Abstract
Phenomenological model of chiral polar smectics is introduced with interactions up to the fourth neighboring layers. The minimization of the free energy gives three stable structures: the ferroelectric Sm C* phase, the antiferroelectric Sm C*A phase and the hellicoidally modulated structure of the Sm C*H phase. The phase Sm C*α can be recognized as the Sm C*H phase below Sm A phase and as the Sm C*FI2 phase or as the Sm C*FI1 phase when appearing between the Sm C* phase and the Sm C*A phase. Stability of these phases is analyzed and the phase diagram in the space of model parameters is presented.
