Ämne: Kindly reminder Scientific Fika - Today 4:00pm Hybrid Room Mega – Jeremy ‘Active matter in ice: how tiny active particles lead to huge changes?’


Dear Juniors,

Just a kindly reminder about our today session 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.
