Summary: The YM theory has been generalized to 2YM and 3YM theories, and similarly, the BFYM theory has been generalized to 2BFYM and 3BFYM theories. It is shown that these higher BFYM theories can provide formulations for the corresponding higher form YM theories. Additionally, the gauge symmetries of these higher BFYM theories are also studied.

Summary: This study extends the investigation of transverse Ward-Fradkin-Green-Takahashi identities in QED to the equivalent gauge identities in QCD, revealing the constraints on the transverse quark-gluon vertex and deriving its associated scalar form factors. By studying the functional form of these form factors, significant chiral symmetry breaking and a mass gap in the quark are observed, leading to interesting implications such as the quark condensate and the pion's weak decay constant in the chiral limit.

Summary: A formalism was proposed to extract the gamma pi -> pi pi chiral anomaly F-3 pi from lattice QCD calculations performed at larger-than-physical pion masses. By combining dispersion relations and effective field theory, recent lattice QCD calculations for gamma pi -> pi pi were extrapolated to the physical point, allowing the extraction of the radiative coupling of the rho(770) meson and the chiral anomaly F-3 pi = 38(16)(11) GeV-3 for the first time. The result is consistent with chiral predictions but has large uncertainties that may improve with future lattice-QCD computations.

Summary: This paper provides a proof of the gauge invariance of the measure associated with the gauge field, and highlights the importance of this fact by showing the effective cancellation of gauge anomalies. Through path integral arguments and direct calculations, it is demonstrated that the Jacobian for gauge transformations must be the identity operator in the physical Hilbert space.

Summary: In this paper, an improved regularization-independent (RI)-type prescription is presented for the nonperturbative renormalization of gauge-invariant nonlocal operators. This method involves subtracting finite lattice spacing effects calculated in lattice perturbation theory to improve the nonperturbative vertex function. The approach is versatile, applicable to various fermion and gluon actions, and different types of nonlocal operators.

Summary: We study lattice fermions using spectral graph theory (SGT). We find that a fermion on a lattice can be understood as a spectral graph. SGT helps in determining the number of fermion species on lattices with arbitrary topologies by investigating the zero eigenvalues of lattice Dirac operators. We apply the procedure of SGT to various lattice fermion formulations and reproduce the known results on the number of species.

Summary: This study proposes to use noisy-intermediate-scale-quantum-era quantum devices to compute short distance quantities in (2 + 1)-dimensional QED, and combine them with large volume Monte Carlo simulations and perturbation theory. By performing quantum computations, the mass gap in the small and intermediate regime can be reliably resolved and matched with corresponding results from Monte Carlo simulations.

Summary: The article introduces the lattice compact Abelian Higgs model and quantum simulation using a ladder-shaped optical lattice in 1 + 1 dimensions. By building local Hilbert spaces with Rydberg atoms, the concept of ladder-shaped configurable arrays is proposed. Concrete proposals involving two and three atoms for constructing spin-1 spaces and analytical tools for design and building are discussed.

Summary: This article presents the first calculation of the scattering amplitude in the singlet channel beyond QCD. The calculation is performed in SU(2) gauge theory with N-f=2 fundamental Dirac fermions and based on a finite-volume scattering formalism. The theory exhibits a SU(4)->Sp(4) chiral symmetry breaking pattern that is used to design minimal composite Higgs models currently tested at the LHC. Our results show that, for the range of underlying fermion mass considered, the lowest flavor singlet state is stable.

Summary: In this paper, we propose a method of inverse renormalization group transformations within the context of quantum field theory. This method can produce the appropriate critical fixed point structure, avoid the critical slowing down effect, and extract critical exponents. We also discuss the general applicability of this method and its insights into the structure of the renormalization group.

Summary: This project aims to use data from the Fermi Gamma-ray Space Telescope to train a machine-learning model that can accurately predict the redshift of active galactic nuclei (AGNs). By implementing feature engineering, bias correction techniques, and other ML methods, a catalog of estimated redshift values can be provided for AGNs without spectroscopic redshift measurements.

