| contents | We report real-time detection of longitudinal and transverse transport responses across distinct frequency bands in a ferromagnetic filling factor $ν$ = 1 integer quantum Hall state. By tuning $ν$, we simultaneously access the evolution of the screening environment and bulk excitation structure. The resulting asymmetric breakdown, for $ν>1$ and $ν<1$, reveals that interaction effects, rather than a single-particle band picture, dominate the transport instability. Our findings highlight the indispensability of electron-electron interactions even in integer quantum Hall phases, suggesting that distinct many-body entanglement structures underlie both integer and fractional topological phases. |
