Triadic Phase Transitions in AI Networks: Composite-Operator Scaling in Cognitive Architectures

Eduardo Salazar · 2026

Multi-agent AI architectures whose dominant collective observable is a $k$-body spin correlator $O_k\equiv\langle\phi^k\rangle$ over a $\mathbb{Z}_2$-symmetric order parameter exhibit composite-operat…

Unitary Quadratic Quantum Gravity in 4D

K. Sravan Kumar, Joao Marto · 2026

In quadratic gravity, with a positive Weyl squared coefficient, the extra spin-2 sector is shown to correspond to a dual inverted harmonic oscillator, instead of a ghost. Using the Wightman spectrum c…

Statistical Limit Theorems for Axiom A Diffeomorphisms: Exponential Mixing, Central Limit Theorem, and Large Deviations

Abdoulaye Thiam · 2026

We establish statistical limit theorems for equilibrium states of Axiom A diffeomorphisms, derived from the spectral gap of the Ruelle transfer operator established in Part I (Thiam2026a) and transfer…

Kontorovich-Lebedev-Fourier Space for de Sitter Correlators

Nathan Belrhali, Arthur Poisson, Sebastien Renaux-Petel, Denis Werth · 2026

In this work, we build a novel frequency-momentum space for $(d+1)$-dimensional de Sitter (dS) correlators from first principles. This construction follows directly from the decomposition into unitary…
