Isospin breaking corrections to a lattice QCD calculation of
Norman H. Christ, Erik Lundstrum
Because of the rule, the effects of electromagnetism and the isospin-breaking light quark mass difference on the direct CP violation parameter may be as…

Extended framework for the hybrid Monte Carlo in lattice gauge theory
Norman H. Christ, Lu-Chang Jin, Christoph Lehner +2
We develop an extended framework for the hybrid Monte Carlo (HMC) algorithm in lattice gauge theory by embedding the group into the space of general complex matrices,$M_N(\…

Generalized HMC using Nambu mechanics for lattice QCD
Erik Lundstrum
I describe a generalization of the hybrid Monte Carlo (HMC) algorithm in which the molecular dynamics (MD) steps utilize Nambu generalized Hamiltonian dynamics. Characterized by mu…
