Extranatural Inflation
read the original abstract
We present a new model of inflation in which the inflaton is the extra component of a gauge field in a 5d theory compactified on a circle. The chief merit of this model is that the potential comes only from non-local effects so that its flatness is not spoiled by higher dimensional operators or quantum gravity corrections. The model predicts a red spectrum (n ~ 0.96) and a significant production of gravitational waves (r ~ 0.11). We also comment on the relevance of this idea to quintessence.

Big Axions
Big axions are axion models from collective spontaneous breaking of a delocalized network of U(1) symmetries that realize high-quality accidental global symmetries, solve the strong CP problem, and may explain dark matter.

Deconstructing the Extra-Dimensional Axion
A 4D moose gauge theory with gauged WZW term deconstructs the 5D orbifold axion, reproducing its shift symmetry, instanton effects, and quality features via collective PNGB dynamics.

Natural Phantom Crossing from Axion-WIMP Interactions
A Z_N-symmetric WIMP sector stores the initial axion value in its relic distribution and later generates a finite-density axion potential, producing an apparent late-time phantom crossing without ghosts.

Axions on de Sitter space
Quantization of axions on dS_D yields Hilbert space H = L^2(S^1) ⊗ F with zero-mode U(1) charge, producing non-dS-invariant charged sectors and Hadamard Wightman functions that become asymptotically invariant.

DeepInflation: an AI agent for research and model discovery of inflation
An LLM agent with symbolic regression finds simple inflation potentials that match target CMB observables, but the outputs are fitted to the targets rather than independently predicted.

Axion Quality in Warped Extra-Dimension
Warped extra-dimensional Wilson-line axions can achieve high quality when non-QCD potential contributions from charged bulk fields are parametrically suppressed by geometry and brane effects.

Axion Quality in Warped Extra-Dimension
Warped extra-dimensional axion models achieve high quality when nonlocal U(1)-charged field effects are sufficiently suppressed by the warp factor and orbifold structure.

Thermal effects on Dark Matter production during cosmic reheating
Thermal corrections to reheating and freeze-in DM production rates are generally small in the computable regime but can be large in constructed counter-examples.
