TL;DR: In this article, a generalized magnetic relaxation phenomenological theory, which includes the exchange relaxational term, the Bloch point dissipative dynamics was investigated, and it was shown, that consideration of exchange relaxation can explain the extremely small BP mobility value, observed in the experiment, contrary to conventional relaxation theory, based on relativistic terms.
Abstract: Abstract In the framework of a generalized magnetic relaxation phenomenological theory, which includes the exchange relaxational term, the Bloch point (BP) dissipative dynamics was investigated. It was shown, that consideration of exchange relaxation can explain the extremely small BP mobility value, observed in the experiment, contrary to conventional relaxation theory, based on relativistic terms.
TL;DR: In this article, a theory of nonlocal dielectric response is used to derive dispersion equations of normal optical waves for a structure with a periodic chain of quantum wells, and necessary conditions for the validity of the approximation of a homogeneous effetive medium with a local permittivity are formulated.

TL;DR: In this paper, the authors use the fluectuation-dissipation theorem to compare the response of an insulator and a conductor to the mean square fluctuation of the dipole moment.
Abstract: It is proposed to use, as a basic property specifying the difference between an insulator and a conductor, a static phenomenon, namely the field effect absent in the former but present in the latter. The absence or presence of the field effect is closely associated with the nature of the homogeneous linear response to a static electric field : for an insulator, it is finite; for a conductor, it depends on the volume V and tends to infinity with V. The fluectuation-dissipation theorem makes it possble to relate the nature of this response to the mean square fluctuation of the dipole moment. In an insulator, ( /V) V→ ∞ is finite; in a conductor, it is infinite
TL;DR: In this article, the diffusion coefficient D and penetration coefficient P of deuterium in the alloy Pd-53 at.% Cu were determined in the dynamic regime over the temperature range 600-1070 K. It was found that P and D in an ordered sample of the alloy having B2 structure are greater than in a quenched unordered specimen of the same alloy (quenched from 1323 K, retained 1 hr in oil) having an hcp-structure
Abstract: The method of flow determination in the dynamic regime over the temperature range 600-1070 K is used to study the diffusion coefficient D and penetration coefficient P of deuterium in the alloy Pd-53 at.% Cu. It is found that P and D for deuterium in an ordered specimen of the alloy (annealed at 733 K 24 hr, slow cooling to room temperature over 72 h) having B2 structure are greater than in a quenched unordered specimen of the same alloy (quenched from 1323 K, retained 1 hr in oil) having an hcp-structure
