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…
Comparison of the Helmholtz, Gibbs, and Collective-modes methods to obtain nonaffine elastic constants
Bingyu Cui, Eugene Terentjev
We review and compare the Born-Huang and the Lemaitre-Maloney's theories that lead to analytical expressions for elastic constants, accounting for affine and nonaffine deformations…
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…
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…
