摘要:
We show that the existence of four order parameter relaxation modes in the dielectric spectrum of smectic C* ferroelectric liquid crystals follows directly from the symmetry properties of the chiral smectic C*-smectic A phase transition. Four macroscopic dynamic variables are thus needed to describe the dynamics of this transition and not three as suggested recently in a letter published in this journal.
