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: Migdal theorem | Statement: [Migdal approximation, relatedTo, Migdal theorem]

Target entity: Migdal theorem
Context triple: [Migdal approximation, relatedTo, Migdal theorem]

• A. Migdal approximation chosen
  The Migdal approximation is a theoretical simplification in many-body physics that neglects vertex corrections in electron-phonon interactions, justified when phonon energies are much smaller than electronic energies.
• B. Gell-Mann–Low theorem
  The Gell-Mann–Low theorem is a fundamental result in quantum field theory that rigorously connects interacting quantum fields to free fields via the adiabatic switching-on of interactions, underpinning the use of perturbation theory and the Dyson series.
• C. de Bruijn–van Aardenne–Ehrenfest theorem
  The de Bruijn–van Aardenne–Ehrenfest theorem is a fundamental result in combinatorics that characterizes the number of Eulerian circuits in directed graphs, particularly de Bruijn graphs, and underpins constructions in coding theory and discrete mathematics.
• D. Gell-Mann–Okubo mass formula
  The Gell-Mann–Okubo mass formula is a relation in particle physics that predicts the mass patterns of hadrons within SU(3) flavor symmetry multiplets, providing quantitative support for the quark model and the Eightfold Way classification.
• E. Infeld–van der Waerden formalism
  The Infeld–van der Waerden formalism is a mathematical framework in general relativity that reformulates the theory using spinor calculus to describe gravitational and electromagnetic fields.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
