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 computes the one-loop contribution to the semiclassical partition function of static, charged near-extremal black holes in five-dimensional Einstein-Gauss-Bonnet gravity, revealing that tensor, vector, and gauge fluctuations induce universal logarithmic corrections to the entropy with a low-temperature scaling of .
This paper develops a quantum field-theoretic framework that derives a generalized Lindblad master equation to describe neutrino decoherence from momentum-changing scattering in a medium, explicitly linking decoherence parameters to scattering cross sections to probe new physics scenarios including non-standard interactions and dark matter.
This paper derives exact quasinormal modes for massive scalar, fermionic, and vector perturbations around a rotating BTZ-like black hole in Einstein-bumblebee gravity, revealing that the Lorentz symmetry breaking parameter slows field decay by affecting only the imaginary parts of the frequencies while preserving the standard BTZ real parts and confirming the validity of the AdS/CFT correspondence through universal conformal weights.
This paper investigates the scattering of two-dimensional fermion wavepackets by the Maldacena-Ludwig boundary condition, deriving explicit expressions for the resulting exotic fractionally-charged states and demonstrating that while their charge density is localized with a finite fractional integral, the expected number of fermions and anti-fermions diverges as the wavepacket becomes point-like.
This paper establishes a nonperturbative framework using analytic continuation to reconstruct regular reduced dynamics from divergent time-local generators, revealing how such divergences signal the approach to noninvertibility and identifying early-time anisotropy signatures in open quantum systems like the spin-boson model.
This paper develops a relativistic quantum field theory based on -deformed Poincaré symmetry that generalizes twisted statistics to quon-like deformations, demonstrating that while purely twisted statistics is experimentally ruled out, specific quon deformations can suppress Pauli-forbidden transitions only if superselection rules are violated, thereby implying an effective breakdown of particle indistinguishability.
This paper demonstrates that the coaction on cosmological wavefunction coefficients for conformally coupled scalars in a two-site FRW background admits an elegant diagrammatic interpretation, decomposing twisted integrals into contributions from subtopologies and cuts that clarify their analytic structure and suggest broader applicability.
This paper demonstrates that the wavefunction of the universe for conformally coupled scalars in power-law FRW cosmologies satisfies a graphical coaction that reveals its complete analytic structure through acyclic minors of Feynman graphs, thereby reproducing known kinematic flows and simplifying the extraction of discontinuities across all particle multiplicities and loop orders.
This paper demonstrates that all planar black holes conformal to a Painlevé–Gullstrand line element can be realized as analogue metrics by constructing an explicit Lagrangian, while also introducing a concept of holographic entanglement entropy valid for arbitrary conformal and blackening factors.
This paper introduces and physically interprets "soft symmetries" in topological orders—non-trivial autoequivalences that neither permute anyons nor involve symmetry fractionalization—as topological defects constructed from specific gauged SPT states, with significant implications for classifying gapped boundaries, non-invertible symmetry breaking, and symmetry-enriched phases in both (2+1)D and higher dimensions.
