Abstract
We derive explicit strong-field asymptotics for the normalized differential resistance in Hall field-induced resistance oscillations (HIRO) within the Vavilov-Aleiner-Glazman kinetic framework. For a single-harmonic density of states, the leading oscillation amplitude is set by the full backscattering rate . Extending the theory to a two-harmonic density of states, we show that the off-diagonal mixed kernel admits an exact single-integral representation, from which the strong-field asymptotics follow directly. The resulting odd harmonics, notably and , have coefficients determined by combinations of and , while the leading amplitude remains unchanged. On exact-kernel mock data generated and fit within the same model, with and held fixed, the resulting extraction protocol recovers , and—when the harmonics are resolved— to subpercent accuracy, with providing a consistency check on the disorder description.
