Thermodynamics and Dynamics of Glasses

Presented by Dr. Mark Ediger
Part of the 2019 MRSEC Summer Seminar Series

The thermodynamics of glasses were reviewed and how the state of a glass is influenced by different methods of preparation was briefly described. A qualitative description of glasses within the framework of the potential energy landscape was presented, with an emphasis on the configurational entropy. Relaxation processes in glasses were also discussed, including physical aging, sub-Tg relaxations, and quantum tunneling two-level systems. Along the way, the audience was led to understand what is wrong with these statements: 1) All glasses with a given composition have the same properties. 2) Nothing can move in a glass. 3) There is nothing interesting about glasses.
