Lattice QCD with open boundary conditions and twisted-mass reweighting [PDF]
, 2012 Lattice QCD simulations at small lattice spacings and quark masses close to their physical values are technically challenging. In particular, the simulations can get trapped in the topological charge sectors of field space or may run into instabilities ...

Time windows of the muon HVP from twisted-mass lattice QCD [PDF]
, 2022 We present a lattice determination of the leading-order hadronic vacuum polarization (HVP) contribution to the muon anomalous magnetic moment, aHVPμ , in the so-called short and intermediate time-distance windows, aSDμ and aWμ .

Deflation acceleration of lattice QCD simulations [PDF]
, 2007 Close to the chiral limit, many calculations in numerical lattice QCD can potentially be accelerated using low-mode deflation techniques. In this paper it is shown that the recently introduced domain-decomposed deflation subspaces can be propagated along

Recent Progress in Nuclear Lattice Simulations
Frontiers in Physics, 2020 We review several recent results on lattice simulations by the Nuclear Lattice Effective Field Theory Collaboration. In the first part we discuss the implementation of nuclear forces on the lattice using chiral effective field theory. The new development

Bulk diffusivity of lattice gases close to criticality [PDF]
, 2017 We consider lattice gases where particles jump at random times constrained by hard-core exclusion (simple exclusion process with speed change). The conventional theory of critical slowing down predicts that close to a critical point the bulk diffusivity ...

A comparative study of deconvolution techniques for quantum-gas microscope images
New Journal of Physics, 2023 Quantum-gas microscopes are used to study ultracold atoms in optical lattices at the single-particle level. In these systems atoms are localised on lattice sites with separations close to or below the diffraction limit.

A symmetric-difference-closed orthomodular lattice that is stateless
Order, 2022 Abstract This paper carries on the investigation of the orthomodular lattices that are endowed with a symmetric difference. Let us call them ODLs. Note that the ODLs may have a certain bearing on “quantum logics”-the ODLs are close to Boolean algebras though they capture the phenomenon of non-compatibility.

Novel Lattice-Searching Method for Modeling the Optimal Strain-Free Close-Packed Isomers of Clusters [PDF]
, 2016 Small icosahedral, decahedral, and fcc structures have been studied by unbiased global optimization methods or Wulff construction and Northby lattice methods.

Advection–Diffusion Lattice Boltzmann Method With and Without Dynamical Filter
Frontiers in Physics, 2022 In multi-component flow and/or thermal flows, when the diffusion coefficient of the advection–diffusion equation is relatively small, the relaxation coefficient in the lattice Boltzmann method will be close to 0.5, which will lead to numerical ...
