Abstract

We have measured the coarsening exponent φ and the nontrivial scaling exponent X, which characterize how the two-time correlation function C(t,t′) scales with the correlation length L(t), C(t,t′) ∝ L (t) when t ≫ t′, for a twisted nematic liquid-crystal system quenched from the isotropic phase to the nematic phase. This system is expected to be Ising-like with φ=0.5 and λ=1.25. Our values, φ=0.515 ± 0.026, measured over two decades in time, and λ = 1.246±0.079, measured over the late time period, 30 to 150 s, are in good agreement with theory.
