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.

Lorentz violation and Hawking--Page metastability in Bumblebee--AdS gravity

This paper investigates Lorentz-violating effects in Bumblebee-AdS gravity by constructing a generalized off-shell Gibbs free-energy landscape, revealing that while the minimum temperature remains independent of the Lorentz-violating parameter $\alpha$ , the Hawking-Page temperature increases with $\alpha$ , thereby broadening the metastable large-black-hole window and providing a precise thermodynamic framework for diagnosing these phase transitions.

Naive Quantum Gravity

This paper proposes an alternative approach to quantum gravity that abandons the probabilistic nature of standard quantum mechanics in favor of introducing final boundary conditions, thereby creating a deterministic framework compatible with general relativity.

Characteristic gluing to extremal Kerr horizons and the third law of black hole thermodynamics in vacuum

This paper proves a non-perturbative characteristic gluing theorem that constructs vacuum spacetimes transitioning from a Schwarzschild horizon to an extremal Kerr horizon, thereby providing the first rigorous counterexample to the third law of black hole thermodynamics in vacuum.

Tidal contributions to neutron star orbital precession around Sgr $A^*$

This paper investigates tidal contributions to the orbital precession of neutron stars around Sgr A* and concludes that while these effects depend on stellar compactness and tidal Love numbers, they remain orders of magnitude smaller than general relativistic precession, making their direct detection exceptionally challenging.

Complete characterization of internal-external entanglement trade-offs in two-mode Gaussian states

This paper analytically characterizes the exact trade-off between internal and external entanglement in asymmetric two-mode Gaussian states at fixed local symplectic eigenvalues by deriving sharp, achievable bounds and a saturated monogamy-type inequality that define the complete admissible region for these entanglement measures.

Initial Data Gluing for Asymptotically Hyperbolic Spacetimes

This paper presents a new proof of Corvino-Schoen-type gluing for asymptotically hyperbolic spacetimes in arbitrary dimensions that improves upon previous smallness requirements on initial data and offers a versatile technique suitable for highly anisotropic geometric settings.

Gravitationally Induced Polarization-Angle Rotation in Pulsar-Black Hole Binaries

This paper investigates how gravitational light bending, parallel transport, and frame dragging in pulsar-black hole binaries distort and rotate the observed polarization position angle profiles, demonstrating that these relativistic effects can significantly alter the characteristic S-shaped curves and serve as a probe for the system's geometry.

Decoupled asymmetric thin-shell wormholes

This paper constructs reflection-asymmetric thin-shell wormholes by joining a Schwarzschild exterior to a deformed black hole sourced by a scalar field coupled to nonlinear electrodynamics, demonstrating that the resulting gravitational-decoupling sector enables linear stability and modifies the stable domain while providing an exact solution for rotating extensions and an estimate for gravitational-wave signals.

Quasinormal modes of thick branes in $f(R,T)$ gravity

This paper investigates tensor perturbations and quasinormal modes of thick branes in $f(R,T)=R+\alpha T$ gravity, revealing that the modified gravity parameters significantly alter the effective potential's double-barrier structure and the resulting quasinormal spectrum, thereby offering a potential observational imprint of modified gravity in braneworld scenarios.

The $C^0$ -inextendibility of Kerr spacetimes

This paper establishes the $C^0$ -inextendibility of all Kerr spacetimes, including subextremal, extremal, and overextremal regimes with positive mass and nonzero rotation, by demonstrating that the singular ring creates an obstruction characterized by unbounded proper time in fixed-endpoint causal homotopy classes that persists under continuous conformal rescalings and causal cone widening.
