Both structural glasses and disordered crystals are known to exhibit anomalous thermal, vibrational, and acoustic properties at low temperatures or low energies, what is still a matter of lively debate. To shed light on this issu

Disentangling α and β relaxation in orientationally disordered crystals with theory and experiments

Autor: Bingyu, Cui, Jonathan F, Gebbia, Josep-Lluis, Tamarit, Alessio, Zaccone

Publikováno v: Physical review. E. 97(5-1)

We use a microscopically motivated generalized Langevin equation (GLE) approach to link the vibrational density of states (VDOS) to the dielectric response of orientational glasses (OGs). The dielectric function calculated based on the GLE is compare

We develop a combined Ginzburg–Landau/micromagnetic model dealing with conventional and magnetic shape-memory properties in ferromagnetic shape-memory materials. The free energy of the system is written as the sum of structural, magnetic and magnet
