A solid loaded beyond the yield stress loses its elastic properties and becomes plastic. From
a microscopic point of view, this limit corresponds to the condition where plastic regions …

We have probed the atomic dynamics of two sodium silicate glasses in a wide wave vector
range by means of x-ray photon correlation spectroscopy. The wide angle setup has been …

A new experimental setup combining X-ray photon correlation spectroscopy (XPCS) in the
hard X-ray regime and a high-pressure sample environment has been developed to monitor …

Synchrotron-radiation-based techniques are a powerful tool for the investigation of
materials. In particular, the availability of highly brilliant sources has opened the possibility to …

A new experimental setup combining X-Ray Photon Correlation Spectroscopy (XPCS) in the
hard x-ray regime and a high-pressure sample environment is developed to monitor the …

In this paper, we demonstrate that the weak temperature dependence of the structure factor
of supercooled liquids, a defining feature of the glass transition, is a consequence of the …
