Unified theory of vibrational spectra in amorphous materials
Matteo Baggioli, Alessio Zaccone
The phonon spectra of solids, described through the measurable vibrational density of states (VDOS), provide a wealth of information about the underlying atomic structure and bondi…
Identifying non-affine softening modes in glassy polymer networks: A pathway to chemical design
Robert M. Elder, Alessio Zaccone, Timothy W. Sirk
Using molecular simulations and theory, we develop an explicit mapping of the contribution of molecular relaxation modes in glassy thermosets to the shear modulus, where the relaxa…
Nonaffine lattice dynamics with the Ewald method reveals strongly nonaffine elasticity of α-quartz
Bingyu Cui, Alessio Zaccone, David Rodney
A lattice dynamical formalism based on nonaffine response theory is derived for non-centrosymmetric crystals, accounting for long-range interatomic interactions using the Ewald met…
Infrasonic wave propagation in ultrasoft solids at low Reynolds numbers
Jan Maarten van Doorn, Ruben Higler, Ronald Wegh +4
The propagation of elastic waves in soft materials plays a crucial role in the spatio-temporal transmission of mechanical signals, e.g. in biological mechanotransduction or in the…
Atomistic structural mechanism for the glass transition: Entropic contribution
Dong Han, Dan Wei, Jie Yang +5
A popular Adam--Gibbs scenario has suggested that the excess entropy of glass and liquid over crystal dominates the dynamical arrest at the glass transition with exclusive contribu…
Theory of the phonon spectrum in host-guest crystalline solids with avoided crossing
Matteo Baggioli, Bingyu Cui, Alessio Zaccone
We develop an analytical model to describe the phonon dispersion relations of host-guest lattices with heavy guest atoms (rattlers). Crucially, the model also accounts for phonon d…
Analytical prediction of logarithmic Rayleigh scattering in amorphous solids from tensorial heterogeneous elasticity with power-law disorder
Bingyu Cui, Alessio Zaccone
The damping or attenuation coefficient of sound waves in solids due to impurities scales with the wavevector to the fourth power, also known as Rayleigh scattering. In amorphous so…
Hydrodynamics of disordered marginally-stable matter
Matteo Baggioli, Alessio Zaccone
We study the vibrational spectra and the specific heat of disordered systems using an effective hydrodynamic framework. We consider the contribution of diffusive modes, i.e. the 'd…
Theory of elastic constants of athermal amorphous solids with internal stresses
Bingyu Cui, Giancarlo Ruocco, Alessio Zaccone
A new microscopic derivation of the elastic constants of amorphous solids is presented within the framework of nonaffine lattice dynamics, which makes use of a perturbative form of…
Radial distribution function of Lennard-Jones fluids in shear flows from intermediate asymptotics
L. Banetta, A. Zaccone
Determining the microstructure of colloidal suspensions under shear flows has been a challenge for theoretical and computational methods due to the singularly-perturbed boundary-la…
