A (P)HMC algorithm for N f = 2+1+1 flavours of twisted mass fermions

Abstract

We present a detailed design of a (P)HMC simulation algorithm for N f = 2 + 1 + 1 maximally twisted Wilson quark flavours. The algorithm retains even/odd and mass-shift preconditioning combined with multiple Molecular Dynamics time scales for both the light mass degenerate, u and d, quarks and the heavy mass non-degenerate, s and c, quarks. Various non… (More)