Summary: In this study, we investigate the confinement/deconfinement transition in the DO-brane matrix model and its deformation numerically through lattice Monte Carlo simulations. Our findings confirm the general expectations from the dual string/M-theory picture for strong coupling. Furthermore, we suggest that these models offer an ideal framework for studying the Schwarzschild black hole, M-theory, and the parameter region of the phase transition between type IIA superstring theory and M-theory. Additionally, a detailed study of M-theory using lattice Monte Carlo simulations of the DO-brane matrix model may be feasible with smaller computational resources than previously anticipated.

Summary: We propose a universal rescaling method for the ratio between topological susceptibility and string tension squared in four-dimensional Yang-Mills theories, which depends only on group factors. We apply this method to SU(N-c) and Sp(N-c) groups and compare lattice measurements from different independent collaborations. The results show that the numerical sequences in these two groups are compatible with each other, and we perform a combined fit and extrapolate to the large-N-c limit.

Summary: We test the gauge/gravity duality between the matrix model and type IIA string theory at low temperatures with unprecedented accuracy. By performing lattice Monte Carlo simulations of the BMN matrix model, we demonstrate the perfect agreement of energy with supergravity predictions, including alpha'-corrections, at the lowest temperature to date, and we obtain the coefficient of the 1/N-4 corrections with good accuracy at a fixed temperature.

Summary: We study the partially-deconfined saddle in large-N pure Yang-Mills theory, which lies between the confined and deconfined phases and splits the color degrees of freedom into confined and deconfined sectors. By analyzing the mechanism of deconfinement, we propose the formation of a flux tube and the generation of a linear confinement potential in the confined sector. We provide evidence for this conjecture through analytic predictions and numerical simulations in the case of finite-temperature strong-coupling lattice gauge theory, and discuss its implications in QCD and holography.

Summary: This article reviews the current status of the long-term numerical investigation programme of Sp(2N) gauge theories with and without fermionic matter content. The motivations for this research programme, related to composite Higgs models, partial top compositeness models, dark matter models, and strongly coupled theories, are introduced. The results of lattice studies in the Sp(2N) Yang-Mills theories, including the measurements of string tension, mass spectrum of glueballs, and topological susceptibility, are summarized. The measurements of mass and decay constant of mesons in the Sp(4) theories with fermion matter in different representations are discussed, along with the case of dynamical fermions in mixed representations and exotic composite fermion states.

Summary: Gamma-ray bursts (GRBs) are crucial for cosmological studies and investigating Population III stars. However, gaps in the light curves hinder the precise determination of GRB properties and categorization. Researchers address this issue by using stochastic reconstruction and Gaussian processes to fill in the gaps and decrease uncertainty, which is essential for the application of GRBs in cosmology and theoretical models.

Summary: Autonomous quantum error correction (AQEC) protects logical qubits by engineered dissipation, and a promising candidate for AQEC is bosonic code spaces. We propose a bosonic code for approximate AQEC by relaxing the Knill-Laflamme conditions, using reinforcement learning (RL) to identify the optimal bosonic set of code words. The RL code successfully suppresses single-photon loss, surpassing the break-even threshold and providing a valuable building block towards full error protection.

Summary: We study the use of persistent homology as a tool to detect and describe center vortices in the SU(2) lattice gauge theory. We show evidence of the sensitivity of our method by detecting explicitly inserted vortices using twisted boundary conditions. We propose a new phase indicator for the deconfinement phase transition and construct another indicator without reference to twisted boundary conditions. Finite-size scaling analyses of both indicators provide accurate estimates of the critical beta and critical exponent of the deconfinement phase transition.

Summary: The sparse version of the Sachdev-Ye-Kitaev model reduces the number of disorder parameters while reproducing essential features of the original model. In this Research Letter, a further simplification called the binary-coupling sparse SYK model is proposed. This model sets the nonzero couplings to be +/- 1 instead of sampling from a continuous distribution. Remarkably, this simplification improves the model's performance in terms of exhibiting strong correlations in the spectrum and efficiently achieving random-matrix universality with fewer nonzero terms. Due to its simplicity and scaling properties, this model is better suited for quantum simulations of chaotic behavior and holographic metals.

Summary: Matrix quantum mechanics plays crucial roles in theoretical physics, such as providing a holographic description of quantum black holes and supporting the study of complex high-dimensional supergravity theories. Quantum computing and deep learning could potentially become valuable tools for understanding the dynamics of matrix quantum mechanics and could potentially lead to new discoveries in quantum gravity research.
