Condensed Matter Seminar (News&Views series): Thursday 29 April 2021 at 5:00 pm

[CMSP Seminars Secretariat]

Virtual - Zoom Meeting

CMSP News & Views Seminar
/
/
/The News & Views Seminars are meant to address our section as a whole, 
and therefore include an extensive pedagogical introduction to the 
topic, and present the main physical ideas of the research in a way 
understandable by everybody in the section. The goal is to bridge 
distances among different subgroups of our diverse CMSP section. //The 
diversity in our section makes it a unique place for crossing bridges 
among different topics, and for cross-fertilization among seemingly 
distant fields. /

_Abstract_:

Topology plays a key role in condensed matter physics, underlying much 
of our understanding of equilibrium matter in terms of defects in 
ordered media and topologically protected states. In active systems – 
collections of entities that consume energy to generate their own motion 
and forces – topological phenomena can take on new and surprising roles. 
I will describe some of these behaviors focusing on liquid-crystalline 
active matter in two dimensions, specifically active nematic liquid 
crystals, where defects become motile particles, drive spatio-temporally 
chaotic flows, and can themselves organize in emergent ordered states.
