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: Berezinskii–Kosterlitz–Thouless theory | Statement: [XY model, importantFor, Berezinskii–Kosterlitz–Thouless theory]

Target entity: Berezinskii–Kosterlitz–Thouless theory
Context triple: [XY model, importantFor, Berezinskii–Kosterlitz–Thouless theory]

• A. Kosterlitz–Thouless–Halperin–Nelson–Young theory chosen
  The Kosterlitz–Thouless–Halperin–Nelson–Young theory is a framework in condensed matter physics that explains phase transitions in two-dimensional systems via topological defects and the unbinding of vortex–antivortex pairs, rather than conventional symmetry breaking.
• B. Yang–Lee theory
  Yang–Lee theory is a framework in statistical mechanics and phase transition theory that studies the distribution of zeros of the partition function in the complex plane to understand critical phenomena.
• C. 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.
• D. Coleman theorem on symmetry breaking in two dimensions
  The Coleman theorem on symmetry breaking in two dimensions is a result in quantum field theory stating that continuous symmetries cannot undergo spontaneous symmetry breaking in two-dimensional spacetime due to large infrared fluctuations.
• E. Coulomb gap
  The Coulomb gap is a soft depletion of electronic states near the Fermi level in disordered or localized systems, arising from long-range electron–electron interactions.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
