Resumen

The understanding of the dynamics of a glass above its devitrification
temperature remains incomplete. Here, we build a spatio-temporal map
of the relaxation dynamics of a highly stable glass into its supercooled
liquid using real-time atomic force microscopy imaging. This methodology
enables direct visualization of the progression of the liquid phase and
clarifies and quantifies the presence of localized fast mobility regions
separated by giant length scales. Our data establish a clear correlation
between dynamic length and time scales in glasses. This approach may also
be applicable to unveil the microscopic structure and dynamics of other
glass-forming systems with much shorter length and time scales, including
liquid-cooled glasses.
