Worm blobs as entangled living polymers: from topological active matter to flexible soft robot collectives

A Deblais, KR Prathyusha, R Sinaasappel, H Tuazon… - Soft Matter, 2023 - pubs.rsc.org
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 …

Perspective: a stirring role for metabolism in cells

J Losa, S Leupold, D Alonso‐Martinez… - Molecular Systems …, 2022 - embopress.org
Based on recent findings indicating that metabolism might be governed by a limit on the rate
at which cells can dissipate Gibbs energy, in this Perspective, we propose a new …

Collective dynamics in entangled worm and robot blobs

Y Ozkan-Aydin, DI Goldman… - Proceedings of the …, 2021 - National Acad Sciences
Living systems at all scales aggregate in large numbers for a variety of functions including
mating, predation, and survival. The majority of such systems consist of unconnected …

Activity-induced collapse and arrest of active polymer rings

E Locatelli, V Bianco, P Malgaretti - Physical Review Letters, 2021 - APS
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) …

Self-Organized States from Solutions of Active Ring Polymers in Bulk and under Confinement

JP Miranda, E Locatelli, C Valeriani - Journal of Chemical Theory …, 2023 - ACS Publications
In the present work, we study, by means of numerical simulations, the structural and
dynamical behavior of a suspension of active ring polymers in bulk and under lateral …

Dynamics of active polar ring polymers

CA Philipps, G Gompper, RG Winkler - Physical Review E, 2022 - APS
The conformational and dynamical properties of isolated semiflexible active polar ring
polymers are investigated analytically. A ring is modeled as a continuous Gaussian polymer …

Conformation and dynamics of partially active linear polymers

M Vatin, S Kundu, E Locatelli - Soft Matter, 2024 - pubs.rsc.org
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

C Scholz, A Ldov, T Pöschel, M Engel, H Löwen - Science Advances, 2021 - science.org
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 …

Synchronized oscillations in swarms of nematode Turbatrix aceti

A Peshkov, S McGaffigan, AC Quillen - Soft Matter, 2022 - pubs.rsc.org
There is a recent surge of interest in the behavior of active particles that can at the same time
align their direction of movement and synchronize their oscillations, known as swarmalators …
