Abstract:

Collective structural arrangements and cell migration are important physical processes underlying tissue development and regeneration. Understanding the complexity of cell-cell interactions and the emergence of collective behaviors at the tissue scale presents formidable challenges both experimentally and theoretically.

In this talk, I will discuss recent theoretical work on the dynamical patterns that emerge at the tissue scale from localized rearrangements and topological defects. Using a multi-phase field model, we demonstrate that tissue fluidity stems from cell neighbor exchanges, serving as transient sources of vortical flow. This flow emerges from the relative dispersion of cells at a rate proportional to the frequency of rearrangements. Balancing collective migration with relative cell motion appears to be essential for maintaining tissue shape and fluidity. Using a cell-based model, we study the tissue's response to the presence of a vortex. While solid-like behavior tends toward conical shapes, localized fluidization triggers the transition to a tube, which is fundamental in biological tissues.

QG group meeting. Speaker: Yasha Neiman. Title: "Lightcone and unfolding - opposites yet the same".

Supersymmetry is a remarkable invariance property of physical theories which extends the usual notion of a symmetry algebra to allow for the inclusion of fermionic generators. Field theories with supersymmetry exhibit many physically relevant phenomena such as quark confinement, dynamical symmetry breaking and non-perturbative dualities in a setting where they can be studied precisely using analytic methods. Supersymmetric QFTs have also played a key role in the development of the AdS/CFT correspondence, for which they provide the best understood examples. In this course, Dr. Nick Dorey will give an overview of these developments emphasizing those things which we can calculate exactly.
