Johari-Goldstein relaxation in quenched and irradiated chalcogenide glasses

Understanding relaxation processes in glasses is essential for linking their microscopic dynamics to macroscopic mechanical behavior. As a liquid is...

Calorimetric signature of Johari–Goldstein relaxation in fast-quenched As2Se3

The Johari–Goldstein or beta relaxation has a clear spectroscopic signature in fragile glass-formers, including many organic and metallic systems, while...

Uniqueness of glasses prepared via x-ray induced yielding

The yield point marks the beginning of plastic deformation for a solid subjected to sufficient stress, but it can alternatively...
