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: Shubnikov–de Haas effect | Statement: [Fermi surface, probedBy, Shubnikov–de Haas effect]

Target entity: Shubnikov–de Haas effect
Context triple: [Fermi surface, probedBy, Shubnikov–de Haas effect]

• A. de Haas–van Alphen effect
  The de Haas–van Alphen effect is a quantum oscillatory phenomenon in metals where the magnetization varies periodically with applied magnetic field, allowing precise mapping of the electronic structure and Fermi surface.
• B. Zeeman effect
  The Zeeman effect is the splitting of atomic or molecular spectral lines into multiple components when subjected to an external magnetic field, revealing information about energy levels and magnetic moments.
• C. Meissner effect
  The Meissner effect is the phenomenon in which a superconductor expels magnetic fields from its interior when cooled below its critical temperature, leading to perfect diamagnetism.
• D. Fermi surface
  The Fermi surface is the boundary in momentum space separating occupied from unoccupied electron states at zero temperature, crucial for determining a metal’s electronic and superconducting properties.
• E. Stark effect
  The Stark effect is the splitting and shifting of atomic or molecular spectral lines caused by an external electric field.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
