hep-lat papers | Gist.Science

Hep-Lat, short for High Energy Physics – Lattice, explores the fundamental forces of nature by simulating particle interactions on a digital grid. Instead of relying solely on abstract equations, researchers in this field use powerful computers to model how quarks and gluons bind together, offering deep insights into the structure of matter that are often impossible to derive analytically.

Gist.Science ensures these complex discoveries from arXiv remain accessible to everyone. We process every new preprint in this category as it is posted, providing both plain-language explanations for the curious and detailed technical summaries for experts. This dual approach bridges the gap between cutting-edge simulation work and broader scientific understanding.

Below are the latest papers in High Energy Physics – Lattice, curated directly from arXiv and ready for you to explore.

Automatic Structural Search of Tensor Network States including Entanglement Renormalization

This study presents an algorithm for the automatic structural search of tensor network states, including entanglement renormalization, which optimizes local structures based on variational energy to improve accuracy in representing non-uniform entangled states, particularly when initialized with existing design methods like the strong disordered renormalization group.

$I=\frac{3}{2}$ $πK$ $s$ -wave scattering length from lattice QCD

Using lattice QCD with physical quark masses and Asqtad-improved staggered fermions, this study computes the $I=\frac{3}{2}$ $\pi K$ $s$ -wave scattering length and effective range parameters, finding results that align with both next-to-leading order chiral perturbation theory predictions and experimental measurements.

Reducing the Computational Cost Scaling of Tensor Network Algorithms via Field-Programmable Gate Array Parallelism

This paper proposes a fine-grained parallel tensor network design utilizing FPGAs and a quad-tile partitioning strategy to drastically reduce the computational cost scaling of iTEBD and HOTRG algorithms from $O(D_b^3)$ to $O(D_b)$ and from $O(D_b^6)$ to $O(D_b^2)$ , respectively, thereby offering a scalable hardware solution for large-scale quantum many-body calculations.

Spontaneous Parity Breaking in Quantum Antiferromagnets on the Triangular Lattice

This paper demonstrates that spontaneous parity breaking serves as a systematic guiding principle for predicting and rationalizing the emergence of nontrivial phases, such as intermediate-spin parity-broken states and bilayer supersolids, in frustrated quantum antiferromagnets on triangular lattices, a conclusion validated by large-scale tensor network calculations.

Numerical stability of force-gradient integrators and their Hessian-free variants in lattice QCD simulations

This paper demonstrates through linear stability analysis and lattice QCD simulations that Hessian-free variants of force-gradient integrators offer comparable stability to conventional methods while enabling more efficient computations for interacting field theories.

Strong CP and the QCD Axion: Lecture Notes via Effective Field Theory

These lecture notes provide a graduate-level introduction to the strong CP problem and QCD axion physics from an effective field theory perspective, covering the construction of chiral EFT, the derivation of CP-odd observables, generalizations to various gauge theories, critiques of alternative solutions, and the standard Peccei-Quinn mechanism.

Resurrecting the coherent state variational algorithm for large $N$ gauge theories

This paper reassesses the feasibility of using coherent state variational methods for large $N$ gauge theories by introducing a new implementation applicable to SU( $N$ ) lattice gauge theories with or without fermions, and presents initial results for Hamiltonian Yang-Mills theory on an infinite two-dimensional spatial lattice.

Probing Instanton Dynamics in the Pion Vector Form Factor with Wilson Flow

This paper proposes using Wilson flow on lattice QCD configurations to isolate instanton contributions and study the pion electromagnetic form factor, aiming to validate the precision of the instanton liquid model against non-perturbative simulations.

On the moduli space of multi-fractional instantons on the twisted $\mathbb T^4$

This paper investigates the moduli space of multi-fractional instantons on a twisted $\mathbb{T}^4$ by demonstrating that 't Hooft's constant field strength solutions constitute the entire moduli space only when $\gcd(k,r)=r$ , whereas for $\gcd(k,r)\neq r$ , they represent a measure-zero subset surrounded by non-constant, non-abelian solutions, a finding that resolves a recent puzzle and is validated through analytical, numerical, and lattice comparisons.

Prediction for Maximum Supercooling in SU(N) Confinement Transition

This paper predicts that the maximum achievable supercooling in $SU(N)$ confinement transitions is limited to a few percent due to a deconfined phase instability just below the critical temperature, a finding derived from softly-broken SUSY insights that implies a significant suppression of associated cosmological gravitational wave signals.
