Journal of Economic Geology, 2019 Introduction The mineralogical and textural characteristics of rock materials have an important influence on physico-mechanical properties. The effects of some textural characteristics like grain size (Brace, 1961), grain shape (Cox and Budhu, 2008 ...

Two-dimensional spectroscopy for the study of ion coulomb crystals. [PDF]
, 2014 Ion Coulomb crystals are currently establishing themselves as a highly controllable test bed for mesoscopic systems of statistical mechanics. The detailed experimental interrogation of the dynamics of these crystals, however, remains an experimental ...

Buckling Transitions and Clock Order of Two-Dimensional Coulomb Crystals
Physical Review X, 2016 Crystals of repulsively interacting ions in planar traps form hexagonal lattices, which undergo a buckling instability towards a multilayer structure as the transverse trap frequency is reduced.

Statistical mechanics of crystal nuclei of hard spheres
The Journal of Chemical PhysicsIn the study of crystal nucleation via computer simulations, hard spheres are arguably the most extensively explored model system. Nonetheless, even in this simple model system, the complex thermodynamics of crystal nuclei can sometimes give rise to counterintuitive results, such as the recent observation that the pressure inside a critical nucleus is ...

Multiscale Modelling of Self-Organization of Non-Equilibrium Point Defects in Irradiated α-Zirconium
Успехи физики металлов, 2017 This work is devoted to a comprehensive detailed study of a pure zirconium with non-equilibrium point defects induced by irradiation within the framework of the multiscale modelling scheme by using quantum-mechanics methods, molecular dynamics, and the ...

A mesoscopic approach to diffusion phenomena in mixtures [PDF]
, 2005 The mesosocpic concept is applied to the theory of mixtures. The aim is to investigate the diffusion phenomenon from a mesoscopic point of view. The domain of the field quantities is extended by the set of mesoscopic variables, here the velocities of the

Classical microscopic theory of dispersion, emission and absorption of light in dielectrics [PDF]
, 2014 This paper is a continuation of a recent one in which, apparently for the first time, the existence of polaritons in ionic crystals was proven in a microscopic electrodynamic theory.

Wulff construction in statistical mechanics and in combinatorics
, 2000 We present the geometric solutions to some variational problems of statistical mechanics and combinatorics. Together with the Wulff construction, which predicts the shape of the crystals, we discuss the construction which exhibits the shape of a typical ...

Study of size effects in thin films by means of a crystal plasticity theory based on DiFT [PDF]
, 2007 In a recent publication, we derived the mesoscale continuum theory of plasticity for multiple-slip systems of parallel edge dislocations, motivated by the statistical-based nonlocal continuum crystal plasticity theory for single-glide due to Yefimov et ...

Statistical mechanics of defects in polymer liquid crystals
Journal de Physique II, 1992 We develop a continuum theory for the statistical mechanics of thermally activated point defects in the nematic and hexagonal phases of polymer liquid crystals. In the nematic phase, there are elementary splay defects (chain ends and hairpins), and in the hexagonal phase, there are both splay defects and twist defects.
