On non-phononic modes and glassy dynamics
Felix C. Mocanu, Dmytro Khomenko, Matteo Paoluzzi +4
The relationship between vibrational modes and glassy dynamics has been an important and controversial topic of study for many decades. We introduce a family of glass-forming model…
Classical versus quantum Anderson localization in disordered systems
Stefano Mossa, Giancarlo Ruocco, Walter Schirmacher
We investigate Anderson localization in three-dimensional disordered systems by comparing scalar classical waves with mass and force-constant disorder to electronic tight-binding m…
Internal Stresses as Origin of the Anomalous Low-Temperature Specific Heat in Glasses
Walter Schirmacher, Giancarlo Ruocco
We apply a recently developed theory of the nonphononic vibrational density of states (DOS) in glasses to investigate the impact of local frozen-in stresses on the low-temperature…
Further testing the validity of generalized heterogeneous-elasticity theory for low-frequency excitations in structural glasses
Walter Schirmacher, Matteo Paoluzzi, Felix Cosmin Mocanu +4
We summarize the salient features of our theory of non-phononic vibrational excitations in glasses [W. Schirmacher et al., Nature Comm. 15, 3107 (2024)]. Next, we provide further e…
