Linear scaling electronic structure calculations and accurate sampling with noisy forces
Florian R. Krajewski, Michele Parrinello
Numerical simulations based on electronic structure calculations are finding ever growing applications in many areas of physics. A major limiting factor is however the cubic scalin…
Stochastic linear scaling for metals and non metals
Florian R. Krajewski, Michele Parrinello
Total energy electronic structure calculations, based on density functional theory or on the more empirical tight binding approach, are generally believed to scale as the cube of t…
Quantum creep and quantum creep transitions in 1D sine-Gordan chains
Florian R. Krajewski, Martin H. Müser
Discrete sine-Gordon (SG) chains are studied with path-integral molecular dynamics. Chains commensurate with the substrate show the transition from collective quantum creep to pinn…
QCD Analysis of hadronic tau lepton decays
F. Krajewski
Diploma paper written at the Johannes Gutenberg-Universitaet Mainz.
Comparison of two non-primitive methods for path integral simulations: Higher-order corrections vs. an effective propagator approach
Florian R. Krajewski, Martin H. Muser
Two methods are compared that are used in path integral simulations. Both methods aim to achieve faster convergence to the quantum limit than the so-called primitive algorithm (PA)…
Determination of the strange quark mass from Cabibbo-suppressed tau decays with resummed perturbation theory in an effective scheme
J. G. Koerner, F. Krajewski, A. A. Pivovarov
We present an analysis of the m_s^2-corrections to Cabibbo-suppressed tau lepton decays employing contour improved resummation within an effective scheme which is an essential new…
