Condensed mathematics × quantum matter

Where does a topological phase become a theorem?

A six-paper research program tracks the exact obligations between local Hamiltonians, uniform gaps, stabilized phases, and an invertible condensed phase spectrum.

Claim-status ledger

What is proved, and what is not

Conditions stay in the scope column. Epistemic labels use the corpus-wide vocabulary exactly.

IDStatusClaimScope
A.1ESTABLISHEDUniform interaction norms imply uniform Lieb-Robinson estimates.Under the stated summability and convolution hypotheses on F.
A.2ESTABLISHEDC(S,A) carries pointwise positivity and the supremum C*-norm.For compact Hausdorff S and a fixed C*-algebra A.
A.3ESTABLISHEDA uniformly gapped locus supports stable spectral flow.Requires a common gap and the relevant locality/stability assumptions.
C.1OPENControlled microscopic systems map to effective invariants.Established in selected free and low-dimensional settings, not universally.
P.1PROPOSEDThe stabilized invertible sector defines a condensed spectrum.Descent, coherences, and comparison maps remain research obligations.

Uniform locality

The analytic first arrow

Uniform interaction norms, not profiniteness, give parameter-independent Lieb-Robinson bounds. Thermodynamic dynamics also require a uniform vanishing tail.

Condensed observables

Positivity, C*-norms, and descent

Section algebras preserve fiberwise positivity and the supremum C*-norm while separating analytic structure from bare condensed algebra.

Thermodynamic gaps

Witnesses, images, and stability

A quantitative gap witness is data; the qualitative uniformly gapped locus is its propositional image, conditional on analytic input.

Microscopic → effective

Three maps, not one equivalence

Functional calculus gives a controlled free-fermion map to K-theory, while scaling, classification, and inverse realization remain distinct.

Physical realizability

From abstract class to lattice witness

Kitaev, BDI, and AKLT models verify concrete low-dimensional rows without claiming every bordism or homotopy class is realizable.
