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: London equations | Statement: [Pippard nonlocal theory, refines, London equations]

Target entity: London equations
Context triple: [Pippard nonlocal theory, refines, London equations]

• A. London equations chosen
  The London equations are fundamental relations in superconductivity that describe how magnetic fields behave inside superconductors, capturing key features like the Meissner effect and zero electrical resistance.
• B. Ginzburg–Landau theory of superconductivity
  The Ginzburg–Landau theory of superconductivity is a phenomenological framework that describes superconductors using a complex order parameter and macroscopic equations to capture phase transitions, coherence length, and magnetic behavior.
• C. Lifshitz–Kosevich formula
  The Lifshitz–Kosevich formula is a key theoretical expression in solid-state physics that describes how the amplitude of quantum oscillations in metals depends on temperature, magnetic field, and electronic properties.
• D. Bardeen–Stephen model of flux flow in superconductors
  The Bardeen–Stephen model of flux flow in superconductors is a theoretical framework that describes how magnetic vortices move and dissipate energy in type-II superconductors under applied currents and fields.
• E. Maxwell's equations
  Maxwell's equations are the fundamental set of four equations in classical electromagnetism that describe how electric and magnetic fields are generated and interact with charges and currents.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
