How this entity was disambiguated
This entity first appeared as the object of triple T11244730 — 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: Rabi splitting Context triple: [Rabi oscillation, relatedTo, Rabi splitting]
-
A.
Rabi oscillation
Rabi oscillation is a quantum mechanical phenomenon in which a two-level system, such as an atom or qubit, undergoes coherent periodic transitions between its states when driven by a resonant oscillatory field.
-
B.
Dicke superradiance
Dicke superradiance is a quantum optical phenomenon in which a group of closely spaced excited atoms emit light cooperatively, producing an intense, short burst of radiation much stronger than the sum of their independent emissions.
-
C.
Floquet systems
Floquet systems are periodically driven quantum or classical systems whose behavior is analyzed using Floquet theory, often exhibiting exotic non-equilibrium phases such as time crystals.
-
D.
Rabi frequency
Rabi frequency is a fundamental quantity in quantum mechanics that characterizes the rate at which a two-level quantum system coherently oscillates between states under the influence of an oscillating external field.
-
E.
Landau–Zener formula
The Landau–Zener formula is a quantum mechanical result that gives the probability of non-adiabatic transitions between energy levels during an avoided crossing when a system’s parameters are varied in time.
- 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: Rabi splitting Description of subject: Rabi splitting is the characteristic energy-level splitting that appears when a quantum system, such as an atom or exciton, is strongly coupled to an electromagnetic field, producing two distinct hybrid light–matter states.
