Finite-size scaling in the interfacial stiffness of rough elastic contacts
Lars Pastewka, Nikolay Prodanov, Boris Lorenz +3
The total elastic stiffness of two contacting bodies with a microscopically rough interface has an interfacial contribution K that is entirely attributable to surface roughness. A…
Can the nearly conformal sextet gauge model hide the Higgs impostor?
Zoltán Fodor, Kieran Holland, Julius Kuti +3
New results are reported from large scale lattice simulations of a frequently discussed strongly interacting gauge theory with a fermion flavor doublet in the two-index symmetric (…
Nucleon Structure from Lattice QCD Using a Nearly Physical Pion Mass
J. R. Green, M. Engelhardt, S. Krieg +3
We report the first Lattice QCD calculation using the almost physical pion mass mpi=149 MeV that agrees with experiment for four fundamental isovector observables characterizing th…
Event-based simulation of neutron interferometry experiments
Hans De Raedt, Fengping Jin, Kristel Michielsen
A discrete-event approach, which has already been shown to give a cause-and-effect explanation of many quantum optics experiments, is applied to single-neutron interferometry exper…
Meson and Baryon dispersion relations with Brillouin fermions
Stephan Durr, Giannis Koutsou, Thomas Lippert
We study the dispersion relations of mesons and baryons built from Brillouin quarks on one N_f=2 gauge ensemble provided by QCDSF. For quark masses up to the physical strange quark…
Empirical characteristics of different types of pedestrian streams
Jun Zhang, Armin Seyfried
Reliable empirical data and proper understanding of pedestrian dynamics are necessary for fire safety design. However, specifications and data in different handbooks as well as exp…
Experimental study of pedestrian flow through a T-junction
Jun Zhang, Wolfram Klingsch, Andreas Schadschneider +1
In this study, series of experiments under laboratory conditions were carried out to investigate pedestrian flow through a T-junction, i.e., two branches merging into the main stre…
<x>_{u-d} from lattice QCD at nearly physical quark masses
Gunnar S. Bali, Sara Collins, Mridupawan Deka +7
We determine the second Mellin moment of the isovector quark parton distribution function <x>_{u-d} from lattice QCD with N_f=2 sea quark flavours, employing the non-perturbatively…
Nucleon Scalar and Tensor Charges from Lattice QCD with Light Wilson Quarks
J. R. Green, J. W. Negele, A. V. Pochinsky +3
We present 2+1 flavor Lattice QCD calculations of the nucleon scalar and tensor charges. Using the BMW clover-improved Wilson action with pion masses between 150 and 350 MeV and th…
QCD quark condensate in external magnetic fields
G. S. Bali, F. Bruckmann, G. Endrodi +3
We present a comprehensive analysis of the light condensates in QCD with 1+1+1 sea quark flavors (with mass-degenerate light quarks of different electric charges) at zero and nonze…
Block Iterative Eigensolvers for Sequences of Correlated Eigenvalue Problems
Edoardo Di Napoli, Mario Berljafa
In Density Functional Theory simulations based on the LAPW method, each self-consistent field cycle comprises dozens of large dense generalized eigenproblems. In contrast to real-s…
Isospin breaking in octet baryon mass splittings
R. Horsley, J. Najjar, Y. Nakamura +4
Using an SU(3) flavour symmetry breaking expansion in the quark mass, we determine the QCD component of the nucleon, Sigma and Xi mass splittings of the baryon octet due to up-down…
Towards the field binary population: Influence of orbital decay on close binaries
Christina Korntreff, Thomas Kaczmarek, Susanne Pfalzner
Surveys of the binary populations in the solar neighbourhood have shown that the periods of G- and M-type stars are log-normally distributed. However, observations of young binary…
A Lattice Study of the Glue in the Nucleon
R. Horsley, R. Millo, Y. Nakamura +7
By introducing an additional operator into the action and using the Feynman-Hellmann theorem we describe a method to determine both the quark line connected and disconnected terms…

Szabolcs Borsanyi, Stephan Durr, Zoltan Fodor +4
We extract the next-to-leading-order low-energy constants \bar\ell_3 and \bar\ell_4 of SU(2) chiral perturbation theory, based on precise lattice data for the pion mass and decay c…

S. Borsanyi, S. Durr, Z. Fodor +7
QCD thermodynamics is considered using Wilson fermions in the fixed scale approach. The temperature dependence of the renormalized chiral condensate, quark number susceptibility an…

I. C. Cloët, R. Horsley, J. T. Londergan +9
We present the first determination of charge symmetry violation (CSV) in the spin-dependent parton distribution functions of the nucleon. This is done by determining the first two…
