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 proposes and validates a hybrid algorithm that embeds Generalized-thimble HMC within Worldvolume HMC to overcome ergodicity limitations in thin-layer simulations, thereby enabling efficient, large-scale studies of the doped Hubbard model with controlled statistical errors.
This paper introduces a "variational renormalization group" framework that combines renormalization group improvement with optimized perturbation theory to significantly reduce renormalization scale dependence in the thermal effective potential of scalar theory, thereby enhancing the precision of critical temperature and pressure predictions for applications in cosmology and condensed matter physics.
This paper constructs and analyzes electrically charged, rotating traversable wormhole solutions supported by Casimir energy and thermal stress, demonstrating that specific configurations—such as those with constant ZAMO angular velocity or radially decaying rotation—can satisfy Einstein's field equations while preserving static-like properties or mitigating unrealistic long-range frame dragging.
This paper establishes a holographic framework for symmetric quantum circuits that maps their dynamical phases to emergent gauge theories, revealing that volume-law phases function as quantum error-correcting codes with topological protection and that charge-sharpening transitions correspond to confinement transitions, with the latter exhibiting distinct behaviors (single vs. intermediate phases) depending on the symmetry group size .
This paper demonstrates that in massless QED coupled to scaleless quadratic gravity, the physical running of the electric charge coincides with the conventional -running at one loop because the gravitational sector contributes only infrared-dominated soft logarithms that do not alter the gauge-independent UV beta function.
This paper constructs a smooth interpolating family of unstable holographic geometries between confining and deconfined phases, demonstrating that both the string tension and chiral condensate decrease continuously and vanish only at the black hole limit, thereby linking the mechanisms of confinement and chiral symmetry breaking in large gauge theories.
This paper demonstrates that in Hořava-Lifshitz gravity, the compactness gap between black holes and neutron stars can vanish for fermionic objects above a certain mass threshold, potentially blurring the classification of LIGO-Virgo-KAGRA detections and suggesting that fermions with a mass of approximately 40 GeV could constitute compact dark matter.
This paper investigates the impact of adopting an -vacuum instead of the standard Bunch-Davies vacuum on inflationary observables within the Starobinsky model, concluding that Planck data and sub-millimeter gravity constraints severely limit the viability of -vacua as a de Sitter-invariant alternative.
This paper introduces SCALAR, a structured Actor-Critic-Judge framework that demonstrates how multi-turn dialogue and specific critic feedback strategies, particularly in asymmetric pairings, significantly enhance AI performance on complex theoretical physics problems, while revealing that model scaling alone cannot overcome the hardest reasoning bottlenecks.
This paper establishes the foundations of Carrollian statistical mechanics by modeling a system of interacting instantonic space-filling branes to provide a microscopic derivation of Carrollian fluid equations and formulate the initial elements of Carrollian thermodynamics.
