensional lattice gauge theory (compact QED). The equation is derived directly from the…
U(1) flux tube profiles from Hamiltonian lattice gauge theory using a random walk ground-state projector
Christoph Best, Andreas Schäfer
We use a self-guided random walk to solve the ground-state problem of Hamiltonian U(1) pure gauge theory in 2+1 dimensions in the string sector. By making use of the electric-field…
