Impact of the application of pressure on the fundamental understanding of glass transition

Several remarkable dynamic properties of glass-forming materials have recently been discovered experimentally by the application of pressure. These properties have had a great impact on the research field of glass transition because they are general and fundamental, and not easy to explain. We review some of these experimental facts and show that they originate from the intermolecular interactions and many-body relaxation dynamics of the structural a-relaxation. While these properties are either not explained or not explainable by conventional theories and models, they can be rationalized by the coupling model.
