Simulations for CLIC Drive Beam Linac
Simulations CLIC Drive Beam Linac Compact Linear Collider
2012/2/28
The Drive Beam Linac of the Compact Linear Collider (CLIC) has to accelerate an electron beam with 4.2 A up to 2.4 GeV in almost fully-loaded structures. The pulse contains about 70000 bunches, one in...
N-body Simulations for f(R) Gravity using a Self-adaptive Particle-Mesh Code
N-body Simulations Gravity Self-adaptive Particle-Mesh Code
2010/12/24
We perform high resolution N-body simulations for f(R) gravity based on a self-adaptive particle- mesh code MLAPM. The Chameleon mechanism that recovers General Relativity on small scales is fully ta...
Supersymmetry on the lattice and the status of the Super-Yang-Mills simulations
the lattice the Super-Yang-Mills simulations
2011/1/6
Supersymmetry (SUSY) and supersymmetric field theories are an interesting topic for numerical lattice simulations. Similar to the chiral symmetry there is also no local realization of (interacting) su...
Better HMC integrators for dynamical simulations
Better HMC integrators dynamical simulations
2011/1/6
We show how to improve the molecular dynamics step of Hybrid Monte Carlo, both by tuning the integrator using Poisson brackets measurements and by the use of force gradient integrators. We present res...
Autocorrelations in Hybrid Monte Carlo Simulations
Autocorrelations Hybrid Monte Carlo Simulations

Simulations of QCD suffer from severe critical slowing down towards the continuum limit. This problem is known to be prominent in the topological charge, however, all observables are affected to vario...
