"Cracking the Glass Transition: Understanding Glassy Dynamics from Generalized Mode-Coupling Theory"

ABSTRACT


The liquid-to-glass transition remains one of the deepest unsolved problems in condensed matter physics. Although a wide diversity of theoretical views has been developed to describe this phenomenon, there is still no general consensus on the physical mechanisms underlying the transition. In this talk, I will discuss a recently developed first-principles theory of glass formation, referred to as generalized mode-coupling theory (GMCT). This theoretical framework predicts the full time-dependent dynamics of glass-forming systems using only static information as input. It will be shown that GMCT can predict the microscopic dynamics of supercooled liquids with near-quantitative accuracy over an unprecedentedly large time and temperature domain. The results support the view that activated behavior in the deeply glassy regime is inherently dynamic, rather than structural, in origin.
