Elasticity typically refers to a material's ability to store energy, whereas viscosity refers to a
material's tendency to dissipate it. In this review, we discuss fluids and solids for which this is …

In recent years, there has been growing interest in the study of chiral active materials, which
consist of building blocks that show active dynamics featuring chiral symmetry breaking, eg …

In an equilibrium thermal environment, random elastic collisions between background
particles and a tracer establish the picture of Brownian motion fulfilling the celebrated …

Ferromagnetic ferrofluids are synthetic materials consisting of magnetic nanoplatelets
dispersed in an isotropic fluid. Their main characteristics are the formation of stable …

A first-principles approach for active chiral hard disks is presented, that explicitly accounts
for steric interactions on the two-body level. We derive an effective one-body equation for the …

Odd viscosity couples stress to strain rate in a dissipationless way. It has been studied in
plasmas under magnetic fields, superfluid He 3, quantum-Hall fluids, and recently in the …

Diffusion is a fundamental aspect of transport processes in biological systems, and thus, in
the development of life itself. And yet, the diffusive dynamics of active fluids with directed …

Artificial active matters on a macroscopic scale, including vibrating particles, robots, and
camphor boats, have attracted increasing attentions due to their uniform properties, rich and …

Inertial underdamped collisions preserve the memory of physical parameters that existed
before the collision, leading to phenomena usually unseen in overdamped systems. Here …
