What Lies Beneath: Fluid/Solid Interactions from Liquid Drops to Floating Ice

 

Abstract: Natural phenomena such as the coalescence of liquid drops or the collision of solid grains are of fundamental importance for nearly all the physical sciences and applied mathematics. Although processes such as these control the evolution and dynamics of systems on much larger scales, their individual details are often poorly understood. In this talk I will review our recent experiments that probe the mechanics of fluid and solid interfaces in a variety of manifestations. These include studies of drop coalescence, clustering in inelastic gases, the levitation of a liquid drop above a hot surface and the earthquake generated by a capsizing iceberg. Although seemingly distinct, these examples will highlight the role of precision laboratory measurements in shaping our understanding of nonequilibrium physical processes.

Nonequilibrium Thermodynamics: Free Energy, Optimal Control, and Optimal Response

 

Abstract: Molecular machines are protein complexes that convert between different forms of energy, and they feature prominently in essentially any major cell biological process. A plausible hypothesis holds that evolution has sculpted these machines to efficiently transmit energy and information in their natural contexts, where energetic fluctuations are large and nonequilibrium driving forces are strong. Toward a systematic picture of efficient, stochastic, nonequilibrium energy and information transmission, I present theoretical developments in three distinct yet related areas of nonequilibrium statistical mechanics: How can we measure how far from equilibrium a driven system is? How do we find efficient methods to push a system rapidly from one state to another? And finally, what are generic properties of systems that efficiently harness the energy and information present in environmental fluctuations?
