Ashkin–Teller joint structure benchmark
Family 233: The joint critical Ashkin–Teller current limit. First application triage, 9 October 2026 Australia/Brisbane.
Problem and potential new use
Lattice researchers can compare height and both nested current-cluster collections jointly rather than testing separate marginal observables.
Applicability and commercial boundary
The critical line, boundary conditions and admissible lattice approximations do not extend to arbitrary coupled models or guarantee fast sampling.
Initial business decision
Research infrastructure. Buyer budget, commercial novelty and profitability are unvalidated.
Next verification action
Identify finite joint statistics that distinguish a correct shared-field coupling from separate marginal fits.
Evidence scope
