Distributing the chiral and flavour components of Dirac-Kahler fermions across multiple lattices
Steven Watterson, J. Sexton
We use a specific implementation of discrete differential geometry to describe Dirac-Kahler fermions in such a way that we can separate their chiral and flavour components. The for…
QCD on the BlueGene/L Supercomputer
G. Bhanot, D. Chen, A. Gara +2
In June 2004 QCD was simulated for the first time at sustained speed exceeding 1 TeraFlops in the BlueGene/L supercomputer at the IBM T.J. Watson Research Lab. The implementation a…
Chiral Dirac fermions on the lattice using Geometric Discretisation
Vivien de Beauce, Samik Sen, James C. Sexton
A new approach to the problem of doubling is presented with the Dirac-Kahler (DK) theory as a starting point and using Geometric Discretisation providing us with a new way of extra…
Chiral Dirac Fermions on the Lattice using Geometric Discretisation
Vivien de Beauce, Samik Sen
We propose a discretisation scheme based on the Dirac-Kahler formalism (DK) in which the algebraic relations between continuum operators are captured by their…
Multiple molecular dynamics time-scales in Hybrid Monte Carlo fermion simulations
Mike Peardon, James Sexton
A scheme for separating the high- and low-frequency molecular dynamics modes in Hybrid Monte Carlo (HMC) simulations of gauge theories with dynamical fermions is presented. The alg…
The Weakly Coupled Gross-Neveu Model with Wilson Fermions
R. Kenna, J. C. Sexton
The nature of the phase transition in the lattice Gross-Neveu model with Wilson fermions is investigated using a new analytical technique. This involves a new type of weak coupling…
