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.

Below are the latest papers in quantum gravity, offering fresh insights into the nature of our cosmos.
This paper promotes the global symmetry of the Schwarzian derivative to a local gauge symmetry by constructing a gauge-invariant analogue of the Schwarzian derivative through a composite field method, thereby enabling the study of topological sectors and locally invariant couplings in two-dimensional gravity contexts.
This paper validates a compact-binary mass-shell model by demonstrating that its variational predictions for radiated energy align with observational data from 38 out of 45 gravitational wave events within reported uncertainties, confirming the model's ability to capture leading-order energy scaling while highlighting specific areas for future refinement.
This paper proposes a framework associating generalized entanglement wedges in arbitrary spacetimes with algebras in a fundamental holographic description, suggesting that algebraic entropy inequalities naturally explain the inclusion monotonicity and strong subadditivity of these wedges while offering a generalized Ryu-Takayanagi formula.
This paper strengthens the case for an ultraviolet fixed point in asymptotically safe dilaton quantum gravity using gauge invariant flow equations, demonstrating that the resulting scaling solution can simultaneously describe early-universe inflation and late-time dynamical dark energy.
This paper demonstrates that the evolution operator of Polchinski's Exact Renormalization Group equation possesses an symmetry for any form of the UV cutoff function, with the special conformal generators adapting to the specific cutoff, thereby establishing a universal holographic symmetry structure for both interaction and full Wilson actions.
This paper presents a self-contained derivation of the Hamiltonian formulation of General Relativity in vielbein variables across dimensions, establishing the constraint algebra, relating it to the metric formulation, and constructing the boost generator to recover full local Lorentz symmetry within an -covariant framework.
This paper introduces a constructive asymptotic regularization method for quantum field theory that isolates and subtracts ultraviolet divergences by decomposing integrand asymptotics, thereby preserving covariance and gauge symmetry while offering a novel derivation of logarithmic terms independent of standard renormalization-group flows.
This paper investigates how braneworld corrections weaken gravity around black holes sourced by bulk matter, preventing horizon formation in sub-stellar mass environments and producing distinct, constraining optical signatures in the black hole shadow and Einstein ring radii.
This paper investigates a static, spherically symmetric ModMax black hole surrounded by perfect-fluid dark matter within Lorentz-violating Kalb-Ramond gravity, revealing how the interplay of nonlinear electrodynamics, Lorentz symmetry breaking, and dark matter modifies the horizon structure, thermodynamic stability, and phase behavior of the system.
This paper proposes that the energy-momentum tensor of the neutrino flavor vacuum in curved spacetime behaves as cold dark matter, generating a Yukawa correction to the Newtonian potential that successfully explains the flat rotation curves of spiral galaxies.
