  • Séminaire PMMH - Blaise Delmotte, LadHyX
    Vendredi 23 septembre de 11h00 à 12h00 - Salle réunion PMMH 1
    Unexpected trapping of active particles and efficient sorting of flexible fibers with obstacles
    The motion of active or elastic particles through structured environments is ubiquitous in nature and industrial applications. Their dynamics result from the complex interplay between internal elastic stresses, activity, contact forces, thermal fluctuations and hydrodynamic interactions with the obstacles. In (...)
  • Séminaire PMMH - (Benjamin Favier, CNRS, IRPHE, Marseille)
    Vendredi 30 septembre de 11h00 à 12h00 - Salle réunion PMMH 1
    Interactions between thermal convection and a melting front
    A pure and incompressible material is confined between two plates such that it is heated from below and cooled from above. When its melting temperature is comprised between these two imposed temperatures, an interface separating liquid and solid phases appears. Depending on the initial conditions, freezing or (...)
  • Séminaire PMMH - Lydie STARON (Institut d'Alembert)
    Vendredi 7 octobre de 11h00 à 12h00 - Salle réunion PMMH 1
    Cohesion-induced weakening ? Clues from the failure of a cohesive granular step
    The failure of 2D numerical cohesive granular steps collapsing under gravity is simulated for a large range of cohesion. Focusing on the cumulative displacement of the grains, we establish a sensible criterion for capturing the failure characteristics. We are able to locate the failure in time and to identify the (...)
  • Séminaire PMMH - Sergei Nechaev (LPTMS, CNRS - Université Paris-Saclay)
    Vendredi 21 octobre de 11h00 à 12h00 - Salle réunion PMMH 1
    Anomalous scaling in stretching of a fractal polymer around a disc
    While stretching of a polymer along a flat surface is hardly different from the classical Pincus problem of pulling chain ends in free space, the role of curved geometry in conformational statistics of the stretched chain is an exciting open question. We use scaling analysis and computer simulations to examine [1] (...)
  • Séminaire PMMH - Emmanuèle Helfer (CINAM, Marseille)
    Vendredi 9 décembre de 11h00 à 12h00 - Salle réunion PMMH 1
    Biomimicking red blood cell filtration by the spleen
    Blood circulation in our vascular system is a physical tour de force. To distribute oxygen throughout the body, Red blood cells (RBCs) continuously travel through the microcirculation, through thin capillaries that are smaller than their size, and are thus highly deformable. Their deformability is periodically (...)
Information for the speakers

The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
