Unified Theory of Relaxation in Equilibrium and Nonequilibrium Glass-Forming Liquids
Zi-Long Wang, Qi-Lu Yuan, Yun-Jiang Wang +4
Understanding how structural relaxation evolves from equilibrium to nonequilibrium conditions remains a central problem in glass physics. Using simulations of model glass formers u…
Unifying Plasticity in Ordered and Disordered Matter using Topological and Geometrical Descriptors
Xin Wang, Yang Xu, Jin Shang +5
Identifying the regions responsible for plastic flow in amorphous solids remains an open problem, since structural disorder seems to prevent the direct application of concepts such…
Spectral Decomposition of Liquid Viscosity into Instantaneous Normal Modes
Long-Zhou Huang, Bingyu Cui, Min-Qiang Jiang +2
Viscosity, the resistance of a liquid to flow, is driven by atomic-scale friction but its microscopic origin remains poorly understood. We use a theoretical framework based on nona…
A flat-band perspective on the boson peak in amorphous solids
Shivam Mahajan, Long-Zhou Huang, Cunyuan Jiang +4
The boson peak is a characteristic anomaly of amorphous solids broadly defined as a low-energy excess in the density of states and heat capacity compared to the textbook prediction…
Topological Defects in Amorphous Solids
Matteo Baggioli, Michael L. Falk, Walter Kob
Topological defects (TDs) are crucial for understanding important physical properties of crystalline materials including mechanical failure, ion transport, and two-dimensional melt…
Tracking shear mode dynamics across the glass transition in a 2D colloidal system
Jimin Bai, Peter Keim, Matteo Baggioli
Long-wavelength collective shear dynamics are profoundly different in solids and liquids. According to the theoretical framework developed by Maxwell and Frenkel, collective shear…
