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: Efros–Shklovskii theory | Statement: [Coulomb gap, theory, Efros–Shklovskii theory]

Target entity: Efros–Shklovskii theory
Context triple: [Coulomb gap, theory, Efros–Shklovskii theory]

• A. Eliashberg theory
  Eliashberg theory is an extension of BCS superconductivity that incorporates strong-coupling and frequency-dependent effects to more accurately describe real superconducting materials.
• B. Fermi liquid theory
  Fermi liquid theory is a framework in condensed matter physics that describes how interacting fermions in a metal behave like long-lived quasiparticles with properties similar to those of a non-interacting Fermi gas.
• C. Landau–Peierls instability
  Landau–Peierls instability is a theoretical prediction in condensed matter physics that shows how long-wavelength thermal fluctuations destroy true long-range positional order in low-dimensional crystalline systems.
• D. Landau–Pomeranchuk–Migdal effect
  The Landau–Pomeranchuk–Migdal effect is a quantum electrodynamics phenomenon in which high-energy electrons and photons in dense media experience suppressed bremsstrahlung and pair production due to multiple scattering.
• E. 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.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Efros–Shklovskii theory
Target entity description: Efros–Shklovskii theory is a framework in condensed matter physics that explains variable-range hopping conductivity in disordered systems by incorporating the effects of electron–electron interactions and the resulting Coulomb gap in the density of states.
