Restructuring of the atomic condensed state under conditions of an intense external field

Abstract

This paper examines the restructuring of the collective behavior of atoms in a condensed medium during intense external loads. To describe the atomic states, the ensemble of potential contours is used, the distribution law of which is given by the synergetic potential. The parameter of restructuring of the atomic system is determined by the correlation of the variation in the potential contour at macroscopic distances. The collective excitations, possessing critical behavior, reduce to the transverse acoustic branch of phonons. Using quantum field theory the equations of motion are determined for the parameter of coherent restructuring of the potential contour and the gauge field. Superconductivity and helium 4 superfluidity are studied in an analysis of the mutually dependent behavior of the atomic subsystem and the collective mode, carried out in the framework of the synergetic approach by determining the system of Lorentzian equations for the time evolution for the share of lattice sites falling into the restructured potential contour, the shear deformation of the medium as a result of atomic restructuring, and the stress field coupled to it.
