Life is characterized by a myriad of complex dynamic processes allowing organisms to grow,
reproduce, and evolve. Physical approaches for describing systems out of thermodynamic …

The mechanical behaviour of cells is largely controlled by a structure that is fundamentally
out of thermodynamic equilibrium: a network of crosslinked filaments subjected to the action …

We review the literature on swimming in complex fluids. A classification is proposed by
comparing the length-and timescales of a swimmer with those of nearby obstacles …

The study of liquid crystals at equilibrium has led to fundamental insights into the nature of
ordered materials, as well as to practical applications such as display technologies. Active …

Engineering synthetic materials that mimic the remarkable complexity of living organisms is
a fundamental challenge in science and technology. We studied the spatiotemporal patterns …

We derive a microscopic expression for the mechanical pressure P in a system of spherical
active Brownian particles at density ρ. Our exact result relates P, defined as the force per unit …

Flocking is a paradigmatic case of self-organized collective behavior in biology and a living
example of active matter. Several models and theories have been developed in recent years …

Active matter embraces systems that self-organize at different length and time scales, often
exhibiting turbulent flows apparently deprived of spatiotemporal coherence. Here, we use a …

Collective migration of eukaryotic cells plays a fundamental role in tissue growth, wound
healing and immune response. The motion, arising spontaneously or in response to …

Binary fluid mixtures are examples of complex fluids whose microstructure and flow are
strongly coupled. For pairs of simple fluids, the microstructure consists of droplets or …
