Dear Juniors,

It is a great pleasure to announce that on Friday, February 25th at 4:00pm, Jeremy will talk about "Active matter in ice: how tiny active particles lead to huge changes?"

Abstract: Multitudes of living microorganisms are found in glaciers, ice sheets and permafrost. These active bioparticles evolve in complex environments under elaborated motions due to a range of bulk and surface interactions. Under a temperature gradient, the particle is driven toward regions of higher temperatures in a process called thermal regelation. Thermal regelation and activity control the redistribution of bioparticles in the ice core, playing a major role in paleoclimatology and climate change. Re-casting this class of regelation phenomena in the stochastic framework of active Ornstein-Uhlenbeck dynamics, we find that the activity influences particle dynamics during thermal regelation by enhancing the effective diffusion coefficient.

Please put this date in your calendar and come to discuss interesting science.
