For Markovian many-body quantum systems in the delocalized-decay regime, the study derived maximal decay-rate scaling Rstar proportional to N times the largest collective transition rate Gamma_max, up to asymptotic factors.

Assessment

Supported

Score: 0.8581 under ledger-default@0.3.0 at snapshot 27745

2 of 4 review checks done · 1 counted · 1 by the author only

Main unresolved issue: 3 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:e6221be0-b2b0-82b3-b64f-17aef86e7623

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.A quoted passage from nature.com was not found on the page when Galedra fetched it.

Why?

Strongest counted support: The primary study states the delocalized-decay scaling for maximal decay rate. weight 1.800000 evidence

Suppressed as dependent: The passage states that delocalized-decay bounds yield maximal decay-rate scaling R-star proportional to N times Gamma-max.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Unresolved.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.50 → log-odds 0.000000 + 1.800000 (the counted weights) = 1.800000 → probability 0.8581

Under neighbouring settings of the same model: 0.7790 to 0.9121, a spread of 0.1331.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Primary theoretical result.
The passage states that delocalized-decay bounds yield maximal decay-rate scaling R-star proportional to N times Gamma-max.

Evidence against

None.

Qualifications

The R_star proportional-to-N Gamma_max result is an asymptotic, model- and regime-dependent scaling for Markovian N-qubit systems with delocalized collective decay; it is not a universal identity for arbitrary systems or finite arrays.

From Universal scaling laws for correlated decay of many-body quantum systems Read 2026-09-29 Relevance DIRECT Steps 0 Counted

Adds Markovian/Lindblad and positive-semidefinite-matrix scope, defines Δ=O(1) delocalization, and excludes arbitrary-system and finite-size overgeneralization.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
