QCD on the Cell Broadband Engine
F. Belletti, G. Bilardi, M. Drochner +16
We evaluate IBM's Enhanced Cell Broadband Engine (BE) as a possible building block of a new generation of lattice QCD machines. The Enhanced Cell BE will provide full support of do…
Quantitative comparison of filtering methods in lattice QCD
Falk Bruckmann, Christof Gattringer, Ernst-Michael Ilgenfritz +3
We systematically compare filtering methods used to extract topological excitations (like instantons, calorons, monopoles and vortices) from lattice gauge configurations, namely AP…
Low-lying spectrum for lattice Dirac operators with twisted mass
Christof Gattringer, Stefan Solbrig
We analyze the low-lying spectrum and eigenmodes of lattice Dirac operators with a twisted mass term. The twist term expels the eigenvalues from a strip in the complex plane and al…
Topologically non-trivial field configurations - interplay of vortices and Dirac eigenmodes
Stefan Solbrig, Jochen Gattnar, Christof Gattringer +4
Gluon field configurations with non-trivial topology like instantons, magnetic monopoles and center vortices play a crucial role in QCD and, in particular, for the spontaneous brea…
Dependence of Dirac eigenmodes on boundary conditions for SU(2) lattice gauge theory
Christof Gattringer, Stefan Solbrig
We analyze zero modes of the Dirac operator for SU(2) lattice gauge theory. We find that the zero modes are strongly localized in all 4 directions. The position of these lumps depe…
