Abstract:


Particles in a solvent might indirectly influence other particles by perturbing their surrounding fluid, these are standardly known as hydrodynamic interactions. Soft matter systems have components typically in the micrometer range where thermal fluctuations are relevant, and when these components are able to move (e. g. bacteria), the systems  become active and might display very varied and  interesting properties.  Albeit hydrodynamic interactions are in principle always present in solution, their contribution is  frequently not yet well-known, specially for systems out of equilibrium. In this talk, I will introduce the most relevant concepts and summarize various examples in which the effect of hydrodynamics can be evaluated, mainly by means of mesoscopic computer simulations.
