Abstract

From the heat-capacity studies of several different liquid-crystal compounds, each with an isotropic (I)-smectic-A (SmA)-smectic-C (SmC) [or chiral-smectic-C (SmC*)] transition sequence, one possible general behavior is found between t0 and TACTIA. Here TAC and TIA denote the SmA-SmC(-SmC*) and I-SmA transition temperatures. The important parameter t0 characterizes the full width at the half-height of the mean-field heat-capacity anomaly associated with the SmA-SmC or SmA-SmC* transition and features the crossover from an ordinary mean-field-like behavior to a mean-field-tricritical-like behavior as the temperature of the system moves away from the transition temperature.
