Symmetry and phase transitions

Abstract: The problem of symmetry changes at phase transitions is discussed in the light of recent developments in the theory of phase transitions, as well as in terms of classical Landau theory. Various group-theoretical criteria, or selection rules, are formulated and discussed from the point of view of how well they comply with the basic requirements of the theory of phase transitions, i.e. the existence of the absolute minimum of the Landau Potential (Landau-Ginzburg-Wilson Hamiltonian) and the continuity of the transition. The physical significance of these criteria is examined.
