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.
This paper investigates the Joule-Thomson expansion and thermodynamic efficiency of a deformed AdS-Schwarzschild black hole in the presence of quintessence, demonstrating how the deformation parameters , , and collectively govern the system's heating-cooling behavior, thermal stability, and heat engine efficiency.
This paper demonstrates that the Laser Interferometer Space Antenna (LISA) can detect and constrain the masses and self-interaction strengths of axion-like particles forming gravitational atoms around black holes by analyzing the dephasing effects they induce on gravitational waveforms from extreme- and intermediate-mass-ratio inspirals.
This paper formulates junction conditions for Scalar-Tensor-Vector Gravity (STVG) to model gravitational collapse, demonstrating that an interior FLRW spacetime can match with an exterior Reissner-Nordström-like spacetime via a charged shell to form RN-like black holes in finite proper time.
This paper investigates the scattering, absorption, and greybody factors of spin-0 particles by electrically charged black holes within two Lorentz-violating gravity models (the bumblebee and Kalb-Ramond models), utilizing the partial waves method to demonstrate how Lorentz violation parameters and electric charge influence these physical processes.
This paper proposes a renormalizable and unitary model of quantum gravity that utilizes a Lagrange multiplier field to restrict one-loop quantum corrections to the Einstein-Hilbert action while ensuring the recovery of classical Einstein field equations.
This paper investigates slow-roll inflation within Kaniadakis and dual Kaniadakis cosmologies, demonstrating that while the deformation parameter is tightly constrained by Planck data, viable inflationary scenarios compatible with current observations can be achieved, suggesting a potential link between non-extensive thermodynamics and early universe physics.
This study demonstrates that seasonal seismic noise variations at the Einstein Telescope's Sardinia candidate site have only a minor impact (a few percent) on detector sensitivity and signal-to-noise ratios for compact binary coalescence events, confirming the site's suitability for achieving low-frequency gravitational wave detection goals.
This paper derives the standard gravitational lensing time delay formula from exact null geodesics in the Schwarzschild-de Sitter metric, identifying a higher-order correction intrinsic to the Schwarzschild geometry that does not introduce new cosmological dependencies beyond those already present in angular diameter distances and the redshift prefactor.
This paper investigates how various dark matter halo profiles (King, Hernquist, and Moore) affect the shadows of rotating Kerr-like black holes and concludes that while the presence of dark matter increases the shadow radius compared to a vacuum Kerr black hole, the specific halo profile has a negligible impact on the shadow's size and shape, rendering it an ineffective tool for distinguishing between different dark matter distributions in galactic centers.
This paper presents updated experimental constraints on the gravitational inverse-square law at short ranges, offering a consistent formalism to compare diverse tabletop and high-energy collider results with theoretical extensions of general relativity, including extra-dimensional models.
