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 a new family of gauged supergravities featuring supersymmetric AdS vacua related to wrapped M5-branes, while formalizing sufficient conditions for consistently truncating maximal supergravity to subsectors invariant under groups not necessarily contained within the original gauge group.
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.
Using the Cosmicflows-4 catalogue and a logarithmic distance-modulus formulation, this study finds that while uncorrected local Hubble constant measurements exhibit a significant dipolar anisotropy, this signal is largely driven by peculiar velocity flows and survey selection effects rather than a fundamental breakdown of isotropic expansion, implying a limited impact on the global Hubble tension.
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.
This paper demonstrates that neither non-interacting nor self-interacting charged bosons can undergo Bose-Einstein condensation in a parallel magnetic field and rotation due to the system's quasi-one-dimensional nature, which suppresses the critical temperature and prevents off-diagonal long-range order at any nonzero temperature.
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 time-dependent perturbations in a dimensional spacetime with a three-sphere geometry, demonstrating that non-abelian Thirring deformations generically lead to anisotropic big-bang and big-crunch singularities likely resolved by string theory, while radius perturbations cause the sphere to expand to infinity in finite time without ever collapsing to zero.
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 proposes a Regge-Gribov model for interacting pomerons and odderons with negative signature, finding that while the zero-dimensional version shows no phase transition, the two-dimensional renormalization group analysis reveals a phase transition at critical intercepts that leads to unphysical phases violating projectile-target symmetry.
