Abstract
Dynamic processes in glasses are crucial for unraveling the fundamentals of glass transition and material properties. A recent theoretical framework proposes a unified "doublepercolation" scenario for the α and β relaxation processes. While supported by simulations, no experimental validation has so far been presented. We here conduct a comprehensive analysis of the relaxation dissipation of more…
