A parallelizable SSOR preconditioning scheme for Krylov subspace iterative solvers in lattice QCD applications involving Wilson fermions is presented. In actual Hybrid Monte Carlo simulations and quark propagator calculations it helps to reduce the number of iterations by a factor of 2 compared to conventional odd-even preconditioning. This corresponds to a… (More)

We present the final analysis of the light and strange hadron spectra from a full QCD lattice simulation with two degenerate dynamical sea quark flavours at β = 5.6 on a 163 × 32 lattice. Four sets of sea quark masses corresponding to the range .69 ≤ mπ/mρ ≤ .83 are investigated. For reference we also ran a quenched simulation at βeff = 6.0, which is the… (More)

We describe results of a high-statistics finite size scaling analysis of 4d compact U(1) lattice gauge theory with Wilson action at the phase transition point. Using a multicanonical hybrid Monte Carlo algorithm we generate data samples with more than 150 tunneling events between the metastable states of the system, on lattice sizes up to 18. We performed a… (More)

We present a study of the SU(3) glueball spectrum for all J values at lattice spacings down to a = 3.73(6) GeV (β = 6.4) using lattices of size up to 32. We extend previous studies and show that the continuum limit has effectively been reached. The number of clearly identified J states has been substantially increased. There are no clear signals for… (More)

Gauge fixing is a frequent task encountered in practical lattice gauge theory calculations. We review the performance characteristics of some standard gauging procedures for non-Abelian gauge theories, implemented on the parallel machines CM2 and CM5. E-mail: suman@wptu23.physik.uni-wuppertal.de.

We explore the photophysics of P(NDI2OD-T2), a high-mobility and air-stable n-type donor/acceptor polymer. Detailed steady-state UV-vis and photoluminescence (PL) measurements on solutions of P(NDI2OD-T2) reveal distinct signatures of aggregation. By performing quantum chemical calculations, we can assign these spectral features to unaggregated and stacked… (More)

Progress in analytical ultracentrifugation (AUC) has been hindered by obstructions to hardware innovation and by software incompatibility. In this paper, we announce and outline the Open AUC Project. The goals of the Open AUC Project are to stimulate AUC innovation by improving instrumentation, detectors, acquisition and analysis software, and collaborative… (More)

We present results of a high statistics study of the chromo field distribution between static quarks in SU(2) gauge theory on lattices of volumes 16, 32, and 483×64, with physical extent ranging from 1.3 fm up to 2.7 fm at β = 2.5, β = 2.635, and β = 2.74. We establish string formation over physical distances as large as 2 fm. The results are tested against… (More)

The nature of the phase transition in compact QED has been under debate for long time. We have addressed this problem in high statistics runs to reach a final conclusion in that matter. An important ingredient of our approach is the finite size scaling (FSS) theory à la BorgsKotecky (BK) first established a long time ago in the context of strong first order… (More)
