A modified Cayley transform for SU(3) molecular dynamics simulations
Kevin Schäfers, Michael Peardon, Michael Günther
We propose a modification to the Cayley transform that defines a suitable local parameterization for the special unitary group . The new mapping is used to construc…
Constrained Hybrid Monte Carlo algorithms for gauge-Higgs models
Michael Günther, Roman Höllwieser, Francesco Knechtli
We develop Hybrid Monte Carlo (HMC) algorithms for constrained Hamiltonian systems of gauge- Higgs models and introduce a new observable for the constraint effective Higgs potentia…
The Wilson Flow and the finite temperature phase transition
Michèle Wandelt, Francesco Knechtli, Michael Günther
We consider the determination of the finite temperature phase transition in the Yang--Mills SU(3) gauge theory. We compute the difference of the spatial and temporal energy density…
Accuracy of Symmetric Partitioned Runge-Kutta Methods for Differential Equations on Lie-Groups
Michael Striebel, Michael Günther, Francesco Knechtli +1
Computer simulations in QCD are based on the discretization of the theory on a Euclidean lattice. To compute the mean value of an observable, usually the Hybrid Monte Carlo method…
Symmetric Partitioned Runge-Kutta Methods for Differential Equations on Lie Groups
Michèle Wandelt, Michael Günther, Francesco Knechtli +1
In this paper, we develop a higher order symmetric partitioned Runge-Kutta method for a coupled system of differential equations on Lie groups. We start with a discussion on partit…
