The existence of multiple amorphous states, or polyamorphism, remains one of the most debated phenomena in disordered matter, particularly regarding its microscopic origin and impa…
Linking the pressure dependence of the structure and thermal stability to α- and \b{eta}-relaxations in metallic glasses
Jie Shen, Antoine Cornet, Alberto Ronca +13
Glasses derive their functional properties from complex relaxation dynamics that remain enigmatic under extreme conditions. While the temperature dependence of these relaxation pro…
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

Modern detector technology and highly brilliant fourth-generation synchrotrons allow to improve the temporal resolution in time-resolved diffraction studies. Profiting from this, w…
Directly observing atomic-scale relaxations of a glass forming liquid using femtosecond X-ray photon correlation spectroscopy
Tomoki Fujita, Yanwen Sun, Haoyuan Li +25
Glass forming liquids exhibit structural relaxation behaviors, reflecting underlying atomic rearrangements on a wide range of timescales. These behaviors play a crucial role in det…
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-…
Disentangling structural and kinetic components of the α-relaxation in supercooled metallic liquids
Nico Neuber, Oliver Gross, Maximilian Frey +10
The particle motion associated to the α-relaxation in supercooled liquids is still challenging scientists due to its difficulty to be probed experimentally. By combining synchrotro…
Hard X-rays as pump and probe of atomic motion in oxide glasses

Nowadays powerful X-ray sources like synchrotrons and free-electron lasers are considered as ultimate tools for probing microscopic properties in materials. However, the correct in…
Unveiling the structural arrangements responsible for the atomic dynamics in metallic glasses during physical aging
V. M. Giordano, B. Ruta
Understanding and controlling physical aging, i.e. the spontaneous temporal evolution of out-of-equilibrium systems, represents one of the greatest tasks in material science. Recen…
X-Ray Photon Correlation Spectroscopy Reveals Intermittent Aging Dynamics in a Metallic Glass
Zach Evenson, Beatrice Ruta, Simon Hechler +4
We use coherent X-rays to probe the aging dynamics of a metallic glass directly on the atomic level. Contrary to the common assumption of a steady slowing down of the dynamics usua…
