Recently, many unexpected fine structures in electric, magnetic, andthermoelectric responses at extremely magnetic fields in topological materialshave attracted tremendous interest. We propose a new mechanism of quantumoscillation beyond the strong-field quantum limit for Dirac fermions. Theamplitude of the oscillation is far larger than the usual Shubnikov--de Haasoscillation. The oscillation tends to be periodic in the magnetic field B,instead of 1/B. The period of the oscillation does not depend on the Fermienergy. These behaviors cannot be described by the famous Lifshitz-Kosevichformula. The oscillation arises from a mechanism that we refer to as theinversion of the lowest Landau level, resulted from the competition between thepseudospin Dirac-type Landau levels and real-spin Zeeman spitting beyond thequantum limit. This inversion gives rise to the oscillation of the Fermi energyand conductivity at extremely large magnetic fields. This mechanism will beuseful for understanding the unexpected fine structures observed in thestrong-field quantum limit in Dirac materials.
