Worm blobs as entangled living polymers: from topological active matter to flexible soft robot collectives
Recently, the study of long, slender living worms has gained attention due to their unique
ability to form highly entangled physical structures, exhibiting emergent behaviors. These …

Activity-induced collapse and arrest of active polymer rings
We investigate, using numerical simulations, the conformations of isolated active ring
polymers. We find that their behavior depends crucially on their size: Short rings (N≲ 100) …

Conformation and dynamics of partially active linear polymers
We perform numerical simulations of isolated, partially active polymers, driven out-of-
equilibrium by a fraction of their monomers. We show that, if the active beads are all …

Entropy production of nonreciprocal interactions
Z Zhang, R Garcia-Millan - Physical Review Research, 2023 - APS
Nonreciprocal interactions are present in many systems out of equilibrium. The rate of
entropy production is a measure that quantifies the time irreversibility of a system, and thus …

Surfactants and rotelles in active chiral fluids
Surfactant molecules migrate to interfaces, reduce interfacial tension, and form micelles. All
of these behaviors occur at or near equilibrium. Here, we describe active analogs of …
