Quantum gravity represents the frontier where the very large meets the very small, attempting to unify Einstein's theory of gravity with the strange rules of quantum mechanics. This field explores the fundamental fabric of spacetime, seeking to understand how the universe behaves at its most extreme scales, from the heart of black holes to the moment of the Big Bang. Because these concepts often involve complex mathematics, they can feel distant to non-specialists, yet they hold the key to a complete picture of physical reality.

At Gist.Science, we bridge this gap by processing every new preprint in this category directly from arXiv. Our team provides both plain-language explanations and detailed technical summaries for each paper, ensuring that groundbreaking research is accessible to everyone, from curious students to seasoned researchers. Below are the latest papers in quantum gravity, offering fresh insights into the nature of our cosmos.

Love symmetry in higher-dimensional rotating black hole spacetimes

This paper develops a method to construct a one-parameter family of globally-defined Love symmetry generators for rotating black holes in arbitrary dimensions by matching the near-horizon Klein-Gordon operator to an $SL(2,\mathbb{R})$ Casimir, a framework that successfully recovers known 4D and 5D cases and demonstrates the separability of the massive scalar wave equation in generalized Lense-Thirring spacetimes using both Myers-Perry and Painlevé-Gullstrand coordinates.

Thermal evolution of dark matter and gravitational-wave production in the early universe from a symplectic glueball model

This paper investigates a dark matter model based on a symplectic gauge group, analyzing its thermodynamic properties near the confinement phase transition and exploring the resulting gravitational-wave production and relic abundances in the early universe.

Linearized Gravity in the Starobinsky Model: Perturbative Deviations from General Relativity

This paper investigates perturbative deviations from General Relativity in the Starobinsky $f(R)$ model by deriving an effective energy density that includes a mass-dependent correction term, which is numerically shown to diminish with distance and vanish as the model parameter $m$ increases, thereby recovering the relativistic limit.

Yang-Mills-Utiyama Theory and Graviweak Correspondence

This paper proposes a geometrical Yang-Mills framework that unifies local Lorentz and internal gauge symmetries within an extended space-time, thereby enabling the transfer of topological insights from Euclidean to Lorentzian theories and establishing a novel correspondence between gravity and the weak force.

Kerr-AdS type higher dimensional black holes with non-spherical cross-sections of horizons

This paper constructs a family of singularity-free, higher-dimensional Kerr-Anti-de Sitter-like black holes in even spacetime dimensions that feature non-spherical horizons and negatively curved conformal infinity.

Logarithmic corrections to near-extremal entropy of charged de Sitter black holes

This paper calculates universal leading-order logarithmic temperature corrections to the thermodynamic entropy of four-dimensional near-extremal Reissner-Nordström de Sitter black holes by analyzing one-loop contributions and zero modes in the cold and Nariai extremal limits within a path integral framework.

Constraining the neutron star-black hole merger rate

By incorporating spin-induced orbital precession into gravitational-wave searches for the first time, this study significantly improves detection sensitivity for neutron star-black hole binaries, leading to a 16% downward revision of their estimated merger rate and the identification of four new subthreshold candidates likely of terrestrial origin.

Interacting dark energy after DESI DR2: a challenge for $Λ$ CDM paradigm?

This paper investigates interacting dark energy using recent observational data, including DESI DR2, and finds only mild evidence for interaction that remains inconclusive when weighed against the standard $\Lambda$ CDM model through various statistical criteria.

On a lower-dimensional Killing vector origin of irreducible Killing tensors

This paper establishes conditions under which lower-dimensional symmetries of a foliated spacetime's base space, specifically arising from non-commuting Killing vectors, can be lifted to generate irreducible Killing tensors of higher rank in the full spacetime, a mechanism demonstrated through examples ranging from generalized Lense-Thirring metrics to rotating black holes in Einstein-Maxwell-Dilaton-Axion theory.

Impact of magnetic field gradients on the development of the MRI: Applications to binary neutron star mergers and proto-planetary disks

This study demonstrates that strong magnetic field gradients in post-merger environments can significantly suppress or slow the magneto-rotational instability (MRI), limiting its ability to amplify poloidal magnetic fields to only specific regions and late times ( $t \gtrsim 100$ ms) after a binary neutron star merger.
