Our first experimental paper has just been published 🥳! We show that motorized toys are a great experimental model system to study chiral #activematter. Exact calculations reproducing experimental results with no fitting parameter @ubics.bsky.social journals.aps.org/pre/abstract...
Depinning and activated motion of chiral self-propelled particles
We study experimentally, numerically, and analytically, the dynamics of a chiral active particle (cm-sized robots), pulled at a constant translational velocity. We show that these robots can faithfull...

I laughed at loud. These people are so pathetic; our enemies are numbskulls. They will kill us all and still not know hs physics. COWEN: The stupidest question possible: Why don’t we just make more GPUs? ALTMAN: Because we need to make more electrons. conversationswithtyler.com/episodes/sam...
New prepint w/ @demianlevis.bsky.social @natxopago.bsky.social L. Isa and E.Sesé-Sansa. 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!🥳 arxiv.org/abs/2506.15188

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...
