We make molecular-dynamical study of the mechanism of thermally induced orientational disordering in a polymer crystal.

The experimental data on high-temperature dielectric relaxation in linear PE samples with different thermal prehistories (slow cooling, quenching, and annealing) are described. The measurements are conducted at temperatures ranging from 0 to 80°C. Dielectric losses are measured with a high...

We revisit the problem of the molecular mechanism of the chain diffusion between crystalline and amorphous fractions in semicrystalline polyethylene (PE). There exists a long-standing controversy on the nature of the topological point defects which diffuse along the chain stems in crystallites...

We investigate a two-dimensional s2Dd strongly anisotropic crystal s2D SACd on substrate: 2D system of coupled linear chains of particles with strong intrachain and weak interchain interactions, each chain being subjected to the sine background potential. Nonlinear dynamics of one of these chains...

We investigate a 2D strongly anisotropic crystal: 2D system of coupled linear chains of particles with strong intrachain and weak interchain interactions: a generalization of the Frenkel–Kontorova (FK) model giving better approximation to polymer crystals consisting of all moving chains. We...

The necessary conditions of the applicability of the Frenkel-Kontorova one-dimensional model [the approximation of immobile neighboring chains plus sine-Gordon (continual) equation for nonlinear dynamics of the chain under consideration] to describing the dynamics of vacancies in a polymeric...

A molecular-dynamics simulation of the behavior of a twist point defect with stretching in a chain of an equilibrium polymer crystal (“united” atoms approximation for polyethylene) is performed for immobile and mobile neighboring chains. It is shown that such a defect in a cold polymer...

A molecular-dynamics model of the behavior of a vacancy in the chain of an equilibrium polymer crystal in the 'united atoms' approximation for polyethylene is developed for the first time. It is shown that a defect of this type in a polymer crystal has a soliton mobility, as opposed to...

The quantum limit for the resolution of a small force using an optical transducer of a displacement with a coherent nonmodulated pump is proved to be less than the standard quantum limit if one measures the quadrature amplitude in the output wave, squeezed by the ponderomotive nonlinearity...

Электрон, пролетающий вдоль диэлектрического волновода без оболочки, со скоростью, близкой к фазовой скорости волны, может быть использован для управления...
