Abstract

The observation of a new critical point in liquid-crystal phase transitions is reported. Detailed tilt angle, polarization, and susceptibility measurements of a ferroelectric liquid crystal in the presence of an applied dc electric field show that a first-order transition between the polarized smectic-A phase and the ferroelectric smectic-C phase terminates at a critical point in the temperature-field plane.
