Abstract:

Using the Phase Field approach a combined system of equations for stress distribution in a solid body subjected to external periodic load and order parameter for mesoscopic defect accumulation has been reduced to the problem of the first passage time to reach the last stable steady state which has been defined as a failure point. Asymptotic formula of the time-to-failure for the large in units of kT Peierls potential barrier for defect dynamics has been obtained in terms of the amplitude of the periodic load and parameters of generic Peierls potential. Asymptotic formula for remaining life of

Abstract:

The magnetization dynamics of metal-organic crystals has been studied in low frequency AC magnetic field. Four modes of domain wall motion (Debye relaxation, creep, slide and over - barrier motion (switching)) were distinguished in [MnII(H(R/S)-pn)(H2O)] [MnIII(CN)6]⋅2H2O crystals. Debye relaxation and creep of the domain walls are sensitive to Peierls relief configuration controlled by crystal lattice chirality. Structural defects and periodical Peierls potential compete in the damping of the domain walls. Driving factor of this competition is ratio of the domain wall width to the crystal lat

Abstract:

Carbon nanotube (CNT) bundles exhibit unusual mechanical properties, but nonlinear dynamics and possible energy localization in such systems have not yet been analyzed. The dynamics of a rotobreather in the form of a CNT rotating around its axis and placed in an array of similar CNTs is analyzed using a molecular dynamics model with a reduced number of degrees of freedom. The height of the Peierls–Nabarro potential associated with the discreteness of CNTs is estimated. It is found that if a CNT is given rotational kinetic energy not sufficient to overcome the Peierls–Nabarro potential, it does

Abstract:

A one-dimensional model of an elasto-plastic theory of dislocation fields is developed to model planar dislocation core structures. This theory is based on the evolution of polar dislocation densities. The motion of dislocations is accounted for by a dislocation density transport equation where dislocation velocities derive from Peach-Koehler type driving forces. Initial narrow dislocation cores are shown to spread out by transport under their own internal stress field and no relaxed configuration is found. A restoring stress of the lattice is necessary to stop this infinite relaxation and it

Abstract:

We study the charge ordering behavior under magnetic field H in the extended Hubbard model within the coherent potential approximation. At quarter filling, for small H we find that the relative variation of critical temperature is quadratic with the coefficient α smaller than the one for conventional spin-Peierls systems. For intermediate fields, a melting of the charge ordering on decreasing temperature under fixed H at various band filling is found.

Abstract:

We consider models of classical statistical mechanics satisfying natural stability conditions: a finite spin space, translation-periodic finite potential of finite range, a finite number of ground states meeting Peierls or Gertzik–Pirogov–Sinai condition. The Pirogov–Sinai theory describes the phase diagrams of these models at low temperature regimes. By using the method of doubling and mixing of partition functions we give an alternative elementary proof of the uniqueness of limiting Gibbs states at low temperatures in ground state uniqueness region.

Such materials include metals with body-centered cubic structure, semiconductors, ceramics, and many others.
