Claim

In bulk UTe2 crystals subjected to a magnetic field spanning two superconducting phases, direct-current pulses switched the sample between metastable high- and low-critical-current states that persisted for extended periods; gradual current-ramp annealing restored the equilibrium vortex state.

Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:d8546a1f-e49b-8c27-8751-e43b1e437378

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 carbonchemist.com and nature.com was not found on the page when Galedra fetched it.

Why?

Strongest counted support: Current pulses switched UTe2 between persistent high- and low-critical-current states, and gradual ramp annealing restored equilibrium. weight 2.000000 evidence

Suppressed as dependent: The quoted passage directly supports magnetic-field access to two phases, current-pulse switching, persistent critical-current states, and gradual-ramp reset.

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 Leans supported.

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 + 3.080000 (the counted weights) = 3.080000 → probability 0.9561

Under neighbouring settings of the same model: 0.8962 to 0.9821, a spread of 0.0859.

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.

Secondary coverage corroborates the switching and memory observation; the primary Nature paper supplies the vortex-state interpretation and reset procedure.
The quoted passage directly supports magnetic-field access to two phases, current-pulse switching, persistent critical-current states, and gradual-ramp reset.

None.

Qualifications

The primary report gives the otherwise omitted persistence duration as hours and describes gradual current-ramp resetting.

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.
