Stones on a beach with beautiful blue waters and skies
Blue as far as the eye can see, from the sea across tow Keilir mountain and up to the skies
Some kayakers are on the sea with tall grasses at the foreground

Magnetoresistance in the Extreme Quantum Limit: Field-Induced Crossover to the Unitarity Limit
We theoretically investigate magnetoresistance (MR) in the extreme quantum limit (EQL), where the kinetic energy becomes significantly smaller than the cyclotron energy, using the Kubo formula with Green's functions and the $T$-matrix approximation. We uncover a magnetic-field-induced crossover in the scattering rate: $1/τ\propto B^2$ in the Born regime and $1/τ\propto B^{-2}$ in the unitarity limit. This crossover gives rise to distinct MR behaviors in the EQL, characterized by linear transv…
