Abstract
We propose a new scenario for early cosmology, where inflationary de Sitter phase dynamically occurs. The effect emerges as a result of dynamics of the topologically nontrivial sectors in the expanding Universe. Technically the effect can be described in terms of the auxiliary fields that effectively describe the dynamics of the topological sectors in a gauge theory. Inflaton in this framework is an auxiliary topological nonpropagating field with no canonical kinetic term, similar to known topologically ordered phases in condensed matter systems. We explain many deep questions in this framework using the so-called weakly coupled ``deformed QCD'' toy model. While this theory is a weakly coupled gauge theory, it preserves all the crucial elements of strongly interacting gauge theory, including confinement, nontrivial $\ensuremath{\theta}$ dependence, degeneracy of the topological sectors, etc. We discuss a specific realization of these ideas using a scaled up version of QCD, coined as $\overline{\mathrm{QCD}}$, with the scale ${M}_{PL}\ensuremath{\gg}{\mathrm{\ensuremath{\Lambda}}}_{\overline{\mathrm{QCD}}}\ensuremath{\gg}\sqrt[3]{{M}_{EW}^{2}{M}_{PL}}\ensuremath{\sim}1{0}^{8}\text{ }\text{ }\mathrm{GeV}$. If no other fields are present in the system, de Sitter phase will be the final destination of evolution of the Universe. If other interactions are present in the system, the inflationary de Sitter phase lasts for a finite period of time. The inflation starts from the thermal equilibrium state long after the $\overline{\mathrm{QCD}}$-confinement phase transition at temperature ${T}_{i}\ensuremath{\sim}{\mathrm{\ensuremath{\Lambda}}}_{\overline{\mathrm{QCD}}}\sqrt{\frac{{\mathrm{\ensuremath{\Lambda}}}_{\overline{\mathrm{QCD}}}}{{M}_{PL}}}$. The end of inflation is triggered by the coupling with gauge bosons from the standard model. The corresponding interaction is unambiguously fixed by the triangle anomaly. The number of e-folds in the $\overline{\mathrm{QCD}}$-inflation framework is determined by the gauge coupling constant at the moment of inflation, and estimated as ${N}_{\text{inf}}\ensuremath{\sim}{\ensuremath{\alpha}}_{s}^{\ensuremath{-}2}\ensuremath{\sim}1{0}^{2}$.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
