[Soft-matter] Soft Matter and Stat Phys Seminar on 11 Mar 2022 [online]

[Maciej Lisicki]

Dear Soft Matter Colleagues and Friends,

On Friday 11 March 2022 at 9:30AM we are hosting a seminar during which

John Shaw (University of Arkansas, IFT UW)

will give a talk

Two necessary conditions for the stability of simple loops

Abstract
Many self-formed flow networks in nature are loopy, and these loops can occur because of adaptation to fluctuating boundary conditions. However, this control has not been thoroughly tested at the scale of a single loop. We explore two conditions that control loop formation in a three-node equilateral network. First, we find that the location of the absolute maximum discharge to the network must change for a loop to form. Second, if there is a super-linear relationship between link conductivity and discharge, then there is a limit to how unequal link conductivities can be. This preliminary work suggests that the switching of dominant nodes, and parity of link conductivites should be hallmarks of stable loops in nature.

The seminar will be conducted on Zoom
https://us02web.zoom.us/j/82784273907 <https://us02web.zoom.us/j/82784273907>
and will begin at 9:30AM.
