Six-dimensional primordial black holes with memory burden effects can survive as light dark matter in a two-extra-dimension model at the 10 TeV scale, producing high-multiplicity thermal events at future colliders.
Lattice QED is established as a quantum error-correcting code beyond stabilizers, with explicit recovery operations constructed via quantum reference frames for gauge and fermionic sectors.
A quantum-action-based quantization resolves inconsistencies in second-quantizing quantum time schemes by introducing spacetime classical mechanics and a no-go theorem, yielding manifestly covariant interacting QFT via a spacetime generalization of quantum states.
In a quantum Bianchi type-I cosmology, the conditional probability density for zero volume vanishes for all clock times, resolving the classical singularity via Page-Wootters relational dynamics.
Clock time is reconstructed from the accumulated Fisher distinguishability along causally ordered physical changes, rather than being a fundamental quantity measured by clocks.
Diffeomorphism invariance qualifies as a gauge symmetry solely in the global sense, restricting the applicability of observables and rendering correlation-based accounts of physical content unfounded.
