Critical Behavior at the Chiral Phase Transition
C. Bernard, T. Blum, C. E. DeTar +8
Quantum chromodynamics with two zero mass flavors is expected to exhibit a phase transition with O(4) critical behavior. Fixing the universality class is important for phenomenolog…
Krylov space solvers for shifted linear systems
B. Jegerlehner
We investigate the application of Krylov space methods to the solution of shifted linear systems of the form (A+σ) x - b = 0 for several values of σsimultaneously, using only as ma…
Improvements of the local bosonic algorithm
B. Jegerlehner
We report on several improvements of the local bosonic algorithm proposed by M. Luescher. We find that preconditioning and over-relaxation works very well. A detailed comparison be…
Some aspects of simulation algorithms for dynamical fermions
Karl Jansen, Beat Jegerlehner, Chuan Liu
Three topics concerning fermion simulation algorithms are discussed: 1.) A performance comparison of the multiboson technique to simulate dynamical fermions and the Kramers equatio…
Performance Tests of the Kramers Equation and Boson Algorithms for Simulations of QCD
Karl Jansen, Beat Jegerlehner, Chuan Liu
We present a performance comparison of the Kramers equation and the boson algorithms for simulations of QCD with two flavors of dynamical Wilson fermions and gauge group . R…
Improvements of Lüscher's local bosonic fermion algorithm
Beat Jegerlehner
We discuss the application of hybrid over-relaxation, even-odd preconditioning and a modified local updating procedure to the local bosonic fermion algorithm. Studies on autocorrel…
