Excess wings and asymmetric relaxation spectra in a facilitated trap model
Camille Scalliet, Benjamin Guiselin, Ludovic Berthier
In a recent computer study, we have shown that the combination of spatially heterogeneous dynamics and kinetic facilitation provides a microscopic explanation for the emergence of…
Relaxation dynamics in the energy landscape of glass-forming liquids
Yoshihiko Nishikawa, Misaki Ozawa, Atsushi Ikeda +2
We numerically study the zero-temperature relaxation dynamics of several glass-forming models to their inherent structures, following quenches from equilibrium configurations sampl…
Statistical mechanics of coupled supercooled liquids in finite dimensions
Benjamin Guiselin, Ludovic Berthier, Gilles Tarjus
We study the statistical mechanics of supercooled liquids when the system evolves at a temperature with a field linearly coupled to its overlap with a reference configurati…
Microscopic origin of excess wings in relaxation spectra of supercooled liquids
Benjamin Guiselin, Camille Scalliet, Ludovic Berthier
Glass formation is encountered in diverse materials. Experiments have revealed that dynamic relaxation spectra of supercooled liquids generically become asymmetric near the glass t…
Rare events and disorder control the brittle yielding of well-annealed amorphous solids
Misaki Ozawa, Ludovic Berthier, Giulio Biroli +1
We use atomistic computer simulations to provide a microscopic description of the brittle failure of amorphous materials, and we assess the role of rare events and quenched disorde…
