Testing Algorithms for Finite Temperature Lattice QCD
Nuclear Physics A(2007)
摘要
We discuss recent algorithmic improvements in simulating finite temperature
QCD on a lattice. In particular, the Rational Hybrid Monte Carlo(RHMC)
algorithm is employed to generate lattice configurations for 2+1 flavor QCD.
Unlike the Hybrid R Algorithm, RHMC is reversible, admitting a Metropolis
accept/reject step that eliminates the $\mathcal{O}(\delta t^2)$ errors
inherent in the R Algorithm. We also employ several algorithmic speed-ups,
including multiple time scales, the use of a more efficient numerical
integrator, and Hasenbusch pre-conditioning of the fermion force.
