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: Weisskopf–Wigner theory of spontaneous emission | Statement: [Viki Weisskopf, notableWork, Weisskopf–Wigner theory of spontaneous emission]

Target entity: Weisskopf–Wigner theory of spontaneous emission
Context triple: [Viki Weisskopf, notableWork, Weisskopf–Wigner theory of spontaneous emission]

• A. Atom–Photon Interactions: Basic Processes and Applications
  Atom–Photon Interactions: Basic Processes and Applications is a comprehensive advanced physics textbook that systematically develops the quantum theory of light–matter interaction and its applications in areas such as laser physics, spectroscopy, and quantum optics.
• 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. Kramers–Heisenberg dispersion formula
  The Kramers–Heisenberg dispersion formula is a fundamental quantum mechanical expression that describes how light is scattered by atoms and molecules, forming the basis for understanding phenomena such as Raman scattering and resonant inelastic X-ray scattering.
• D. Brillouin–Wigner perturbation theory
  Brillouin–Wigner perturbation theory is a formulation of quantum mechanical perturbation theory that uses an energy-dependent effective Hamiltonian to obtain improved approximations to eigenvalues and eigenstates.
• E. Rayleigh–Schrödinger perturbation theory
  Rayleigh–Schrödinger perturbation theory is a fundamental method in quantum mechanics for approximating the energies and states of a system by treating interactions as small corrections to an exactly solvable problem.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

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: Weisskopf–Wigner theory of spontaneous emission
Triple: [Viki Weisskopf, notableWork, Weisskopf–Wigner theory of spontaneous emission]

The Weisskopf–Wigner theory of spontaneous emission is a foundational quantum electrodynamics model that explains how excited atomic states decay probabilistically by emitting photons, yielding the characteristic exponential decay law and natural linewidths of spectral lines.
