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 introduces Kerr generating functions within a heavy particle effective theory framework to linearize propagators and exponentiate numerators, enabling the derivation of compact all-loop scattering results for probes on Kerr black holes and providing a full four-loop calculation of leading non-linear tidal effects for neutron stars.
This paper generalizes the Hyperbolic Fracton Model to generic tessellations, revealing that while the resulting subsystem symmetries and fracton mobility exhibit a far richer and geometry-dependent complexity compared to flat lattices, the model's core holographic features, including subregion duality and area-law entropy scaling, remain robustly valid.
This paper extends the cosmological bootstrap program to scale-breaking scenarios by deriving integro-differential boundary equations with memory kernels for heavy fields with time-dependent masses, enabling analytical and numerical solutions that reveal exponentially enhanced primordial features in the squeezed bispectrum.
This paper presents an analytical study of the interior structure of 3D hairy rotating black holes, revealing a complex dynamics characterized by an infinite sequence of analytically describable Kasner epochs that ultimately evolve into a curvature singularity.
This paper investigates how the presence of primordial black holes significantly accelerates the decay of cosmic axion string loops through enhanced energy radiation, offering a potential observational signature for axion dark matter and cosmic strings.
Using an exact Andreev soft-wall holographic model, this study reveals that relativistic rotation exceeding 16% of the speed of light induces crossover phase transitions in low-density rotating QCD matter up to a critical baryon chemical potential of approximately 363.55 MeV, beyond which first-order transitions dominate.
This paper resolves a historical discrepancy in the definition of electric susceptibility in hot QCD by utilizing an exact fermion propagator and improved perturbation theory to demonstrate that the disagreement stems from the choice of thermodynamic ensemble and infrared regularization, while also constructing the susceptibility within a hadron resonance gas model for the low-temperature regime.
This paper investigates the semi-classical backreaction of a scalar field in de Sitter spacetime using Thermofield dynamics, revealing that the resulting bulk equation yields a blue-tilted power spectrum () for transient late-time modes while establishing a holographic dual to the Sp(N) model in three dimensions via the computed CFT two-point function and flow equation.
This paper demonstrates that thermal spectra in Minkowski spacetime can arise through inequivalent null-shifted wedge transformations that produce pure, non-Gibbsian states in a single chiral sector without relying on the horizon-induced entanglement characteristic of the standard Unruh effect.
This paper demonstrates that, under specific filtration assumptions, four-dimensional unitarity restricts graded unitary vertex algebras arising from the SCFT/VOA correspondence to precisely those realizable via principal Drinfel'd--Sokolov reduction of boundary-admissible affine current algebras, which correspond to Argyres--Douglas theories and minimal models.
