Riemannian Manifold HMC with fermions
Chulwoo Jung, Norman H. Christ
We report on our study of the Riemannian Manifold HMC (RMHMC) algorithm with the mass term for the gauge momenta replaced by rational functions of the gauge covariant Laplace opera…
Domain wall QCD with physical quark masses
RBC, UKQCD collaborations, : +21
We present results for several light hadronic quantities (, , , , , , ) obtained from simulations of 2+1 flavor domain wall lattice QCD…
Emerging understanding of the ΔI = 1/2 Rule from Lattice QCD
P. A. Boyle, N. H. Christ, N. Garron +8
There has been much speculation as to the origin of the ΔI = 1/2 rule (Re A_0/Re A_2 \simeq 22.5). We find that the two dominant contributions to the ΔI=3/2, K \to ππ correlation f…
Hardware and software status of QCDOC
P. A. Boyle, D. Chen, N. H. Christ +16
QCDOC is a massively parallel supercomputer whose processing nodes are based on an application-specific integrated circuit (ASIC). This ASIC was custom-designed so that crucial lat…
Status of and performance estimates for QCDOC
P. Boyle, D. Chen, N. H. Christ +14
QCDOC is a supercomputer designed for high scalability at a low cost per node. We discuss the status of the project and provide performance estimates for large machines obtained fr…
Kaon Matrix Elements and CP-violation from Quenched Lattice QCD: (I) the 3-flavor case
T. Blum, P. Chen, N. Christ +12
We report the results of a calculation of the K --> pi pi matrix elements relevant for the $\DIhalf$ rule and $\epe$ in quenched lattice QCD using domain wall fermions at a fixed l…
Chirality Correlation within Dirac Eigenvectors from Domain Wall Fermions
T. Blum, N. Christ, C. Cristian +6
In the dilute instanton gas model of the QCD vacuum, one expects a strong spatial correlation between chirality and the maxima of the Dirac eigenvectors with small eigenvalues. Fol…
Non-perturbative Renormalisation of Domain Wall Fermions: Quark Bilinears
T. Blum, N. Christ, C. Cristian +9
We find the renormalisation coefficients of the quark field and the flavour non-singlet fermion bilinear operators for the domain wall fermion action, in the regularisation indepen…
QCDOC: A 10-teraflops scale computer for lattice QCD
D. Chen, N. H. Christ, C. Cristian +10
The architecture of a new class of computers, optimized for lattice QCD calculations, is described. An individual node is based on a single integrated circuit containing a PowerPC…
Quenched Lattice QCD with Domain Wall Fermions and the Chiral Limit
T. Blum, P. Chen, N. Christ +16
Quenched QCD simulations on three volumes, , and and three couplings, , 5.85 and 6.0 using domain wall fermions provide a consiste…
The finite temperature QCD phase transition with domain wall fermions
P. Chen, N. Christ, G. Fleming +8
The domain wall formulation of lattice fermions is expected to support accurate chiral symmetry, even at finite lattice spacing. Here we attempt to use this new fermion formulation…
The finite temperature QCD phase transition with domain wall fermions
Pavlos Vranas
Results from the Columbia lattice group study of the QCD finite temperature phase transition with dynamical domain wall fermions on lattices are presented. These re…
Status of the 0.8 Teraflops Supercomputer at Columbia
I. Arsenin, D. Chen, N. Christ +14
The first stage in the construction of the 0.8 Teraflops Supercomputer at Columbia, a working, two node parallel computer, has been successfully completed. The next stage, a 512 no…
