This paper presents an efficient implementation of the Quantum Minimally Entangled Typical Thermal States (QMETTS) algorithm for gauge theories at finite temperature and density, featuring derived measurement bases to preserve gauge invariance, a noise-robust sampling method for expectation values, and numerical validation on a (1+1)-dimensional model.
This paper applies a Pauli-Villars regulated photon propagator defined in continuum infinite volume to lattice QCD calculations on CLS ensembles to determine the electromagnetic pion mass splitting, thereby avoiding power-law finite-size effects and enabling direct cross-checks with phenomenology.
This paper expands on previous findings by investigating the topological structure of the entanglement radius in (2+1)D Yang-Mills theory, specifically examining how flux tube entanglement entropy behaves when the entangling region's cross-sectional length is comparable to the flux tube's intrinsic thickness.
This paper presents an infinite-dimensional matrix representation for arbitrary gauge-invariant operators at a trivalent vertex within the loop-string-hadron (LSH) framework for SU(3) lattice Yang-Mills theory, establishing a standalone computational approach that significantly outperforms the traditional Schwinger-boson method and includes a companion code to facilitate Hamiltonian-based quantum chromodynamics calculations.
This paper presents a lattice QCD study of the conjectured H-dibaryon across five flavor channels and nine temperatures, revealing that the 27-plet channel yields the heaviest mass while the channel is the lightest, with binding energy relative to a pair being negative for the singlet, , and channels but positive for the 27-plet and channels.
This paper presents the first systematic lattice QCD study of proton- scattering across multiple pion masses and lattice spacings, yielding scattering parameters and cross sections that agree with experimental data and confirm attractive interactions critical for nuclear theory and neutron star modeling.
This paper employs nonperturbative Hamiltonian theory with two-particle coupled channels to extract physical electric dipole amplitudes from recent lattice QCD data on threshold pion electroproduction, while deriving a new expression for transition amplitudes that depends solely on final-state interactions.
This paper investigates the feasibility of extracting infinite-volume scattering phase shifts on quantum computers using a one-dimensional trapped system model, demonstrating that while the method yields accurate results with two qubits on IBM hardware, it currently fails with three qubits due to gate operation and thermal relaxation errors.
This paper diagnoses performance limitations in Rydberg-ladder gauge simulators by analyzing bitstring measurements from the Aquila platform, revealing that while readout mitigation is effective, residual errors in probability estimation are primarily driven by imperfect state preparation rather than readout noise.
This paper resolves the inability of staggered-fermion discretizations to support topological phases in (2+1)D Hamiltonian lattice QED by demonstrating that Wilson fermions naturally enable nontrivial topological regimes with nonzero Chern numbers, which are characterized through gauge-invariant diagnostics and exact diagonalization to provide a foundation for near-term quantum simulations.
This paper presents a non-perturbative lattice determination of the baryon junction mass in -dimensional Yang--Mills theory using high-precision simulations and Effective String Theory corrections, while also confirming the Svetitsky--Yaffe conjecture by demonstrating that the system's high-temperature behavior aligns with the two-dimensional three-state Potts model near the deconfinement transition.
Using (2+1)-flavor lattice QCD at the physical point, this study calculates the S-wave - interaction potentials via the HAL QCD method, revealing overall attraction in both spin channels that precludes the formation of a dibaryon bound state and highlighting the dominant role of spin-independent forces driven by heavy-hadron chromo-polarizability.
This paper reports on large-scale lattice studies of the Corrigan--Ramond large- limit of Yang-Mills theory, utilizing gradient flows to analyze topological charge properties and discretisation effects, ultimately concluding that current simulations at lattice spacings of 0.08–0.11 fm are subject to approximately 10% discretisation errors.
This paper reformulates the strong coupling expansion of large- QCD as constrained one-dimensional spin chains, demonstrating that while specific subsectors remain integrable, the full system loses integrability due to zigzag symmetry constraints, yet still successfully estimates the roughening transition point.
This chapter reviews the physics of lattice fermions satisfying the Ginsparg-Wilson relation, explains their connection to domain wall fermions, and outlines the methodology for numerical simulations using overlap fermions as part of the "Lattice QCD at 50 years" book.
This paper summarizes the achievements of the MexNICA Collaboration, established in 2016 to coordinate Mexican participation in the MPD-NICA experiment at JINR, highlighting their contributions to the development of the miniBeBe trigger detector and advances in phenomenological and theoretical studies of the baryon-rich QCD phase diagram.
This paper introduces a generative framework based on denoising diffusion to perform model-independent, non-parametric reconstruction of proton gravitational form factors from sparse and noisy data, enabling robust extraction of chiral low-energy constants and the nucleon D-term across the full kinematic range.

This paper demonstrates that while staggered fermions fail to capture (2+1)D topological phases in lattice QED, Wilson fermions successfully enable the realization of diverse topological states like Chern insulators and quantum spin Hall phases, thereby resolving ambiguities in Hamiltonian formulations and providing a theoretical foundation for future quantum simulations on near-term quantum computing platforms.
This paper establishes universal principles and practical frameworks for simulating non-Abelian gauge theories on quantum computers by demonstrating that both gauge-singlet and non-singlet representations are valid, offering efficient circuit constructions, error analyses, and resource estimates for real-world QCD applications.
