Experimental measurement of the persistence exponent of the planar Ising model

Using a twisted nematic liquid crystal system exhibiting planar Ising model dynamics, we have measured the scaling exponent \ensuremath{\theta}, which characterizes the time evolution $p(t)\ensuremath{\sim}{t}^{\ensuremath{-}\ensuremath{\theta}},$ of the probability $p(t)$ that the local order param...
