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: Kramers–Kronig relations | Statement: [Hendrik Anthony Kramers, notableWork, Kramers–Kronig relations]

Target entity: Kramers–Kronig relations
Context triple: [Hendrik Anthony Kramers, notableWork, Kramers–Kronig relations]

• A. Onsager reciprocal relations
  Onsager reciprocal relations are fundamental symmetry relations in nonequilibrium thermodynamics that link pairs of coupled fluxes and forces, showing that certain transport coefficients are equal.
• B. Esaki–Tsu relation
  The Esaki–Tsu relation is a fundamental formula in semiconductor physics that describes the nonlinear current–voltage characteristics and negative differential conductivity of electrons in superlattices under high electric fields.
• C. Wiener–Khinchin theorem
  The Wiener–Khinchin theorem is a fundamental result in signal processing and probability theory that relates a wide-sense stationary random process’s autocorrelation function to its power spectral density via the Fourier transform.
• D. Bhabha–Corben equations
  The Bhabha–Corben equations are relativistic wave equations in quantum electrodynamics that describe the dynamics of spinning charged particles, developed by physicists Homi J. Bhabha and H. C. Corben.
• 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.

Entity: Kramers–Kronig relations
Triple: [Hendrik Anthony Kramers, notableWork, Kramers–Kronig relations]

The Kramers–Kronig relations are fundamental mathematical formulas in physics that connect the real and imaginary parts of a complex response function, expressing how causality constrains the frequency-dependent behavior of physical systems.
