The authors propose and demonstrate the axial anomaly as a robust benchmark for quantum computing by successfully simulating anomalous axial-charge production in lattice gauge theories on the "Reimei" trapped-ion quantum computer, reproducing the exact anomaly coefficient within statistical uncertainties without error mitigation.
This paper demonstrates that a lattice gauge theory on a multi-graph with an odd number of links exhibits symmetry-protected topological order and charge deconfinement via fractionalized solitons, driven by a Peierls-like instability that intertwines gauge flux ordering with bond order waves.
This paper introduces a new universality paradigm for hybrid qubit-qumode quantum computing based on trigonometric continuous-variable gates, demonstrating their effectiveness through a deterministic ancilla-based implementation and a successful simulation of the lattice sine-Gordon model, including ground state preparation, real-time dynamics, and kink profile extraction.
This paper proposes a "field digitization scaling" framework that treats the number of discrete field values as a renormalization group coupling, successfully applying it to relate the 2D classical clock model to the XY model and its quantum gauge theory counterpart to enable continuum limit analysis in quantum simulations.
Using a coupled-channels framework derived from a constituent quark model, this study predicts a rich spectrum of resonant and virtual tetraquark candidates exhibiting heavy-quark spin symmetry multiplets, with specific guidance provided for their experimental detection through characteristic decay patterns and widths.
This paper introduces Constrained Symplectic Quantization, a holomorphic reformulation of symplectic quantization that imposes constraints on intrinsic time Hamiltonian flow to resolve structural limitations and establish exact equivalence with the Feynman path integral, thereby enabling the accurate numerical sampling of real-time quantum observables as demonstrated on the quantum harmonic oscillator.
This paper presents updated lattice results on the intrinsic width of the flux tube in (2+1)-dimensional SU(2) Yang-Mills theory, demonstrating a constant value at low temperatures consistent with the Clem model and a growing trend near the deconfinement transition that aligns with Svetitsky-Yaffe mapping predictions.
The Extended Twisted Mass Collaboration presents an updated determination of the leading-order hadronic vacuum polarisation contribution to the muon anomalous magnetic moment in isospin-symmetric QCD, utilizing five gauge ensembles with near-physical pion masses and employing two distinct valence-quark regularisations to calculate both isovector and isoscalar components.
This paper demonstrates that the Serreau–Tissier replica sector in Yang–Mills theories can dynamically generate a Gribov–Zwanziger-type horizon functional through the expansion of the Faddeev–Popov determinant, thereby providing a microscopic mechanism for the emergence of the Gribov scale that yields either a Curci–Ferrari mass or a refined Gribov–Zwanziger decoupling propagator depending on the replica symmetry phase.
This paper reviews how recent advancements in Large Momentum Effective Theory (LaMET), including improved renormalization schemes, higher-order matching kernels, and novel lattice operators, are enhancing the precision and reliability of first-principles lattice QCD calculations for proton parton distributions.
This paper defends Large-Momentum Effective Theory (LaMET) against recent claims that it suffers from an unquantifiable inverse problem, arguing that physics-guided systematic extrapolation remains the most reliable method for estimating uncertainties in parton distribution calculations even when lattice data precision is suboptimal.
This review examines the fundamental principles of thermal field theory in a background magnetic field, focusing on equilibrium systems to analyze bulk thermodynamic properties and real-time observables relevant to the thermo-magnetic QCD plasma in heavy-ion collisions.

This paper demonstrates that the two-dimensional Rokhsar-Kivelson lattice gauge model intrinsically hosts exact stabilizer eigenstates known as sublattice scars, establishing a direct link between lattice gauge constraints, quantum many-body scarring, and stabilizer quantum information theory.
Addressing the breakdown of Bloch's theorem in spatially varying composites, this paper establishes a foundational ab initio quantum theoretical framework for functionally graded materials that derives effective field equations for modulated Bloch states, revealing non-tensorial electromagnetic properties and enabling the predictive design of optimized electronic devices such as graded p-n junctions.
This study utilizes lattice QCD simulations to analyze the Dirac eigenspectrum at finite temperature, revealing how intermediate level statistics and Thouless conductance serve as diagnostics for the interplay between chiral symmetry restoration and disorder-driven localization, particularly in the context of the effective restoration of the anomalous symmetry.

This paper demonstrates that by renormalizing the Dirac field in curved spacetime, the metric's temporal and spatial gradients naturally induce non-Hermitian phenomena—specifically nonunitary gain/loss and the non-Hermitian skin effect—thereby establishing a unified geometric framework that links spacetime deformations to non-Hermitian phases of matter.
