Computing and Understanding Collective Action (CUCA) Lab.

@cuca-lab.bsky.social

We try to decipher how order and function build up in complex systems. Mostly deploying the statistical physics toolkit, combining theory, numerical simulations and experiments of model systems. @ Faculty of Physics @ub.edu + @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

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...

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.

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)
