Quantum GraviElectro Dynamics

Annalen der Physik, EarlyView.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

On Conformally Coupled General Relativity

EPJ Web of Conferences, 2018
A gravity model based on the conformal symmetry is presented. To specify the structure of the general coordinate transformations the Ogievetsky theorem is applied. The nonlinear symmetry realization approach is used.

Quantum de Sitter horizon entropy from quasicanonical bulk, edge, sphere and topological string partition functions

Journal of High Energy Physics, 2022
Motivated by the prospect of constraining microscopic models, we calculate the exact one-loop corrected de Sitter entropy (the logarithm of the sphere partition function) for every effective field theory of quantum gravity, with particles in arbitrary ...

The reduced phase space of spherically symmetric Einstein-Maxwell theory including a cosmological constant [PDF]

, 1995
We extend here the canonical treatment of spherically symmetric (quantum) gravity to the most simple matter coupling, namely spherically symmetric Maxwell theory with or without a cosmological constant.

The Once and Future Hydrology Is Whole Earth Hydrology

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract We here argue for a new paradigm to advance pursuit of truth in global freshwater science. Our proposed Whole Earth Hydrology is hydrology that is explicitly empirical and discovery‐based, grounded in primary data, detailed at scale, and incorporates humans as essential.

A Path-integral for the Master Constraint of Loop Quantum Gravity

, 2010
In the present paper, we start from the canonical theory of loop quantum gravity and the master constraint programme. The physical inner product is expressed by using the group averaging technique for a single self-adjoint master constraint operator.

The simplicity of physical laws

Noûs, Volume 59, Issue 4, Page 957-987, December 2025.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

The radiation equation of state and loop quantum gravity corrections

, 2007
The equation of state for radiation is derived in a canonical formulation of the electromagnetic field. This allows one to include correction terms expected from canonical quantum gravity and to infer implications to the universe evolution in radiation ...

Stability and Release Characteristics of Core‐Shell Beads with Emulsion Core Under Gastrointestinal Conditions

Advanced NanoBiomed Research, Volume 5, Issue 11, November 2025.
A combined emulsion–core‐shell structure system is developed for targeted delivery of lipophilic compounds to the proximal intestine. Using vitamin D3‐loaded sunflower oil emulsions, the core‐shell structure enhances droplet stability, encapsulation efficiency, and gastric protection.
