Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Rabi frequency | Statement: [Isidor Isaac Rabi, notableConcept, Rabi frequency]

Target entity: Rabi frequency
Context triple: [Isidor Isaac Rabi, notableConcept, Rabi frequency]

• A. Huang–Rhys factor
  The Huang–Rhys factor is a dimensionless parameter in solid-state and molecular spectroscopy that quantifies the strength of electron–phonon (vibronic) coupling during electronic transitions.
• B. Einstein coefficients
  Einstein coefficients are parameters in quantum theory that quantify the probabilities of absorption, spontaneous emission, and stimulated emission of radiation by atoms or molecules.
• C. Rydberg constant
  The Rydberg constant is a fundamental physical constant that characterizes the limiting value of the highest wavenumber (or lowest wavelength) of any photon that can be emitted from the hydrogen atom, playing a key role in atomic spectroscopy and quantum theory.
• D. Unruh effect
  The Unruh effect is a predicted phenomenon in quantum field theory where an accelerating observer perceives what inertial observers consider vacuum as a warm bath of particles with a characteristic temperature.
• E. Fokker–Planck equation
  The Fokker–Planck equation is a partial differential equation that describes the time evolution of the probability density function of a stochastic (random) process, such as Brownian motion.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Rabi frequency
Triple: [Isidor Isaac Rabi, notableConcept, 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.
