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.

Below are the latest papers in quantum gravity, offering fresh insights into the nature of our cosmos.
By modeling the local Universe as a superposition of inhomogeneous -Szekeres patches calibrated to Cosmicflows-4 data, this study demonstrates that accounting for local cosmic structure increases the Hubble tension by shifting the best-fit value of by approximately .
This paper proposes a holographic framework for fermionic 3D gravity in AdS, demonstrating that summing over spin structures and incorporating topological field theories yields spectral statistics consistent with fermionic 2D CFT anomalies and a newly defined random matrix theory (RMT) that accommodates fermionic spectra.
This paper employs a point particle Effective Field Theory (EFT) approach, matched with Black Hole Perturbation Theory results calculated via the Mano-Suzuki-Takasugi method, to systematically derive Next-to-Next-to Leading Order dynamical tidal Love numbers and their Renormalization Group equations for non-viscous neutron stars, including those admixed with bosonic or fermionic dark matter.
This paper computes the vacuum expectation value of the stress-energy tensor for a scalar field on a product spacetime consisting of an FLRW background and a time-dependent compact dimension by modifying the adiabatic regularization prescription to derive analytic expressions that recover known Casimir and FLRW results in specific limits.
This paper presents an optimized and significantly faster version of a higher-order WKB Mathematica code for computing quasinormal modes and greybody factors, which achieves substantial speed gains by expanding the effective potential in a Taylor series around its maximum rather than evaluating the full analytic WKB formula for each specific potential.
This paper establishes a fully relativistic framework for slowly rotating two-fluid neutron stars that reveals intrinsic collective rotational eigenmodes and demonstrates that the preservation or breakdown of rotational-tidal universality depends on dark-sector microphysics rather than simply the presence of an additional gravitationally coupled component.
This paper investigates the thermodynamic geometry and phase transitions of Anti-de Sitter black holes in ModMax, nonlinear electrodynamics, and Euler-Heisenberg theories under standard, Rényi, and Kaniadakis entropy frameworks, demonstrating that singularities in the geometrothermodynamic curvature consistently identify critical points that are preserved in their holographic dual conformal field theories.
This paper investigates the thermodynamic properties, stability, and null-geodesic structure of a Kerr-Newman black hole surrounded by quintessence and a cloud of strings, specifically analyzing how these features are modified by the inclusion of a modified dispersion relation (MDR).
This paper investigates the quantum gravity effects on particle tunneling and the thermodynamic properties of a Kerr-Newman black hole surrounded by quintessence by applying the Generalized Uncertainty Principle and gravity's rainbow framework to derive corrected Hawking temperatures, heat capacity, entropy, and equation of state parameters.
This paper re-evaluates the viability of Minimal Warm Inflation driven by an axion-like inflaton coupled to non-Abelian gauge bosons, concluding that while the clockwork mechanism fails to generate the necessary hierarchy between decay constants, effective descriptions satisfying partial-wave unitarity bounds remain consistent with observational constraints.
