A first look at Structured-Multiscale Algebraic Multigrid for Lattice Field Theory
Pauline Schauerte, Jaime Fabián Nieto Castellanos, Arnold Krechel +2
State-of-the-art solvers for the Dirac equation in Lattice QCD are based on adaptive multigrid methods. These require fine-tuning of many algorithmic parameters to achieve optimal…
Future Requirements of Lattice Field Theory Calculations on European High-Performance Computing Facilities
Gert Aarts, Gunnar Bali, Jacob Finkenrath +4
Lattice field theory provides a first-principles framework for studying properties of strongly interacting quantum field theories in elementary particle physics. Researchers in lat…
Exclusion of a diquark-antidiquark structure for the lightest positive-parity charmed mesons
Eric B. Gregory, Feng-Kun Guo, Christoph Hanhart +2
The nature of low-lying scalar and axial-vector charmed mesons has been debated for decades, with hadronic molecular and compact tetraquark models being prominent candidates. These…
Exotics in the system
Eric B. Gregory, Feng-Kun Guo, Christoph Hanhart +2
In this proceedings we consider several states, namely the , , and , which appear to defy description as simple quark-ant…
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…
