Determining the scale in Lattice QCD
V. G. Bornyakov, R. Horsley, R. Hudspith +8
We discuss scale setting in the context of 2+1 dynamical fermion simulations where we approach the physical point in the quark mass plane keeping the average quark mass constant. W…
Lattice QCD on Non-Orientable Manifolds
Simon Mages, Balint C. Toth, Szabolcs Borsanyi +3
A common problem in lattice QCD simulations on the torus is the extremely long autocorrelation time of the topological charge, when one approaches the continuum limit. The reason i…
Applications of the Feynman-Hellmann theorem in hadron structure
A. J. Chambers, R. Horsley, Y. Nakamura +8
The Feynman-Hellmann (FH) relation offers an alternative way of accessing hadronic matrix elements through artificial modifications to the QCD Lagrangian. In particular, a FH-motiv…
Hadronic form factors for rare semileptonic decays
Jonathan Flynn, Andreas Jüttner, Taichi Kawanai +2
We discuss first results for the computation of short distance contributions to semileptonic form factors for the rare decays and $B_s \to ϕ\ell^+ \e…
Jamming transitions in force-based models for pedestrian dynamics
Mohcine Chraibi, Takahiro Ezaki, Antoine Tordeux +3
Force-based models describe pedestrian dynamics in analogy to classical mechanics by a system of second order ordinary differential equations. By investigating the linear stability…
QCD thermodynamics with continuum extrapolated dynamical overlap fermions
Sz. Borsanyi, Z. Fodor S. D. Katz S. Krieg, T. Lippert +4
We study the finite temperature transition in QCD with two flavors of dynamical fermions at a pseudoscalar pion mass of about 350 MeV. We use lattices with temporal extent of …
Toward fault-tolerant parallel-in-time integration with PFASST
Robert Speck, Daniel Ruprecht
We introduce and analyze different strategies for the parallel-in-time integration method PFASST to recover from hard faults and subsequent data loss. Since PFASST stores solutions…
Lattice computation of the nucleon scalar quark contents at the physical point
S. Durr, Z. Fodor, C. Hoelbling +10
We present a QCD calculation of the , and scalar quark contents of nucleons based on lattice ensembles with dynamical sea quarks, lattice spacings d…
Hierarchical Parallelisation of Functional Renormalisation Group Calculations -- hp-fRG
Daniel Rohe
The functional renormalisation group (fRG) has evolved into a versatile tool in condensed matter theory for studying important aspects of correlated electron systems. Practical app…
QED effects in the pseudoscalar meson sector
R. Horsley, Y. Nakamura, H. Perlt +8
We present results on the pseudoscalar meson masses from a fully dynamical simulation of QCD+QED. We concentrate particularly on violations of isospin symmetry. We calculate the $π…
Axion cosmology, lattice QCD and the dilute instanton gas
S. Borsanyi, M. Dierigl, Z. Fodor +6
Axions are one of the most attractive dark matter candidates. The evolution of their number density in the early universe can be determined by calculating the topological susceptib…
Disconnected contributions to the spin of the nucleon
A. J. Chambers, R. Horsley, Y. Nakamura +8
The spin decomposition of the proton is a long-standing topic of much interest in hadronic physics. Lattice QCD has had much success in calculating the connected contributions to t…
Effects of Boundary Conditions on Single-File Pedestrian Flow
Jun Zhang, Antoine Tordeux, Armin Seyfried
In this paper we investigate effects of boundary conditions on one dimensional pedestrian flow which involves purely longitudinal interactions. Qualitatively, stop-and-go waves are…
Experimental studies of pedestrian flows under different boundary conditions
Jun Zhang, Armin Seyfried
In this article the dynamics of pedestrian streams in four different scenarios are compared empirically to investigate the influence of boundary conditions on it. The Voronoi metho…
Potential description of charmonium and charmed-strange mesons from lattice QCD
Taichi Kawanai, Shoichi Sasaki
We present spin-independent and spin-spin interquark potentials for the charmonium and charmed-strange mesons, which are calculated in 2+1 flavor lattice QCD simulations using the…
Isospin splittings of meson and baryon masses from three-flavor lattice QCD + QED
R. Horsley, Y. Nakamura, H. Perlt +8
Lattice QCD simulations are now reaching a precision where isospin breaking effects become important. Previously, we have developed a program to systematically investigate the patt…
Complex Langevin dynamics for dynamical QCD at nonzero chemical potential: a comparison with multi-parameter reweighting
Z. Fodor, S. D. Katz, D. Sexty +1
We study lattice QCD at non-vanishing chemical potential using the complex Langevin equation. We compare the results with multi-parameter reweighting both from and phase quen…
Finite-temperature charge transport in the one-dimensional Hubbard model
F. Jin, R. Steinigeweg, F. Heidrich-Meisner +2
We study the charge conductivity of the one-dimensional repulsive Hubbard model at finite temperature using the method of dynamical quantum typicality, focusing at half filling. Th…
Screening and plasmons in pure and disordered single- and bilayer black phosphorus
Fengping Jin, Rafael Roldán, Mikhail I. Katsnelson +1
We study collective plasmon excitations and screening of disordered single- and bilayer black phosphorus beyond the low energy continuum approximation. The dynamical polarizability…
Fluctuations and correlations in high temperature QCD
R. Bellwied, S. Borsanyi, Z. Fodor +4
We calculate second- and fourth-order cumulants of conserved charges in a temperature range stretching from the QCD transition region towards the realm of (resummed) perturbation t…
The QCD phase diagram from analytic continuation
R. Bellwied, S. Borsanyi, Z. Fodor +4
We present the crossover line between the quark gluon plasma and the hadron gas phases for small real chemical potentials. First we determine the effect of imaginary values of the…
Steady State of Pedestrian Flow in Bottleneck Experiments
Weichen Liao, Antoine Tordeux, Armin Seyfried +4
Experiments with pedestrians could depend strongly on initial conditions. Comparisons of the results of such experiments require to distinguish carefully between transient state an…

Zoltan Fodor, Kieran Holland, Julius Kuti +3
We compute the renormalized running coupling of SU(3) gauge theory coupled to N_f = 2 flavors of massless Dirac fermions in the 2-index-symmetric (sextet) representation. This mode…
