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: quantum Hall effect | Statement: [Klaus von Klitzing, hasDiscovered, quantum Hall effect]

Target entity: quantum Hall effect
Context triple: [Klaus von Klitzing, hasDiscovered, quantum Hall effect]

• A. Shubnikov–de Haas effect
  The Shubnikov–de Haas effect is a quantum oscillatory phenomenon in the electrical resistance of conductors and semiconductors subjected to strong magnetic fields at low temperatures, used to probe their electronic structure and Fermi surface.
• B. 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.
• C. Aharonov–Casher effect
  The Aharonov–Casher effect is a quantum mechanical phenomenon in which a neutral particle with a magnetic moment acquires a measurable phase shift when moving around a line of electric charge, illustrating the significance of electromagnetic potentials.
• D. Composite fermion
  A composite fermion is a quasiparticle formed by an electron bound to an even number of magnetic flux quanta, playing a key role in explaining the fractional quantum Hall effect.
• E. Aharonov–Bohm effect
  The Aharonov–Bohm effect is a quantum mechanical phenomenon in which charged particles are influenced by electromagnetic potentials in regions where the classical electromagnetic fields are zero, revealing the physical significance of potentials in quantum theory.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: quantum Hall effect
Triple: [Klaus von Klitzing, hasDiscovered, quantum Hall effect]

The quantum Hall effect is a quantum phenomenon in two-dimensional electron systems where the Hall conductance becomes quantized in integer or fractional values, revealing fundamental aspects of condensed matter physics and enabling precise resistance standards.
