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 investigates the analytic structure of finite-temperature two-point functions in the large- SYK model by tracking complex-time singularities that persist to zero temperature, revealing how the leading singularity defines an effective temperature for operator complexity while the next-to-leading singularity suggests a connection to bouncing null geodesics in an emergent black hole geometry.
This paper introduces a Kontorovich-Lebedev-Fourier (KLF) space formalism that replaces nested time integrals with frequency integrals over rational propagators to compute tree-level cosmological correlators, demonstrating the method's efficacy through a complete analytical treatment of the double-exchange diagram expressed as a double series of hypergeometric functions.
This paper argues that analytically continuing Quantum Field Theories like QCD and QED to non-integer dimensions is problematic because these theories exhibit branch cuts in the complex dimension plane, causing operator scaling dimensions and OPEs to jump discontinuously rather than varying smoothly.
This paper resolves the incompatibility between two gauge-invariant accounts of the Abelian Higgs mechanism by demonstrating, through constrained Hamiltonian formalism and -algebraic analysis, that the mechanism involves the spontaneous breaking of physical global symmetry (which persists under boundary conditions) rather than local gauge symmetry, thereby establishing the Coulomb gauge as the preferred framework for a consistent gauge-invariant description.
This paper introduces a new solution-generating technique to derive the first exact nonstationary, axisymmetric solution for a compact object in a FLRW cosmology and outlines a method using the mean curvature vector to analyze its dynamical trapping horizons and causal structure.
This paper generalizes the Bern-Carrasco-Johansson double-copy principle by enforcing color-kinematics duality on a complete basis of four-point color structures, thereby demonstrating that all parity-even four-graviton amplitudes in any dimension can be systematically constructed from gauge-theory building blocks, with the exception of the Lovelock term in which requires a universal triple-copy.
This paper proposes that a transient violation of the null energy condition during inflation generates primordial black holes and a distinctive, multi-component stochastic gravitational wave background—encompassing primordial, scalar-induced, ringdown, and binary merger signals—that can be probed through future multi-band observations to constrain inflationary physics.
This paper proposes a cosmological model satisfying the Covariant Entropy Bound where early-universe tiny black holes decay to generate the radiation-dominated era and CMB observations, while a distribution of larger primordial black holes and their Planck-scale remnants account for dark matter and the formation of early galaxies observed by the James Webb Space Telescope.
This review article introduces the fuzzy sphere regularization method as an efficient tool for studying 3D conformal field theories and critical phenomena, highlighting its unique ability to reveal deep connections between noncommutative geometry, the quantum Hall effect, and the state-operator correspondence on the geometry.
This paper employs the worldline formalism and geometric quantization to construct a Hilbert space of Virasoro conformal blocks for matter coupled to 3D Einstein gravity, successfully reproducing the known one-loop partition function on thermal AdS and conjecturing its all-orders value via equivariant localization.
