← ScienceWhich outcome occurs when high pressure reduces band overlap in cerium?
A)Insulator-metal transition occurs gradually
B)A Mott transition initiates localization✓
C)Superconductivity is immediately enhanced
D)Pauli paramagnetism becomes temperature dependent
💡 Explanation
A Mott transition initiates localization because reduced band overlap minimizes electron delocalization, increasing Coulomb repulsion. Therefore electron localization occurs, rather than a smooth band change because high pressure strengthens Coulomb effects.
