The Anisotropic Glassy Properties of Decagonal Quasicrystals

Anghel, Dragos Victor; Churochkin, Dmitry (Hindawi, 2013)

We use an extended version of the standard tunnelingmodel to explain the anisotropic sound absorption in decagonal quasicrystals. The glassy properties are determined by an ensemble of two level systems (TLSs), arbitrarily ...

Diffusion of elastic waves in a two dimensional continuum with a random distribution of screw dislocations

Churochkin, Dmitry; Lund Plantat, Fernando (Elsevier, 2017)

We study the diffusion of anti-plane elastic waves in a two dimensional continuum by many, randomly placed, screw dislocations. Building on a previously developed theory for coherent propagation of such waves, the incoherent ...

Multiple scattering of elastic waves by pinned dislocation segments in a continuum

Churochkin, Dmitry; Barra de la Guarda, Felipe; Lund Plantat, Fernando; Maurel, Agnes; Pagneux, Vincent (Elsevier, 2016)

The coherent propagation of elastic waves in a solid lled with a random distribution of pinned dislocation segments is studied to all orders in perturbation theory. It is shown that, within the independent scattering ...
