This research demonstrates that entanglement scaling in interacting fermion systems can transition from power-law to logarithmic growth depending on the Rényi index, challenging previous assumptions derived solely from simplified spin models. By introducing a symmetry-aware lower bound based on charge-resolved data, the team provides a practical protocol for diagnosing anomalous scaling without requiring computationally prohibitive full state tomography. This advancement offers more accurate tools for quantifying quantum correlations in complex many-body systems where rare particle-number sectors previously masked substantial entanglement effects.
