A Unified Mechanistic Framework for Non-Debye Anomalies in Solids and its Application to Biological Systems

The “Unified theory of phonon in solids” (2025) recently resolved a long-standing controversy in condensed matter physics regarding the relationship between the Boson Peak (BP) and the Van Hove Singularity (VHS). By modeling solids as elastic continua embedded with local “scatterers,” this theory demonstrated that these vibrational anomalies are governed by a unified phase diagram defined by two parameters: the scatterer size and the phonon mean free path.
