Journal of High Energy Physics, 2020 Gauge theory is the framework of the Standard Model of particle physics and is also important in condensed matter physics. As its major non-perturbative approach, lattice gauge theory is traditionally implemented using Monte Carlo simulation ...

Monte Carlo Hamiltonian of lattice gauge theory [PDF]
Mod.Phys.Lett.A22:565-572,2007, 2005 We discuss how the concept of the Monte Carlo Hamiltonian can be applied to lattice gauge theories.

Quantization of anomaly coefficients in 6D N=1,0 $$ \mathcal{N}=\left(1,\;0\right) $$ supergravity
Journal of High Energy Physics, 2018 We obtain new constraints on the anomaly coefficients of 6D N=10 $$ \mathcal{N}=\left(1,0\right) $$ supergravity theories using local and global anomaly cancellation conditions.

Higher homotopy and lattice gauge fields [PDF]
arXiv, 2023 We present a general formalism for higher dimensional versions of lattice gauge fields based on higher strict homotopy groupoids. First, using the language of nonabelian Algebraic Topology, we define local lattice higher gauge fields. Then, we provide local-to-global principles for lattice higher gauge fields based on the HHSvK theorem.

Lattice quantum electrodynamics in (3+1)-dimensions at finite density with tensor networks
Nature Communications, 2021 Tensor network simulations of lattice gauge theories may overcome the limitations of the Monte Carlo approach, but results have been limited to 1+1 and 2+1 dimensions so far.

Improving lattice perturbation theory [PDF]
Phys.Rev. D53 (1996) 2605-2609, 1995 Lepage and Mackenzie have shown that tadpole renormalization and systematic improvement of lattice perturbation theory can lead to much improved numerical results in lattice gauge theory. It is shown that lattice perturbation theory using the Cayley parametrization of unitary matrices gives a simple analytical approach to tadpole renormalization, and ...

Elasticity of Diametrically Compressed Microfabricated Woodpile Lattices
Advanced Engineering Materials, EarlyView.Modulus–porosity relationship is derived for woodpile lattices with struts under diametrical compression. The formula presented here that Young's modulus is proportional to the square of the volume fraction E˜ρ2$E \sim \left(\rho\right)^{2}$ is shown to be consistent with computations and laboratory experiments on 3D‐printed samples.

Chiral gauge theories on the lattice and restoration of gauge symmetry [PDF]
Nucl.Phys.Proc.Suppl. 34 (1994) 605-607, 1993 We investigate a proposal for the construction of models with chiral fermions on the lattice using staggered fermions. In this approach the gauge invariance is broken by the coupling of the staggered fermions to the gauge fields. We aim at a dynamical restoration of the gauge invariance in the full quantum model.

Advanced Engineering Materials, EarlyView.A metallic implant's higher stiffness compared to the surrounding bone leads to stress shielding problems, causing bone density reduction and bone growth interference in pediatric patients. 3D‐printed triply periodic minimal surface structures present a promising engineering solution.

Mechanisms of De‐icing by Surface Rayleigh and Plate Lamb Acoustic Waves
Advanced Engineering Materials, EarlyView.Ice accretion impacts daily life, renewable energy generation, maintenance, and security in industries and aeronautics. Acoustic waves (AW) are a promising method for ice removal, although de‐icing mechanisms require further investigation to optimize energy efficiency.
