staggered fermions ∗
We address the locality problem arising in simulations, which take the square root of the staggered fermion determinant as a Boltzmann weight to reduce the number of dynamical quark tastes from four to two. We study analytically and numerically the square root of the staggered fermion operator as a candidate to define a two taste theory from first principles. Although it has the correct weight,...
متن کاملStaggered Chiral Perturbation Theory for All-Staggered Heavy-Light Mesons
In HISQ simulations by the MILC and Fermilab Lattice collaborations, both the light quarks and the charm quark are staggered. We extend staggered chiral perturbation theory (S χ PT) to include such all-staggered heavy-light mesons. We assume that the heavy quark action is sufficiently improved that we may take am Q << 1 (where m Q is the heavy quark mass), but also that m Q >> Λ QCD so that a c...
متن کاملStaggered Price-Setting, Staggered Wage-Setting, and Business Cycle Persistence∗
Staggered price-setting and staggered wage-setting are commonly viewed as similar mechanisms in generating persistent real effects of monetary shocks. In this paper, we distinguish the two mechanisms in a dynamic stochastic general equilibrium framework. We show that, although the dynamic pricesetting and wage-setting equations are alike, a key parameter governing persistence is linked to the u...
متن کاملOn Endogenously Staggered Prices
Taylor's model of staggered contracts is an in uential explanation for nominal inertia and the persistent real e ects of nominal shocks. However, in standard imperfect competition models, if agents are allowed to choose the timing of pricing decisions, they will typically choose to synchronize. This paper provides a simple model of imperfect competition which produces stable staggering. Our arg...
متن کاملStaggered Consistent Checkpointing
ÐA consistent checkpointing algorithm saves a consistent view of a distributed application's state on stable storage. The traditional consistent checkpointing algorithms require different processes to save their state at about the same time. This causes contention for the stable storage, potentially resulting in large overheads. Staggering the checkpoints taken by various processes can reduce c...
