NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Shubnikov–de Haas effect
Context triple: [de Haas–van Alphen effect, relatedTo, Shubnikov–de Haas effect]
  • A. 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.
  • B. Szilard–Chalmers effect
    The Szilard–Chalmers effect is a nuclear chemistry phenomenon in which atoms that undergo neutron capture and become radioactive are chemically separated from their original, non-activated atoms due to recoil-induced disruption of their chemical bonds.
  • C. Zeeman effect
    The Zeeman effect is the splitting of atomic or molecular spectral lines into multiple components when subjected to an external magnetic field, revealing information about energy levels and magnetic moments.
  • D. Meissner effect
    The Meissner effect is the phenomenon in which a superconductor expels magnetic fields from its interior when cooled below its critical temperature, leading to perfect diamagnetism.
  • E. Kapitza–Dirac effect
    The Kapitza–Dirac effect is a quantum phenomenon in which a beam of particles, such as electrons or atoms, is diffracted by a standing wave of light, demonstrating the wave-particle duality of matter.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
