详细

The mutual influence of the primary and secondary order parameters when torsion is applied under high pressure is studied. Equilibrium and nonequilibrium cases are considered. The first is realized with a continuous increase in torque, and the second when studying the transition from one state to another, described by a traveling wave. The consideration was carried out on the basis of Landau's thermodynamic theory.
