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.

Fields on accelerating and super accelerating black holes: stability, quasinormal modes, greybody factors and strong cosmic censorship

This paper investigates the stability, quasinormal modes, and greybody factors of massless scalar, Dirac, and Maxwell fields on accelerating and super accelerating black holes described by the C-metric, revealing new mode families in the super accelerating regime and identifying potential violations of the strong cosmic censorship conjecture for scalar and Maxwell fields but not for Dirac fields.

Lamb shift of rotational energy levels in quantum gravity

This paper proposes that the coupling between quantized metric perturbations and an anisotropic quantum rigid rotor can amplify gravitational effects through the sheer number of constituents, leading to a calculable gravitational Lamb shift that offers a potential near-future experimental pathway to test the quantum nature of gravity.

Noisy Pipelines I: An end-to-end pipeline to perform multivariate noise inference for LISA

This paper introduces $\texttt{lisa-noise}$ , a fast, JAX-based end-to-end pipeline that accurately infers the multivariate noise covariance matrix for LISA data by correcting for post-processing effects and non-stationary transfer function drifts, enabling efficient and reliable global-fit analyses.

A conformal reduction for the X-ADM mass

This paper establishes the X-positive mass theorem with rigidity for asymptotically flat manifolds in all dimensions $n \geq 3$ without topological restrictions by proving that the X-ADM mass decomposes into the standard ADM mass of a scalar-flat conformal representative and a non-negative term, thereby extending the Riemannian mass–charge inequality to non-spin manifolds.

Lagrangian perturbation theory for modified gravity

This paper presents a third-order Lagrangian perturbation theory formalism for modified gravity models with scale-dependent gravitational strengths, highlighting the necessity of frame-lagging terms to recover the $\Lambda$ CDM limit and applying the framework to compute 1-loop power spectra and correlation functions in $f(R)$ gravity.

Dynamical stability of Magnetic Supramassive Neutron Stars

Using fully general-relativistic magnetohydrodynamic simulations, this study reveals that extreme magnetic fields in supramassive neutron stars can reorganize into stable, differentially rotating configurations or trigger gravitational collapse into black holes depending on the star's mass, while driving significant baryon-dominated winds.

The presence and order of QCD phase transitions from gravitational-wave observations of neutron star mergers

This paper presents a formalism using gravitational-wave inspiral data to detect first-order phase transitions in neutron star cores, demonstrating that future detectors like A+ and A# will be capable of confirming their existence within a few years of observation, while noting the inability to distinguish second- or third-order transitions or high-density first-order transitions from a standard equation of state.

Finite-range hair from a nonlocal matter sector: charged Yukawa black holes

This paper presents a new exact charged black hole solution in Einstein-Maxwell gravity featuring a finite-range, exponentially screened Yukawa hair that modifies the near-horizon geometry while preserving the Reissner-Nordström asymptotics, and demonstrates that Event Horizon Telescope observations of M87* and Sgr A* constrain this model to a regime where the Yukawa effects are strongly screened.

Nonlocality effects on fermions confined within a hard-wall potential

This paper investigates nonlocality effects on spin-1/2 fermions confined by hard-wall potentials using a modified Dirac theory, deriving analytical energy spectra for cylindrical and ring geometries that reveal how finite nonlocality shifts the effective mass and alters particle-antiparticle energy separation.

Finite Spectral Recurrences for Loop Integrals in de Sitter and Anti-de Sitter Space

This paper introduces a coordinate-free propagator algebra that generates exact finite-difference and differential-difference equations for loop integrals in de Sitter and anti-de Sitter spaces, enabling the systematic solution of multi-loop diagrams such as the two-loop watermelon and one-loop functions while recovering known AdS boundary relations.
