The twelve-flavor -function and dilaton tests of the sextet scalar
Zoltan Fodor, Kieran Holland, Julius Kuti +2
We discuss near-conformal gauge theories beyond the standard model (BSM) where interesting results on the twelve-flavor -function of massless fermions in the fundamental represe…
Accelerating the computation of FLAPW methods on heterogeneous architectures
Davor Davidović, Diego Fabregat-Traver, Markus Höhnerbach +1
Legacy codes in computational science and engineering have been very successful in providing essential functionality to researchers. However, they are not capable of exploiting the…
User's guide to Monte Carlo methods for evaluating path integrals
Marise J. E. Westbroek, Peter R. King, Dimitri D. Vvedensky +1
We give an introduction to the calculation of path integrals on a lattice, with the quantum harmonic oscillator as an example. In addition to providing an explicit computational se…
Computing the nucleon charge and axial radii directly at in lattice QCD
Nesreen Hasan, Jeremy Green, Stefan Meinel +5
We describe a procedure for extracting momentum derivatives of nucleon matrix elements on the lattice directly at . This is based on the Rome method for computing momentum d…
Spectroscopy of the BSM sextet model
Zoltan Fodor, Kieran Holland, Julius Kuti +2
As part of our ongoing lattice study of SU(3) gauge theory with two flavors of fermions in the two-index symmetric representation (the sextet model), we present the current status…
A new method for the beta function in the chiral symmetry broken phase
Zoltan Fodor, Kieran Holland, Julius Kuti +2
We describe a new method to determine non-perturbatively the beta function of a gauge theory using lattice simulations in the p-regime of the theory. This complements alternative m…
Hadronic vacuum polarization contribution to the anomalous magnetic moments of leptons from first principles
Wuppertal collaboration, Sz. Borsanyi, Z. Fodor +9
We compute the leading, strong-interaction contribution to the anomalous magnetic moment of the electron, muon and tau using lattice quantum chromodynamics (QCD) simulations. Calcu…
Weakly coupled conformal gauge theories on the lattice
Zoltan Fodor, Kieran Holland, Julius Kuti +2
Results are reported for the beta-function of weakly coupled conformal gauge theories on the lattice, SU(3) with Nf=14 fundamental and Nf=3 sextet fermions. The models are chosen t…
Extended investigation of the twelve-flavor -function
Zoltan Fodor, Kieran Holland, Julius Kuti +2
We report new results from high precision analysis of an important BSM gauge theory with twelve massless fermion flavors in the fundamental representation of the SU(3) color gauge…
Extracting the Single-Particle Gap in Carbon Nanotubes with Lattice Quantum Monte Carlo
Evan Berkowitz, Christopher Koerber, Stefan Krieg +3
We show how lattice Quantum Monte Carlo simulations can be used to calculate electronic properties of carbon nanotubes in the presence of strong electron-electron correlations. We…
Collimated Ultra-Bright Gamma-Rays from a PW-Laser-Driven Wire Wiggler
W. -M. Wang, Z. -M. Sheng, P. Gibbon +3
It is shown by three-dimensional QED particle-in-cell simulation that as a laser pulse of 2.5 PW and 20 fs propagates along a sub-wavelength-wide solid wire, directional synchrotro…
Optimization of the Brillouin operator on the KNL architecture
Stephan Durr
Experiences with optimizing the matrix-times-vector application of the Brillouin operator on the Intel KNL processor are reported. Without adjustments to the memory layout, perform…
Non-Linear Least-Squares Optimization of Rational Filters for the Solution of Interior Eigenvalue Problems
Jan Winkelmann, Edoardo Di Napoli
Rational filter functions can be used to improve convergence of contour-based eigensolvers, a popular family of algorithms for the solution of the interior eigenvalue problem. We p…
Parallelizing spectral deferred corrections across the method
Robert Speck
In this paper we present two strategies to enable "parallelization across the method" for spectral deferred corrections (SDC). Using standard low-order time-stepping methods in an…
Up, down, and strange nucleon axial form factors from lattice QCD
Jeremy Green, Nesreen Hasan, Stefan Meinel +7
We report a calculation of the nucleon axial form factors and for all three light quark flavors in the range $0\leq Q^2\lesssim 1.2\text{…
Collective phenomena in crowds - where pedestrian dynamics need social psychology
Anna Sieben, Jette Schumann, Armin Seyfried
This article is on collective phenomena in pedestrian dynamics during the assembling and dispersal phases of gatherings. To date pedestrian dynamics have been primarily studied in…
Electromagnetic form factors at large momenta from lattice QCD
A. J. Chambers, J. Dragos, R. Horsley +10
Accessing hadronic form factors at large momentum transfers has traditionally presented a challenge for lattice QCD simulations. Here we demonstrate how a novel implementation of t…
Constraining the hadronic spectrum through QCD thermodynamics on the lattice
Paolo Alba, Rene Bellwied, Szabolcs Borsanyi +9
Fluctuations of conserved charges allow to study the chemical composition of hadronic matter. A comparison between lattice simulations and the Hadron Resonance Gas (HRG) model sugg…
Charge diffusion in the one-dimensional Hubbard model
R. Steinigeweg, F. Jin, H. De Raedt +2
We study the real-time and real-space dynamics of charge in the one-dimensional Hubbard model in the limit of high temperatures. To this end, we prepare pure initial states with sh…
