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 demonstrates that incorporating fractional memory effects and angular dynamics into the study of cosmic string loops in an expanding universe reveals a class of stable, expanding solutions and chaotic behavior that contrasts with the standard collapse scenario.
This article demonstrates that extending the standard model of cosmology with self-interacting dark radiation and a running spectral index function during inflation significantly relaxes constraints on additional relativistic degrees of freedom and reduces the Hubble tension to below 2 when confronted with data from ACT DR6, Planck, DESI DR2, and Pantheon+.
This paper investigates the integrability of a spinning scalar probe in a root-Kerr background, demonstrating that while the Newman-Janis shift preserves integrability to all spin orders at leading charge interaction, integrability breaks down at the spin-cubic order for second-order charge interactions and cannot be restored by further action deformations.
This paper demonstrates that in two-dimensional evaporating black hole models, increasing the black hole scrambling time suppresses and eventually eliminates late-time entanglement revival spikes in mutual information, marking a smooth transition from quasiparticle-like behavior to maximal scrambling.
This paper demonstrates that the mathematical constant emerges from equatorial quantum localization on a sphere via a geometric rigidity index that yields exact Wallis partial products for finite quantum numbers and converges to the classical Wallis formula in the semiclassical limit.
This paper utilizes the heat kernel formalism and analytic continuation from a product of spheres to derive two-point correlation functions for heavy scalar fields in Nariai geometry, revealing that the result requires a sum over complex geodesics where careful phase management is essential to prevent spurious singularities.
This article presents the first fully gauge-invariant, relativistic calculation of the second-order cosmological redshift drift using light-cone coordinates, according to which the distortion in redshift space is a second-order effect, and shows that the nonlinearities in the bispectrum are significantly enhanced compared to the squared power spectrum at low redshifts and large momenta.
This paper proposes the first examples of scale-separated vacua with extended supersymmetry by constructing circle compactifications of massive type IIA supergravity solutions, providing their ten-dimensional and three-dimensional effective descriptions, and noting that one model's superpotential was uniquely identified with the aid of AI.
This paper introduces equivariant localization as a method to compute the action of supersymmetric probe D3-branes in type IIB backgrounds derived from Kerr-Newman-AdS black holes, enabling the evaluation of non-perturbative corrections and defect operator insertions in 4D quiver SCFTs entirely from toric data.
This paper presents a positive definite formulation for calculating vacuum decay tunneling actions in the presence of spherically symmetric impurities that reduce symmetry from to , generalizing the tunneling potential method and providing analytic examples with arbitrary wall thickness.
