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 constructs and analyzes charged AdS black hole solutions in 4D Einstein-Gauss-Bonnet gravity coupled to Euler-Heisenberg nonlinear electrodynamics, demonstrating how higher-curvature and nonlinear electromagnetic corrections significantly alter horizon structures, thermodynamic phase transitions, Joule-Thomson expansion, and particle dynamics.
This paper employs the high-precision Spectral Method to analyze the quasinormal modes of Planck stars within a scale-dependent gravity framework, revealing a complex oscillatory spectrum with unique features like Martini glass morphology and isolated overdamped modes that were previously undetected by lower-order approximation techniques.
This paper introduces a new algorithm for symbolic syzygy-constrained IBP reduction of Feynman integrals that bypasses large intermediate equation systems to achieve faster processing of high-power numerators, and presents LoopIn, a modular framework for automating multi-loop calculations.
This paper computes the low-energy expansion of one-loop five-point massless type IIB superstring amplitudes across all charge sectors, deriving moduli-dependent effective action couplings up to specific derivative orders that satisfy -duality constraints and reveal a rich arithmetic structure involving single-valued multiple zeta values and novel constants.
This paper proposes a new modified cosmological model derived from a generalized entropy with non-separable microstate scaling, which introduces an effective dark energy sector capable of exhibiting quintessence-like, phantom-like, or crossing behaviors that ultimately stabilize to a cosmological constant while preserving the standard thermal history of the Universe.
This paper investigates how local physics emerges in perturbative quantum gravity on de Sitter space by constructing gauge-invariant relational observables that approximate local field algebras, revealing that while this approximation is limited near minimal spheres to logarithmic time intervals, it remains valid over arbitrarily large regions in the far future or past, including entire static patches.
This paper introduces a new algorithm for the efficient integration-by-parts (IBP) reduction of complex Feynman integrals with high powers of numerators or propagators, utilizing syzygy-constrained symbolic rules and small linear systems to achieve significantly faster computation speeds in demanding applications like multi-loop scattering amplitudes and spinning black hole binary systems.
This paper provides a pedagogical review of projective representations and the Bogomolov multiplier while presenting new physical results that link these mathematical concepts to undetectable (1+1)D SPT phases and distinct gapped phases with broken non-invertible symmetries, demonstrated through explicit lattice models and interface mode analysis.
This paper proposes that cosmological tensions regarding the expansion history and CMB lensing can be resolved by interpreting them as evidence for a negative neutrino mass, which can be realized through new light fields or dark sector models that predict distinct observable signals in polarization and galaxy statistics.
This paper investigates the construction of a Nicolai map for minimal four-dimensional supergravity, identifying significant obstructions from local supersymmetry and the conformal factor while successfully deriving a four-parameter first-order map, though full verification requires further second-order and quantum-level analysis.
