We study active binary mixtures to unveil how two populations of active colloids with different motilities interact with each other.
Thanks for the great work!🥳

Published in #PhysRevLett! How nonreciprocity affects the behaviour of topological defects? they are reshaped, their annihilation can be enhanced or hindered, +1 -1 charges move differently. PhD work of YRouzaire @ub.edu @ubics.bsky.social with @demianlevis.bsky.social IPagonabarraga and DPearce.
Nonreciprocal Interactions Reshape Topological Defect Annihilation
We show how nonreciprocal ferromagnetic interactions between neighboring planar spins in two dimensions, affect the behavior of topological defects. Nonreciprocity is introduced by weighting the coupl...

What happens when two comics artists ‘meet on the page’ to explore the tragedies of the Israel-Gaza war? Art Spiegelman, best known for his Pulitzer prize-winning Holocaust memoir Maus, and Joe Sacco, author of bestselling graphic reportage Palestine, grapple with the ongoing crisis
