Nonequilibrium Phenomena in Soft Matter and Biophysics

Strong nonlinearity underpins almost all aspects of nonequilibrium phenomena, and hence numerical computation is often the only avenue of attack for many problems in the field. These researchers use parallel codes to address numerical integration of the governing models (two or three dimensional in space, plus time). In some cases the models are stochastic to model microscopic degrees of freedom or fast variables removed from the description, and at times these calculations are supplemented with direct simulation of microscopic or mesoscopic models. Topics of interest include pattern formation and defect motion in mesophases, including block copolymer rheology, a mesoscopic theory of viscoelasticity, and the effect of randomness and small number statistics in the stability and robustness of model gene networks.
