Resumo

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.
