How this entity was disambiguated
This entity first appeared as the object of triple T100378 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Cooper pair Context triple: [BCS theory of superconductivity, usesConcept, Cooper pair]
-
A.
BCS theory of superconductivity
The BCS theory of superconductivity is a fundamental microscopic theory that explains superconductivity through the formation of Cooper pairs of electrons and their collective quantum behavior in a solid.
-
B.
Bose–Einstein condensate
A Bose–Einstein condensate is an exotic state of matter formed when a dilute gas of bosons is cooled to temperatures near absolute zero, causing a large fraction of the particles to occupy the same quantum state and behave as a single quantum entity.
-
C.
W boson
The W boson is a massive elementary particle that mediates the weak nuclear force and is responsible for processes like beta decay in the Standard Model of particle physics.
-
D.
Bose–Einstein statistics
Bose–Einstein statistics is a quantum statistical framework that describes the distribution and collective behavior of indistinguishable bosons, underpinning phenomena such as Bose–Einstein condensation.
-
E.
Higgs boson
The Higgs boson is an elementary particle in the Standard Model whose associated field gives mass to other fundamental particles, confirming a key mechanism of particle physics.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Cooper pair Description of subject: A Cooper pair is a bound state of two electrons (or other fermions) that move together in a correlated way, enabling superconductivity by forming a collective quantum state with zero electrical resistance.
