Expanded claim page · assertion 1 of 3

three hybrid modes are one short

Obstruction / no-goAuditor

A stated candidate class or identification has been ruled out under explicit assumptions. checks assumptions, certificates, counterexamples and stopping rules.

Exact assertion

The reported YIG photon–magnon–phonon device is a genuine triple-strong-coupling system, but its rotating-frame matrix is an irreducible three-node chain. With both couplings nonzero that Jacobi matrix has simple eigenvalues and only one dark direction. Three hybrid species are therefore not the same object as one bright direction plus a protected two-dimensional dark space.

What this commits us to

A specified candidate class fails under explicit assumptions. The conclusion does not automatically extend to mechanisms outside that class.

Logical anatomy

Scope

Chapter “The admissibility frontier”, section “three hybrid modes are one short”. This is assertion 1 of 3 in that section.

Evidence posture

Check the assumptions defining the ruled-out candidate class; the no-go does not automatically extend beyond that class.

Research move

checks assumptions, certificates, counterexamples and stopping rules.

Verification route

  1. Recover the declared objects and assumptions from the controlling documents.
  2. Check the calculation, construction, obstruction or stopping rule on those same objects.
  3. Compare the source conclusion with the exact assertion above; do not strengthen its verbs or enlarge its domain.
  4. Apply the status rule and retain every named external dependency.

What would move or defeat this claim

Break one of the no-go assumptions in a controlled construction, or show that the alleged obstruction does not follow within its stated class.
