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 employs a hydrodynamic framework to demonstrate that while linearized temperature correlations in a homogeneous active nematic remain unaffected by activity, spontaneous flow transitions in confined systems generate distinctive inhomogeneous temperature profiles that serve as a thermal signature of activity.
This paper introduces a novel method for generating infinite sequences of quasi-isospectral higher-order Hamiltonians by reversing the conventional Lax pair interpretation to treat the higher-order -operator as the starting point, utilizing intertwining techniques to derive new integrable systems from known solutions like those of the KdV equation.
This paper investigates photon spheres in four-dimensional static and spherically symmetric black holes within dRGT massive gravity, revealing that while standard Einstein-like black holes possess a single unstable photon sphere, specific parameter regions allow for configurations with two or no photon spheres that exhibit distinct topological charges and stability properties compared to horizonless compact objects.
This paper derives a novel exact formula for abelian observables in topologically A-twisted supersymmetric theories on using localization techniques, demonstrating the equivalence between distributional integrals and complex contour integrals via hyperfunctions while confirming agreement with the Jeffrey-Kirwan residue prescription.
This paper investigates the moat regime in dense QCD matter using a renormalized two-flavor quark-meson model, demonstrating that the regime's extent critically depends on quark-meson interactions and that a specific renormalization scheme is essential for obtaining reliable, consistent results.
This paper generalizes the covariant phase space formalism to semi-classical gravity by defining a semi-classical symplectic two-form as the sum of the gravitational symplectic form and the Berry curvature of the quantum matter state, demonstrating its slice independence and its duality to the Berry curvature in the boundary CFT within the AdS/CFT framework.
This paper demonstrates that the near-extremal vanishing horizon (EVH) geometries of AdS black holes reduce to lower-dimensional solutions conformally related to Einstein-Maxwell-Maxwell-dilaton gravity, thereby suggesting a pathway for applying higher-dimensional AdS/CFT techniques to the microscopic entropy counting of non-AdS black holes.
This paper proposes a holographic correspondence where the observed cosmic acceleration, traditionally attributed to a cosmological constant, is instead explained as an entropic effect arising from the thermodynamic properties of the boundary's quantum degrees of freedom, a model known as GREA that predicts distinct deviations from the standard CDM model in the growth of large-scale structures testable by upcoming surveys.
This paper presents a model-independent framework that uses cosmic chronometer measurements of the Hubble parameter to directly reconstruct the background effective field theory functions of dark energy, enabling the testing of various cosmological models and the constraint of specific theories like quintessence without assuming a predefined scenario.
This paper establishes a precise holographic correspondence for ball-shaped entanglement entropy in excited states by explicitly calculating CFT corrections via modular-flowed Witten diagrams and demonstrating their exact match with the quantum extremal surface formula, including backreaction-induced shape deformations of the entanglement wedge.
