108th iCeMS Seminar: Assoc. Prof. Shigeyuki Komura

I shall discuss the dynamics of heterogeneity observed in multi- component fluid membranes particularly focusing on hydrodynamic effects due to the membrane and solvent. Two situations are discussed separately; above and below the miscibility transition temperature. In the former case, we calculate the wavenumber dependence of the effective diffusion coefficient by changing the temperature and/or the thickness of the bulk fluid. For the case below the transition temperature, we study the domain growth exponent in a binary membrane using a particle-based simulation method. With the addition of bulk solvent, a change in the growth exponent from two- to three-dimensional nature is observed. Along with the measurement of correlated diffusion, we conclude that the phase separation takes place through the Brownian coagulation process in our simulation.
