Adapted nested force-gradient integrators: the Schwinger model case
Dmitry Shcherbakov, Matthias Ehrhardt, Jacob Finkenrath +3
We study a novel class of numerical integrators, the adapted nested force-gradient schemes, used within the molecular dynamics step of the Hybrid Monte Carlo (HMC) algorithm. We te…
Force-Gradient Nested Multirate Methods for Hamiltonian System
Dmitry Shcherbakov, Matthias Ehrhardt, Michael Günther +1
Force-gradient decomposition methods are used to improve the energy preservation of symplectic schemes applied to Hamiltonian systems. If the potential is composed of different par…
Multistep Methods for Lattice QCD Simulations
Dmitry Shcherbakov, Matthias Ehrhardt
It is well-known that molecular dynamics integrators, which are used for lattice quantum chromodynamics (QCD), suffer from instabilities and possess a rather low order of the accur…
