Colloquium

Title: Onsager Principle in Soft Matter Dynamics

Speaker:  Masao Doi, Beihang University

Location: Room 111, Physics Building

Time: 15:00-16:00, Wed, Nov 5, 2014
 

Abstract:
In the celebrated paper on the reciprocal relation for the kinetic coefficients in irreversible processes, Onsager extended Rayleigh's principle of the least energy dissipation to general irreversible processes.  In this presentation, I shall show that this principle is very convenient in discussing the non-linear and non-equilibrium phenomena in soft matter. As an example, I shall discuss the flow of colloidal suspensions and deformation of gels driven by chemical potential gradient of solvent.
