The generalized susceptibility of dislocation segment in nondissipative crystal

[摘要] Oscillations of a dislocation segment dependence on the external forces are considered. Expressions are obtained for matrix elements which are expressed by means of the generalized susceptibilities matrix of dislocation oscillators. Elimination of non-physical features in the range of large wave numbers was made within the Peierls dislocation model. An expression was obtained describing the low-frequency asymptotic behavior of the diagonal and non-diagonal elements of the generalized susceptibilities matrix of dislocation oscillators.
