Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.
At Gist.Science, we monitor the arXiv repository to ensure you stay ahead of the curve in this rapidly evolving discipline. For every new preprint uploaded to arXiv under this category, our team generates both accessible plain-language overviews and detailed technical summaries, making cutting-edge research understandable regardless of your background.
Below are the latest papers in high-energy theoretical physics, curated to help you navigate the most significant recent discoveries.
This paper argues that the Kerr-Schild and twistorial double copy prescriptions are equivalent for a broad class of self-dual vacuum solutions, a claim demonstrated through elementary null Lorentz transformations and illustrated with the self-dual Kerr-Taub-NUT spacetime.
This paper develops theoretical diagnostics for the breakdown of mean-field theory, demonstrating how spatial structure and finite interaction ranges qualitatively alter the effective description and renormalization-group flow.
This paper establishes strict quantitative conditions and demonstrates via simulation that a mesoscopic spinor Bose-Einstein condensate of approximately 370 spins near the Lipkin-Meshkov-Glick critical point can exhibit classically forbidden temporal correlations, specifically through an exponentially suppressed Landau-Zener error rate and a Leggett-Garg inequality violation (K_3 ~ 1.32), both robust against realistic dephasing due to emergent collective symmetry and dynamical phase alignment.
This paper introduces `fermionic_amplitudes.m`, a Mathematica package that computes tree-level scattering amplitudes for arbitrary numbers of gauge bosons and massless fermions in pure non-supersymmetric gauge theories by expressing distinct-flavour amplitudes as linear combinations of single-flavour components derived from supersymmetric Yang-Mills theory, while providing explicit numeric colour tensors for cross-section calculations.
This paper proposes that simple neural networks trained on crossing symmetry can accurately reconstruct conformal correlators using minimal inputs, a success attributed to the alignment between the spectral bias of gradient-based training and the intrinsic smoothness of conformal field theory, thereby suggesting a novel variational principle for non-perturbative quantum field theory.
This paper derives the all-order fluctuating hydrodynamics of the SYK lattice from its microscopic nonlinear action, explicitly embedding hydrodynamic degrees of freedom into the model and determining all corresponding transport coefficients to demonstrate how hydrodynamics emerges from a strongly coupled quantum many-body system.
This paper demonstrates that simple feed-forward neural networks can accurately reconstruct diverse conformal field theory correlators using minimal data—specifically crossing symmetry, a single scaling dimension, and one anchor point—by leveraging the spectral bias of gradient-based training to favor the smooth functions characteristic of physical correlators.
This paper analyzes the stability of tachyon-free non-supersymmetric heterotic string flux compactifications on , revealing that while perturbative tachyons can be avoided or projected out depending on flux separation, the system remains universally unstable to non-perturbative brane nucleation that drives the fluxes toward a tachyonic regime.
This paper provides holographic consistency checks for a conjectured supersymmetric gauge theory that flows from a conformal UV to gapped IR vacua by demonstrating an area law for Wilson loops, constructing domain walls governed by Yang-Mills-Chern-Simons theory that reproduce the correct anomaly inflow, and showing the instability of axionic strings which confirms the absence of a massless axion.
This paper utilizes exact diagonalization and matrix product state techniques on a fuzzy sphere to extract conformal data for the -dimensional Wilson-Fisher CFT, identifying 32 primary operators and verifying their scaling dimensions against conformal bootstrap predictions and large charge expansion results.
