Characteristics of the electric field accompanying a longitudinal acoustic wave in a metal. Anomaly in the superconducting phase
Yu. A. Avramenko,E. V. Bezuglyi,N. G. Burma,I. G. Kolobov,V. D. Fil,O. A. Shevchenko,V. M. Gokhfeld +6 more
TL;DR: The temperature dependence of the amplitude and phase of the electric potential arising at a plane boundary of a conductor when a longitudinal acoustic wave is incident normally on it is investigated theoretically and experimentally as discussed by the authors.

Magnus force and acoustic Stewart-Tolman effect in type II superconductors
V. D. Fil,D. V. Fil,A. N. Zholobenko,N. G. Burma,Yu. A. Avramenko,J. D. Kim,S. M. Choi,Sung-Ik Lee +7 more
TL;DR: In this article, it was shown that the sign of the gyroscopic force in the mixed state is the same as in the normal state, and its value (counted for one vortex of unit length) has only a weak dependence on the magnetic field.

Electric potential of the electron sound wave: Sharp disappearance in the superconducting state
TL;DR: In this article, the ac electric potential induced by the electron sound wave (a perturbation of the electron distribution function propagating with the Fermi velocity) in single crystals of high-purity gallium was studied.

Electron sound in metals
TL;DR: In this article, the amplitude-phase relations characterizing the behavior of electron sound in Ga single crystals are determined experimentally and a model of excitation of electron sounds in a compensated metal with equivalent bands is solved for a finite sample with diffuse scattering of electrons at the interfaces.

Refined Stress Analysis of Orthotropic Toroidal Shells
TL;DR: In this paper, a non-classical problem of the stress state of orthotropic toroidal shells is solved using an approach based on the straight-element model and numerical data on the distribution of deflections and stresses depending on the curvature of the shell axis are presented.
