Effective temperature of active matter [PDF]
Physical Review E, 2011 We follow the dynamics of an ensemble of interacting self-propelled motorized particles in contact with an equilibrated thermal bath. We find that the fluctuation-dissipation relation allows for the definition of an effective temperature that is ...

Nano/Micromotors in Active Matter. [PDF]
Micromachines (Basel), 2022 Nano/micromotors (NMMs) are tiny objects capable of converting energy into mechanical motion. Recently, a wealth of active matter including synthetic colloids, cytoskeletons, bacteria, and cells have been used to construct NMMs. The self-sustained motion

Active Matter on Asymmetric Substrates [PDF]
SPIE Proceedings, 2011 For collections of particles in a thermal bath interacting with an asymmetric substrate, it is possible for a ratchet effect to occur where the particles undergo a net dc motion in response to an ac forcing.

Effective temperature of active complex matter
, 2011 We use molecular dynamics simulations to study the dynamics of an ensemble of interacting self-propelled semi-flexible polymers in contact with a thermal bath. Our intention is to model complex systems of biological interest.

A colloidal viewpoint on the sausage catastrophe and the finite sphere packing problem
Nature Communications, 2023 It is commonly believed that the most efficient way to pack a finite number of equal-sized spheres is by arranging them tightly in a cluster. However, mathematicians have conjectured that a linear arrangement may actually result in the densest packing ...

Control cell migration by engineering integrin ligand assembly
Nature Communications, 2022 Engineering peptide assembly that controls integrin ligand presentation on the molecular level possesses by far the highest ligand density, expanding the perspective of ligand-density-dependent modulation.

Braiding Dynamics in Active Nematics
Frontiers in Physics, 2022 In active matter systems, energy consumed at the small scale by individual agents gives rise to emergent flows at large scales. For 2D active nematic microtubule (ANMT) systems, these flows are largely characterized by the dynamics of mobile defects in ...

Dynamics of topological defects in the noisy Kuramoto model in two dimensions
Frontiers in Physics, 2022 We consider the two-dimensional (2D) noisy Kuramoto model of synchronization with short-range coupling and a Gaussian distribution of intrinsic frequencies, and investigate its ordering dynamics following a quench. We consider both underdamped (inertial)
