A Variational Beam Model for Failure of Cellular and Truss‐Based Architected Materials
Advanced Engineering Materials, EarlyView., 2023 Herein, a versatile and efficient beam modeling framework is developed to predict the nonlinear response and failure of cellular, truss‐based, and woven architected materials. It enables the exploration of their design space and the optimization of their mechanical behavior in the nonlinear regime. A variational formulation of a beam model is presented

Charge completeness and the massless charge lattice in F-theory models of supergravity
Journal of High Energy Physics, 2021 We prove that, for every 6D supergravity theory that has an F-theory description, the property of charge completeness for the connected component of the gauge group (meaning that all charges in the corresponding charge lattice are realized by massive or ...

Abelian monopole condensation in lattice gauge theories [PDF]
Nucl.Phys.Proc.Suppl. 83 (2000) 428-430, 1999 We investigate the dynamics of lattice gauge theories in an Abelian monopole background field. By means of the gauge-invariant lattice Schrodinger functional we study the Abelian monopole condensation in U(1) lattice gauge theory at zero temperature and in SU(3) lattice gauge theory at finite temperature.

The lowest Landau level in QCD
EPJ Web of Conferences, 2017 The thermodynamics of Quantum Chromodynamics (QCD) in external (electro-)magnetic fields shows some unexpected features like inverse magnetic catalysis, which have been revealed mainly through lattice studies.

Quantum sampling for the Euclidean path integral of lattice gauge theory [PDF]
Phys. Rev. D 105, 094501 (2022), 2022 Although the Hamiltonian formalism is so far favored for quantum computation of lattice gauge theory, the path integral formalism would never be useless. The advantages of the path integral formalism are the knowledge and experience accumulated by classical lattice simulation and manifest Lorentz invariance.

Digital quantum simulation of lattice gauge theories in three spatial dimensions
New Journal of Physics, 2018 In the present work, we propose a scheme for the digital formulation of lattice gauge theories with dynamical fermions in 3 + 1 dimensions. All interactions are obtained as a stroboscopic sequence of two-body interactions with an auxiliary system.

Semi-Abelian gauge theories, non-invertible symmetries, and string tensions beyond N-ality
Journal of High Energy Physics, 2021 We study a 3d lattice gauge theory with gauge group U(1) N−1 ⋊ S N , which is obtained by gauging the S N global symmetry of a pure U(1) N−1 gauge theory, and we call it the semi-Abelian gauge theory.

Lattice Chiral Gauge Theories in a Renormalizable Gauge [PDF]
Nucl.Phys.Proc.Suppl. 53 (1997) 664-667, 1996 The lattice formulation of gauge theories in a renormalizable gauge is discussed. The formulation invokes a new phase diagram, and it may allow for a lattice definition of Chiral Gauge Theories.

Almost Gauge Invariant Lattice Actions for Chiral Gauge Theories, using Laplacian Gauge Fixing [PDF]
Phys.Lett. B321 (1994) 239-245, 1993 It is described how to obtain an almost gauge invariant lattice action $S$ for chiral gauge theories, or other models in which a straightforward discretization leads to a lattice action $S^\pr$ in which gauge invariance is broken. The lattice action is `almost' gauge invariant, because a local gauge transformation leaves the action the same, up to a ...
