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…
Toward the Chiral Limit of QCD: Quenched and Dynamical Domain Wall Fermions
Ping Chen, Norman Christ, Geoerge Fleming +7
A serious difficulty in conventional lattice field theory calculations is the coupling between the chiral and continuum limits. With both staggered and Wilson fermions, the chiral…
Quenched QCD with domain wall fermions
P. Chen, N. Christ, G. Fleming +7
We report on simulations of quenched QCD using domain wall fermions, where we focus on basic questions about the formalism and its ability to produce expected low energy hadronic p…
The domain wall fermion chiral condensate in quenched QCD
Ping Chen, Norman H. Christ, George R. Fleming +7
We examine the chiral limit of domain wall fermions in quenched QCD. One expects that in a quenched simulation, exact fermion zero modes will give a divergent, 1/m behavior in the…
Status of the QCDSP project
Dong Chen, Ping Chen, Norman H. Christ +15
We describe the completed 8,192-node, 0.4Tflops machine at Columbia as well as the 12,288-node, 0.6Tflops machine assembled at the RIKEN Brookhaven Research Center. Present perform…
Dynamical QCD thermodynamics with domain wall fermions
P. Chen, N. Christ, G. Fleming +7
We present results from numerical simulations of full, two flavor QCD thermodynamics at N_t=4 with domain wall fermions. For the first time a numerical simulation of the full QCD p…
Domain wall fermion zero modes on classical topological backgrounds
P. Chen, N. Christ, G. Fleming +6
The domain wall approach to lattice fermions employs an additional dimension, in which gauge fields are merely replicated, to separate the chiral components of a Dirac fermion. It…
QCDSP - A status report
QCDSP Collaboration, Dong Chen, Ping Chen +16
The QCDSP machine at Columbia University has grown to 2,048 nodes achieving a peak speed of 100 Gigaflops. Software for quenched and Hybrid Monte Carlo (HMC) evolution schemes has…
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…
