Abstract
Using a twisted nematic liquid crystal system exhibiting planar Ising model dynamics, we have measured the scaling exponent theta, which cha racterizes the time evolution p(t)similar to t(-theta), of the probabi lity p(t) that the local order parameter has not switched its state by the time t. For 0.4 sec-200 set following the phase quench, the syste m exhibits scaling behavior and, measured over this interval, theta=0. 19+/-0.03, in good agreement with theoretical analysis and numerical s imulations.
