Quark propagator on the Connection

چکیده
Lippert, T., K. Schilling and N. Petkov, Quark propagator on the Connection Machine, Parallel Computing 18 (1992) 1291-1299. The computation of the fermion propagator in lattice Quantum Chromodynamics requires the solution of a large system of linear equations. We discuss and compare the structure, implementation and performance of two linear equation solvers, the Jacobi algorithm and the Conjugate Gradient algorithm, on the Connection Machine CM-2. We investigate the computer time needed for next neighbor communication versus the time required for floating point operations on 84 and 164 lattices. We compare the convergence behavior of Conjugate Gradient and Jacobi as applied to gauge configurations at ~ = 0.0 and 6.0.

متن کاملAspects of Dynamical Chiral Symmetry Breaking
Dynamical chiral symmetry breaking is a nonperturbative phenomenon that may be studied using QCD’s gap equation. Model-independent results can be obtained with a nonperturbative and symmetry preserving truncation. The gap equation yields the massive dressed-quark propagator, which has a spectral representation when considered as a function of the current-quark mass. This enables an explication ...
متن کاملLattice quark propagator with staggered quarks in Landau and Laplacian gauges
We report on the lattice quark propagator using standard and improved Staggered quark actions, with the standard, Wilson gauge action. The standard Kogut-Susskind action has errors of O(a) while the “Asqtad” action has O(a), O(ag) errors. The quark propagator is interesting for studying the phenomenon of dynamical chiral symmetry breaking and as a test-bed for improvement. Gauge dependent quant...
متن کاملThe effect of the ultraviolet part of the gluon propagator on the heavy quark propagator
We revisit our recently proposed formalism for dealing with the heavy quark limit of the quark Dyson-Schwinger equation. An ambiguity inherent in the original version of method is identified and resolved. Our reanalysis illustrates the importance of correctly accounting for the effect of hard gluon momenta on the heavy quark self energy in the vicinity of the bare fermion mass pole. PACS NUMBER...
متن کاملInfrared and ultraviolet properties of the Landau gauge quark propagator
The quark propagator is a building block of Quantum Chromodynamics and has been studied in numerous formulations [1,2,3]. The lattice regularisation provides a method for a full nonperturbative calculation from first principles. In the infrared, the quark propagator displays dynamical mass generation, but in the ultraviolet it takes its perturbative, running form. By computing the quark propaga...
