Ferroelectric liquid crystals are presented as a simple non‐integrable Hamiltonian system. The smectic A‐smectic C * phase transition undergoes a Hopf bifurcation. The Poincaré sections of the solutions in the smectic C * phase shows the existence of spatially chaotic behavior of the molecular structure depending on temperature and external magnetic field. The smectic C‐smectic C * phase transition is also studied as second‐order derivative Hamiltonian theory.
