Séminaire PMMH - Hughes Chaté (CEA Saclay)
Modeling suspensions of swarming bacteria with wet Vicsek models
Hugues Chaté
SPEC, CEA - Saclay & Beijing CSRC, China
After a brief introduction to active matter and some remarks about the development of the field, I will first focus on aligning dry active matter, and in particular on Vicsek-style models, the emblematic models in this class.
In a second part, I will show that wet Vicsek-style models can account for striking recent experimental results obtained on bacterial active nematics.

Instabilities of nucleation and growth of a phase change defect
Department of Mechanical and Aerospace Engineering University of California San Diego La Jolla, CA 92093-0411 Abstract A defect of phase change in density and moduli modeled as a self-similarly expanding Eshelby ellipsoidal inclusion can nucleate and grow under a critical loading. The ellipsoid possesses the (...) -

Rheology of sticky grains
In many powder technology processes, coating is applied to fine particles to control their properties or functionalize them. We investigated the role of a polymer coating made of PBS on silica beads. This material has been originally designed as a model cohesive granular material, whose cohesion can be finely (...) -

Monitoring atmospheric fossil fuel emissions using radiocarbon and global atmospheric simulations with a transport and inverse modeling system
Independent monitoring and apportioning of CO2 emissions is crucial for the verification of greenhouse gas reductions targeted by international agreements designed for climate change mitigation and adaptation. Radiocarbon (14C), found as a fractional isotope of CO2, can be used as a key tracer for fossil-derived (...)
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.
