Phrase: Kramers–Kronig relations | Statement: [Cauchy principal value, usedIn, Kramers–Kronig relations]

Target entity: Kramers–Kronig relations
Context triple: [Cauchy principal value, usedIn, Kramers–Kronig relations]

• A. Kramers–Kronig relations chosen
  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.
• B. Kramers–Heisenberg dispersion formula
  The Kramers–Heisenberg dispersion formula is a fundamental quantum mechanical expression that describes how light is scattered by atoms and molecules, forming the basis for understanding phenomena such as Raman scattering and resonant inelastic X-ray scattering.
• C. 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.
• D. Kramers turnover theory
  Kramers turnover theory is a foundational concept in chemical physics that describes how reaction rates depend on friction or solvent viscosity, predicting a maximum (turnover) as friction varies.
• E. 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.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
