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 …

Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

Cell motion inside dense tissues governs many biological processes, including embryonic
development and cancer metastasis, and recent experiments suggest that these tissues …

Active colloids are microscopic particles, which self-propel through viscous fluids by
converting energy extracted from their environment into directed motion. We first explain …

Self-propelled particles include both self-phoretic synthetic colloids and various
microorganisms. By continually consuming energy, they bypass the laws of equilibrium …

Active particles that are self-propelled by converting energy into mechanical motion
represent an expanding research realm in physics and chemistry. For micrometer-sized …

Differently from passive Brownian particles, active particles, also known as self-propelled
Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy …

These lecture notes are designed to provide a brief introduction into the phenomenology of
active matter and to present some of the analytical tools used to rationalize the emergent …

Abstract Active Brownian particles (ABPs) and Run-and-Tumble particles (RTPs) both self-
propel at fixed speed v along a body-axis u that reorients either through slow angular …

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 …
