Large-scale exponential correlations of nonaffine elastic response of strongly disordered materials

D. A. Conyuh, D. V. Babin, I. O. Raikov +1

The correlation properties of the nonaffine elastic response in strongly disordered materials are investigated using the theory of correlated random matrices and supported by numer…

Effective elastic moduli of composites with a strongly disordered host material

D. A. Conyuh, A. A. Semenov, Y. M. Beltukov

The local elastic properties of strongly disordered host material are investigated using the theory of correlated random matrices. A significant increase in stiffness is shown in t…

Local elastic properties of polystyrene nanocomposites increase significantly due to non-affine deformations

Yaroslav M. Beltukov, Dmitry A. Conyuh, Ilia A. Solov'yov

We investigate the local elastic properties of polystyrene doped with SiO2 nanoparticles by analyzing the local density fluctuations. The density fluctuations were established from…

Ioffe-Regel criterion and viscoelastic properties of amorphous solids

D. A. Conyuh, Y. M. Beltukov

We show that viscoelastic effects play a crucial role in the damping of vibrational modes in harmonic amorphous solids. The relaxation of a given plane wave is described by a memor…

A random matrix approach to the boson peak and Ioffe-Regel criterion in amorphous solids

D. A. Conyuh, Y. M. Beltukov

We present a random matrix approach to study general vibrational properties of stable amorphous solids with translational invariance using the correlated Wishart ensemble. Within t…

Application of the random matrix theory to the boson peak in glasses

D. A. Conyuh, Y. M. Beltukov, D. A. Parshin

The density of vibrational states of an amorphous system is studied by using the random-matrix theory. Taking into account the most important correlations between elements o…
