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...

👉New preprint on avalanches in active glasses with finite persistence time. Universal behaviour of avalanches triggered by activity vs. triggered by shear: self-propulsion modulates the size of plastic events. With @ezeferrero.bsky.social #RWiese @demianlevis.bsky.social @ubics.bsky.social

Very excited to see this work out! Mixtures of active colloids, clustering, de-mixing, collective dynamics and all that. Great experiments by @lauraal.bsky.social with Lucio Isa @ethz.ch Elena Sesé and Ignacio Pagonabarraga #activematter #softmatter --> arxiv.org/abs/2506.15188

Hi ha ordre a la natura? 🍃 Si és així, quin és aquest ordre i com es manifesta? Ho descobrirem a la #FestaCiènciaUB amb l’ajuda de joguines robòtiques 🤖 web.ub.edu/ca/web/laubd... @cuca-lab.bsky.social @ubics.bsky.social

🚨 New paper out in #JSTAT : non-reciprocal Ising spins: 🧲 "Vision-cone" interactions (no multi-species) 🔥 1st & 2nd order phase transitions 🌀 Anisotropic coarsening PhDwork of AGarces @demianlevis.bsky.social @ubics.bsky.social @ub.edu iopscience.iop.org/article/10.1... #StatMech #ComplexSystems

🚨 New paper in PRL: journals.aps.org/prl/abstract... -> motion induces a topological phase transition in 2D systems of Kuramoto oscillators with random frequencies 🌀 w YRouzaire PRahmani FPeruani IPgagonabarraga @demianlevis.bsky.social @ubics.bsky.social @ub.edu #ComplexSystems #ActiveMatter

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.

What a great week! The 1st Barcelona School on non-equilibrium stat phys has been really successful. Thanks to C Calero, F Ritort, the students and all attendees sponsors and mostly, our 5 Lecturers. #statphys #bcnschoolneqstatphys

Congratulations to Mehran Kardar and Yoshiki Kuramoto, 2025 Boltzmann medalists! 🥳

The first paper of the Lab is on the cover of Soft Matter! @softmatter-journal.bsky.social pubs.rsc.org/en/Content/A... Collective motion of particles with an energy depot JPMIranda @demianlevis.bsky.social and @chantalvaleriani.bsky.social. #activematter #statmech

Está BRUTAL esta nueva técnica de ByteDance (los de TikTok) 😱 Se trata de Omnihuman-1, una IA multimodal que soporta imagen, video y audio, y la gracia es que permite crear videos de personas en cualquier relación de aspecto, y en cualquier proporción del humano (ej: cuerpo completo, retrato, etc)
