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…
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…
The nature of non-phononic excitations in disordered systems
Walter Schirmacher, Matteo Paoluzzi, Felix Cosmin Mocanu +4
Using heterogeneous-elasticity theory (HET) and a generalisation of HET theory (GHET), obtained by applying a newly developed procedure for obtaining the continuum limit of the gla…
Finding defects in glasses through machine learning
Simone Ciarella, Dmytro Khomenko, Ludovic Berthier +4
Structural defects control the kinetic, thermodynamic and mechanical properties of glasses. For instance, rare quantum tunneling two-level systems (TLS) govern the physics of glass…
Microscopic observation of two-level systems in a metallic glass model
Felix C. Mocanu, Ludovic Berthier, Simone Ciarella +4
The low-temperature quasi-universal behavior of amorphous solids has been attributed to the existence of spatially-localized tunneling defects found in the low-energy regions of th…
Relationship between two-level systems and quasi-localized normal modes in glasses
Dmytro Khomenko, David R. Reichman, Francesco Zamponi
Tunnelling Two-Level Systems (TLS) dominate the physics of glasses at low temperatures. Yet TLS are extremely rare and it is extremely difficult to directly observe them $\it{in \,…
