Title: Tales of tails: Elastohydrodynamics of microscale motion
Speaker: Maciej Lisicki, University of Warsaw and UPenn
Abstract: A look into the microworld reveals plethora of swimming microorganisms, which display a rich variety of shapes and swimming gaits. Despite this diversity, physics of microscale imposes universal limitations on their propulsion strategies. In my talk, I will review the basic properties of Stokes flows and their consequences on swimming. Next, I will show an artificial system of microscale oil droplets that have the ability to swim due to a surface phase transition driven by environmental temperature fluctuations. I will demonstrate how a coarse-grained elastohydrodynamic model can be successfully employed to quantitatively describe the motion of droplets. I will also show a couple of other examples where a simplified elastohydrodynamic model proves useful for the prediction of diffusive properties.

Title: Frustrated Assemblies: Describing Matter from Within
Speaker: Efi Efrati, Weizmann Institute of Science
Abstract: Frustrated assemblies are comprised of ill-fitting building blocks whose favored local relative arrangement cannot be globally realized. In fact, most self assembled structures contain some degree of frustration. In some cases, the frustration is locally resolved and leads to little or no structural consequence, while in other cases it dominates the assembly's size, shape, and response properties. In this talk, I will present different manifestations of geometric frustration as they naturally arise in molecular crystals, liquid crystals, spin systems, and nanoparticle assemblies. To theoretically study these assemblies we resort to an intrinsic approach in which matter is described only through local properties available to an observer residing within the material. The frustration is then quantified by the geometric compatibility conditions whose structure allows us to classify the frustration and predict the assembly's behavior without explicitly solving for the ground state of the system.
