Break-down of the relationship between α-relaxation and equilibration in hydrostatically compressed metallic glasses
Antoine Cornet, Jie Shen, Alberto Ronca +20
Glasses encode the memory of any thermo-mechanical treatment applied to them. This ability is associated to the existence of a myriad of metastable amorphous states which can be pr…
On the interplay of liquid-like and stress-driven dynamics in a metallic glass former observed by temperature scanning XPCS
Maximilian Frey, Nico Neuber, Sascha Sebastian Riegler +16
Modern detector technology and highly brilliant fourth-generation synchrotrons allow to improve the temporal resolution in time-resolved diffraction studies. Profiting from this, w…
High-pressure X-ray photon correlation spectroscopy at fourth-generation synchrotron sources
Antoine Cornet, Alberto Ronca, Jie Shen +8
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 pressure…
Pressure-induced non-monotonic crossover of steady relaxation dynamics in a metallic glass
Xin Zhang, Hongbo Lou, Beatrice Ruta +8
Relaxation dynamics, as a key to understand glass formation and glassy properties, remains an elusive and challenging issue in condensed matter physics. In this work, in situ high-…
Denser glasses relax faster: a competition between rejuvenation and aging during in-situ high pressure compression at the atomic scale
A. Cornet, G. Garbarino, F. Zontone +15
A fascinating feature of metallic glasses is their ability to explore different configurations under mechanical deformations. This effect is usually observed through macroscopic ob…

The routine atomic-resolution structure determination of single particles is expected to have profound implications for probing the structure-function relationship in systems rangi…
Relaxation dynamics, Softness and Fragility of Microgels with Interpenetrated Polymer Networks
Valentina Nigro, Barbara Ruzicka, Beatrice Ruta +4
Microgels are elastic and deformable particles with a hybrid nature between that of polymers and colloids and unconventional behaviours with respect to hard colloids. We investigat…
Hard X-rays as pump and probe of atomic motion in oxide glasses
