Active fluids exhibit spontaneous flows with complex spatiotemporal structure, which have
been observed in bacterial suspensions, sperm cells, cytoskeletal suspensions, self …

Active matter, which ranges from molecular motors to groups of animals, exists at different
length scales and timescales, and various computational models have been proposed to …

A wide range of experimental systems including gliding, swarming and swimming bacteria,
in vitro motility assays, and shaken granular media are commonly described as self …

Bacteria are among the oldest and most abundant species on Earth. Bacteria successfully
colonize diverse habitats and play a significant role in the oxygen, carbon, and nitrogen …

Self-sustained turbulent structures have been observed in a wide range of living fluids, yet
no quantitative theory exists to explain their properties. We report experiments on active …

Confining surfaces play crucial roles in dynamics, transport, and order in many physical
systems, but their effects on active matter, a broad class of dynamically self-organizing …

Pattern formation is a ubiquitous phenomenon observed in nonlinear and out-of-equilibrium
systems. In equilibrium, quantum ferrofluids formed from ultracold atoms were recently …

A landmark of turbulence is the emergence of universal scaling laws, such as Kolmogorov's
E (q)~ q− 5∕ 3 scaling of the kinetic energy spectrum of inertial turbulence with the …

A suspension of swimming bacteria is possibly the simplest realization of active matter, ie a
class of systems transducing stored energy into mechanical motion. Collective swimming of …

Turbulence is a fundamental and ubiquitous phenomenon in nature, occurring from
astrophysical to biophysical scales. At the same time, it is widely recognized as one of the …
