Comparison of bidirectional pedestrian flows by experiments
Jun Zhang, Armin Seyfried
Intersections of pedestrian flows feature multiple types, varying in the numbers of flow directions as well as intersecting angles. In this article results from diverse bidirection…
On the contact area and mean gap of rough, elastic contacts: Dimensional analysis, numerical corrections and reference data
Nikolay Prodanov, Wolf B. Dapp, Martin H. Müser
The description of elastic, nonadhesive contacts between solids with self-affine surface roughness seems to necessitate knowledge of a large number of parameters. However, few para…
Event-based simulation of quantum physics experiments
Kristel Michielsen, Hans De Raedt
We review an event-based simulation approach which reproduces the statistical distributions of wave theory not by requiring the knowledge of the solution of the wave equation of th…
Universal flow-density relation of single-file bicycle, pedestrian and car motion
Jun Zhang, Wolfgang Mehner, Stefan Holl +4
The relation between flow and density is an essential quantitative characteristic to describe the efficiency of traffic systems. We have performed experiments with single-file moti…
SU(3) flavour symmetry breaking and charmed states
R. Horsley, J. Najjar, Y. Nakamura +7
By extending the SU(3) flavour symmetry breaking expansion from up, down and strange sea quark masses to partially quenched valence quark masses we propose a method to determine ch…
SU(3) flavour breaking and baryon structure
A. N. Cooke, R. Horsley, Y. Nakamura +6
We present results from the QCDSF/UKQCD collaboration for hyperon electromagnetic form factors and axial charges obtained from simulations using Nf=2+1 flavours of O(a)-improved Wi…
Electromagnetic splitting of quark and pseudoscalar meson masses from dynamical QCD + QED
R. Horsley, Y. Nakamura, D. Pleiter +5
Lattice QCD simulations are now reaching a precision where electromagnetic corrections from QED become important. In investigating the effects of SU(3) breaking due to quark mass d…
Nucleon form factors with light Wilson quarks
Jeremy Green, Michael Engelhardt, Stefan Krieg +4
We present nucleon observables - primarily isovector vector form factors - from calculations using 2+1 flavors of Wilson quarks. One ensemble is used for a dedicated high-precision…
Lattice QCD at the physical point meets SU(2) chiral perturbation theory
Stephan Durr, Zoltan Fodor, Christian Hoelbling +9
We perform a detailed, fully-correlated study of the chiral behavior of the pion mass and decay constant, based on 2+1 flavor lattice QCD simulations. These calculations are implem…
Screening and Collective Modes in Disordered Graphene Antidot Lattices
Shengjun Yuan, Fengping Jin, Rafael Roldán +2
The excitation spectrum and the collective modes of graphene antidot lattices (GALs) are studied in the context of a -band tight-binding model. The dynamical polarizability and…
Towards time-dependent, non-equilibrium charge-transfer force fields: Contact electrification and history-dependent dissociation limits
Wolf B. Dapp, Martin H. Müser
Force fields uniquely assign interatomic forces for a given set of atomic coordinates. The underlying assumption is that electrons are in their quantum-mechanical ground state or i…
Self-Affine Elastic Contacts: Percolation and Leakage
Wolf B. Dapp, Andreas Lücke, Bo N. J. Persson +1
We study fluid flow at the interfaces between elastic solids with randomly rough, self-affine surfaces. We show by numerical simulation that elastic deformation lowers the relative…
Redox reactions with empirical potentials: Atomistic battery discharge simulations
Wolf B. Dapp, Martin H. Müser
Batteries are pivotal components in overcoming some of today's greatest technological challenges. Yet to date there is no self-consistent atomistic description of a complete batter…
Efficient estimation of eigenvalue counts in an interval
Edoardo Di Napoli, Eric Polizzi, Yousef Saad
Estimating the number of eigenvalues located in a given interval of a large sparse Hermitian matrix is an important problem in certain applications and it is a prerequisite of eige…
Towards an Efficient Use of the BLAS Library for Multilinear Tensor Contractions
Edoardo Di Napoli, Diego Fabregat-Traver, Gregorio Quintana-Ortì +1
Mathematical operators whose transformation rules constitute the building blocks of a multi-linear algebra are widely used in physics and engineering applications where they are ve…
A multi-level spectral deferred correction method
Robert Speck, Daniel Ruprecht, Matthew Emmett +3
The spectral deferred correction (SDC) method is an iterative scheme for computing a higher-order collocation solution to an ODE by performing a series of correction sweeps using a…
Isospin splittings in the light baryon octet from lattice QCD and QED
Sz. Borsanyi, S. Dürr, Z. Fodor +11
While electromagnetic and up-down quark mass difference effects on octet baryon masses are very small, they have important consequences. The stability of the hydrogen atom against…
Is there a flavor hierarchy in the deconfinement transition of QCD?
Rene Bellwied, Szabolcs Borsanyi, Zoltan Fodor +2
We present possible indications for flavor separation during the QCD crossover transition based on continuum extrapolated lattice QCD calculations of higher order susceptibilities.…
Freeze-out parameters: lattice meets experiment
S. Borsanyi, Z. Fodor, S. D. Katz +3
We present our results for ratios of higher order fluctuations of electric charge as functions of the temperature. These results are obtained in a system of 2+1 quark flavors at ph…
A Parallel and Scalable Iterative Solver for Sequences of Dense Eigenproblems Arising in FLAPW
Mario Berljafa, Edoardo Di Napoli
In one of the most important methods in Density Functional Theory - the Full-Potential Linearized Augmented Plane Wave (FLAPW) method - dense generalized eigenproblems are organize…
Quantum theory as the most robust description of reproducible experiments
H. De Raedt, M. I. Katsnelson, K. Michielsen
It is shown that the basic equations of quantum theory can be obtained from a straightforward application of logical inference to experiments for which there is uncertainty about i…
Atomistic modelling of friction of Cu and Au nanoparticles adsorbed on graphene

We present classical molecular dynamics calculations of the behavior of copper and gold nanoparticles on a graphene sheet, sheared with a constant applied force . The fo…
Taste-split staggered actions: eigenvalues, chiralities and Symanzik improvement
Stephan Durr
The eigenvalue spectra of staggered fermions with an Adams and/or Hoelbling mass term are studied. The chiralities of the eigenmodes reflect whether the chirality linked to the unf…
