Accelerating the hybrid Monte Carlo algorithm
Physics Letters B, 2003 An algorithm for separating the high- and low-frequency molecular dynamics modes in Hybrid Monte Carlo simulations of gauge theories with dynamical fermions is presented. The separation is based on splitting the pseudo-fermion action into two parts, as was initially proposed by Hasenbusch.

ODD-FLAVOR SIMULATIONS BY HYBRID MONTE CARLO [PDF]
Non-Perturbative Methods and Lattice QCD, 2001 The standard hybrid Monte Carlo algorithm is known to simulate even flavors QCD only. Simulations of odd flavors QCD, however, can be also performed in the framework of the hybrid Monte Carlo algorithm where the inverse of the fermion matrix is approximated by a polynomial. In this exploratory study we perform three flavors QCD simulations.

A hybrid approach for neutronics calculations in the neutron shielding of sodium fast reactors
EPJ Nuclear Sciences & Technologies, 2021 Neutron calculations in the neutron shielding of fast neutron reactors are a complex problem as deterministic schemes are usually not suited for such calculations while Monte-Carlo codes have poor computational performance due to the very low flux levels
