On the biophysics of plant morphogenesis   Arezki Boudaoud, Ecole Polytechnique   What sets the size and form of organisms is still, by large, an open question. During this talk, I will aim at a broad audience and illustrate how are addressing this question by using biophysical experiments and models applied to plant morphogenesis. On…

  AI-enhanced detection of Fractal Electronic Textures in Vanadium Dioxide  By Prof. Erica W. Carlson, Purdue University Where : The seminar will take place in a hybrid format at ESPCI, Room Cellule, building C, 3rd floor. Phases of matter and phase transitions are central concepts in condensed matter physics.  From the liquid crystal displays of our…

Freezing contact line   Thomas Séon, Institut d'Alembert   Where : The seminar will take place in a hybrid format at ESPCI, Amphi Charpak   Ice accretion on airplane, wire or roadway, formation of ice fall, ice stalactite, frozen river or aufeis, are a few examples of ice structures formed by the solidification of capillary…

Microfluidic osmotic compression of charge-stabilized colloidal dispersions: Equations of state and collective diffusion coefficients. Annick Hallez, Laboratoire de Génie Chimique, Université de Toulouse. Where : ESPCI, Amphi Holweck. Using a model coupling mass transport and liquid theory calculations for a charge-stabilized colloidal dispersion, it is possible to show that diffusion significantly limits measurement times of…

From nanocrystals to earthquakes: Universal avalanche statistics across 12 decades in length?   Karin Dahmen, Department of Physics, University of Illinois at Urbana Champaign Slowly-compressed nano-crystals, bulk metallic glasses, high entropy alloys, rocks, granular materials, and the earth all deform via intermittent slips or “quakes”. We find that although these systems span 12 decades in…
