Active matter is a term used to describe systems composed of many biological or artificial elements, each one with the ability to convert stored energy into movement.

Examples of active matter are collective of animals – like swarms or shoals-, bacterial suspensions and artificial swimmers.

Active matter is the great paradigm of nonequilibrium systems, therefore it is an appropriate model to construct and prove a new out-of-equilibrium thermodynamics.

This Nucleus focuses its efforts in the formulation of a theoretical framework to describe the active matter, using the tools of statistical mechanics and thermodynamics and paying special attention to problems that can be addressed numerically, theoretically and experimentally.

This knowledge will have an impact in physics, and also in other fields as biophysics and nanotechnology.
