We show that the rate of relaxation is an important characteristic of the dynamics of critical systems undergoing second order phase transition, which are, in fact, still in effective motion even after the order parameter is reaching its steady state value. As a model system, we investigate the instability of the orientational state of a nematic liquid crystal ached on by a laser field and present the measurement of the initial fluctuations that start up the decay of the unstable state.

Abstract
We show that the rate of relaxation is an important characteristic of the dynamics of critical systems undergoing second order phase transition, which are, in fact, still in effective motion even after the order parameter is reaching its steady state value. As a model system, we investigate the instability of the orientational state of a nematic liquid crystal ached on by a laser field and present the measurement of the initial fluctuations that start up the decay of the unstable state.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
