On the Mechanism of Activated Transport in Glassy Liquids
Vassiliy Lubchenko, Pyotr Rabochiy
We explore several potential issues that have been raised over the years regarding the "entropic droplet" scenario of activated transport in liquids, due to Wolynes and coworkers,…

Microscopically based calculations of the free energy barrier and dynamic length scale in supercooled liquids: The comparative role of configurational entropy and elasticity
Pyotr Rabochiy, Peter G. Wolynes, Vassiliy Lubchenko
We compute the temperature-dependent barrier for alpha-relaxations in several liquids, without adjustable parameters, using experimentally determined elastic, structural, and calor…
