Heavy Quarks on Anisotropic Lattices: The Charmonium Spectrum
Ping Chen
We present results for the mass spectrum of mesons simulated on anisotropic lattices where the temporal spacing is only half of the spatial spacing . The lat…
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…
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…
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…
