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 the Laplace-space representation enables an analytical solution for primordial non-Gaussianities in the strong mixing regime of multifield inflation, revealing that the resulting cosmological collider signal is significantly larger than previously estimated due to reduced Boltzmann suppression.
This paper proposes a novel, exactly solvable mechanism using a "tower of kicks" to filter spectator dark matter fluctuations, generating a suppressed large-scale isocurvature spectrum that rises as before plateauing, thereby linking the dark matter mass to the turnover scale and favoring a low inflationary energy scale to satisfy observational constraints.
This paper calculates the complex-valued dynamical tidal response coefficients for 2+1D analogue black and white holes in rotating bathtub flows, revealing that the black hole's tidal Love number exhibits logarithmic running while its white hole counterpart's response is the complex conjugate of the black hole's.
This paper proposes that modeling the Riemann zeta function as a partition function for a "prime gas" leads to a quantum-corrected, non-singular black hole metric with a bounded Hawking temperature and an extremal remnant, while interpreting the Riemann hypothesis as the condition that arithmetic corrections to black hole thermodynamics are minimized.
This paper proposes a method to compute genus zero invariants for local Calabi-Yau fourfolds over rank-1 Fano threefolds by expressing their generating function as the functional inverse of a weight-4 Eisenstein-type modular form, a result derived by connecting modular parameterizations of the Landau-Ginzburg model with extension regulator classes and higher normal functions via Doran's twist construction.
This paper investigates whether static black holes in Massive Gravity can exhibit Aschenbach-like non-monotonic orbital velocity profiles driven by stable photon spheres rather than frame dragging, and explores the potential of this phenomenon as an observable signature distinguishing these theories from General Relativity.
This paper extends a topological approach to higher-dimensional black holes, demonstrating that the topological charge of photon spheres is universally -1, thereby guaranteeing the existence of at least one unstable photon sphere regardless of spacetime dimension.
This paper demonstrates that the negative cosmological constant in Kerr-AdS spacetime significantly enhances energy extraction via magnetic reconnection by extending the viable radial range, enabling extraction from low-spin black holes, and increasing overall efficiency and power compared to asymptotically flat counterparts.
This paper introduces "Alakazam," a high-performance Julia package designed for symbolic tensor algebra in field theory and quantum mechanics, featuring advanced capabilities like superspace support, index manipulation, and differential calculus that offer significant speed improvements over existing systems.
This paper presents a general representation-theoretic algorithm that efficiently decomposes Grassmann monomials in extended superspace into independent invariant structures by computing branching multiplicities via exact Weyl-character comparison, thereby avoiding complex Littlewood-Richardson combinatorics and providing a polynomial-time Julia implementation for arbitrary group ranks.
