Title of the talk: Title: Tales of tails: Elastohydrodynamics of microscale swimming
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 [1].
