We propose a modification of the Hybrid-Monte-Carlo algorithm that allows for a larger step-size of the integration scheme at constant acceptance rate. The key ingredient is that the pseudo-fermion action is split into two parts. We test our proposal at the example of the two-dimensional lattice Schwinger model with two degenerate flavours of Wilson-fermions.

  1. Pion condensation at non-zero isospin chemical potential with Wilson fermions

    hep-lat 2025-02 conditional novelty 5.0 of 10

    Using Wilson fermions on the lattice, the onset of pion condensation is observed at an isospin chemical potential slightly below m_pi/2, consistent with earlier staggered-fermion results.

  2. Hybrid calculation of hadronic vacuum polarization in muon g-2 to 0.48\%

    hep-lat 2024-07 unverdicted novelty 4.0 of 10

    Lattice QCD on finer grids yields a_μ^LO-HVP = 715.1(3.4)×10^{-10}, producing a standard-model prediction for a_μ that differs from experiment by only 0.5 sigma.
