Quantum improved wormholes in the Dekel-Zhao dark matter halo
An ASG-modified Newton constant combined with a Dekel–Zhao dark matter halo yields traversable wormhole geometries whose shadow radius can be tuned to the EHT Sgr A* bound by choosing the ASG scale ξ/M ≈ 0.8–0.9.

Probing holographic conformal field theories
In a holographic CFT on a cylinder, a qutrit Unruh-DeWitt detector harvests more mana when the dual bulk scalar uses standard (Δ+) quantization than alternate (Δ−) quantization.

Gibbons-Hawking Entropy and BMN Strings
A proposed universal finite entropy bound for quantum gravity is introduced and linked to the Gibbons-Hawking entropy of our universe, with BMN strings suggested as an unresolved test.

Quantum coherent dynamics of quasiclassical spacetimes
Quasiclassical spacetimes are modeled as nonorthogonal coherent states whose Hamiltonian generates tunneling between geometries, recovering the semiclassical black-hole evaporation curve as the most probable path.

The Topological Multiverse as the Self-Consistent Extension of Everettian QM to Quantum Gravity
Constants of nature are claimed to be quantum variables frozen by early-universe decoherence, yielding a multiverse of branches with different effective laws.

Fermi scale from quantum gravity scaling solution
The Fermi/Planck ratio is claimed to be predictable from the analyticity of the quantum-gravity scaling solution for the cosmon-Higgs coupling, with numerics showing the coupling flows to a tiny, near-critical value.

Tame Complexity of Effective Field Theories in the Quantum Gravity Landscape
Effective field theories consistent with quantum gravity are conjectured to have uniformly bounded 'tame complexity', a quantitative measure of the information needed to specify them.
