Phrase: Shubnikov–de Haas effect | Statement: [Landau levels, areFundamentalTo, Shubnikov–de Haas effect]

Target entity: Shubnikov–de Haas effect
Context triple: [Landau levels, areFundamentalTo, Shubnikov–de Haas effect]

• A. Shubnikov–de Haas effect chosen
  The Shubnikov–de Haas effect is a quantum oscillatory phenomenon in the electrical resistance of conductors and semiconductors subjected to strong magnetic fields at low temperatures, used to probe their electronic structure and Fermi surface.
• B. 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.
• C. 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.
• D. Cotton–Mouton effect
  The Cotton–Mouton effect is a magneto-optical phenomenon in which a transverse magnetic field induces birefringence in an otherwise isotropic medium, causing the polarization of transmitted light to change.
• E. Slichter–Hebel coherence peak
  The Slichter–Hebel coherence peak is a characteristic enhancement in nuclear spin-lattice relaxation just below the superconducting transition temperature, providing key experimental evidence for conventional BCS superconductivity.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
