Abstract
Measurements of the correlation function below the electrohydrodynamic instability in a thin layer of a nematic liquid crystal reveal fluctuating convection patches. Their amplitude A¯, correlation length ξ, and correlation time τ can be desribed by a stochastic mean-field model. The amplitude agrees with the expected fluctuations due to thermal noise.
