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…
Yielding in dense active matter
Adil Ghaznavi, Saverio Rossi, Francesco Zamponi +1
High-density granular active matter is a useful model for dense animal collectives and could be useful for designing reconfigurable materials that can flow or solidify on command.…
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…
Scaling regimes and fluctuations of observables in computer glasses approaching the unjamming transition
Julia A. Giannini, Edan Lerner, Francesco Zamponi +1
Under decompression, disordered solids undergo an unjamming transition where they become under-coordinated and lose their structural rigidity. The mechanical and vibrational proper…
Glassy behavior of light
L. Angelani, C. Conti, G. Ruocco +1
We study the nonlinear dynamics of a multi-mode random laser using the methods of statistical physics of disordered systems. A replica-symmetry breaking phase transition is predict…
