A unified picture of phonon anomalies in crystals and glasses
Alessio Zaccone
Phonon spectra in solids often display anomalies that defy the simple Debye law, most prominently the van Hove singularity in crystals and the boson peak in glasses. Although tradi…
Impact of high pressure on reversible structural relaxation of metallic glass
Nguyen K. Ngan, Anh D. Phan, Alessio Zaccone
We theoretically investigate the temperature dependence of the reversible structural relaxation time and diffusion constant of metallic glasses under pressure. The compression not…
Soft mode theory of ferroelectric phase transitions in the low-temperature phase
Luigi Casella, Alessio Zaccone
Historically, the soft mode theory of ferroelectric phase transitions has been developed for the high-temperature (paraelectric) phase, where the phonon mode softens upon decreasin…
Plasmon energy losses in shear bands of metallic glass
Maximilian Grove, Martin Peterlechner, Harald Rösner +3
Shear bands resulting from plastic deformation in cold-rolled AlYFe metallic glass were observed to display alternating density changes along their propagation d…
Relaxation and vibrational properties in metal alloys and other disordered systems
Alessio Zaccone
The relaxation dynamics and the vibrational spectra of amorphous solids, such as metal alloys, have been intensely investigated as well separated topics in the past. The aim of thi…
Unified theory of vibrational spectra in amorphous materials
Matteo Baggioli, Alessio Zaccone
The phonon spectra of solids, described through the measurable vibrational density of states (VDOS), provide a wealth of information about the underlying atomic structure and bondi…
