Learning to control active matter [PDF]
Physical Review Research, 2021 The study of active matter has revealed novel non-equilibrium collective behaviors, illustrating their potential as a new materials platform. However, most works treat active matter as unregulated systems with uniform microscopic energy input, which we refer to as activity.

Optimal escapes in active matter. [PDF]
Eur Phys J E Soft MatterAbstract The out-of-equilibrium character of active particles, responsible for accumulation at boundaries in confining domains, determines not-trivial effects when considering escape processes. Non-monotonous behavior of exit times with respect to tumbling rate (inverse of mean persistent time) appears, as a consequence

Acoustic trapping of active matter [PDF]
Nature Communications, 2016 AbstractConfinement of living microorganisms and self-propelled particles by an external trap provides a means of analysing the motion and behaviour of active systems. Developing a tweezer with a trapping radius large compared with the swimmers’ size and run length has been an experimental challenge, as standard optical traps are too weak.

Nature’s engines: active matter [PDF]
Europhysics News, 2017 Active materials, bacteria, molecular motors, and self-propelled colloids, continuously transform chemical energy from the environment to mechanical work. Dense active matter, from layers of cells to flocks of birds, self-assembles into intricate patterns.

Frontiers in Physics, 2020 Upconverting nanoparticles typically absorb low frequency radiation and emit at higher frequencies relying upon multiphoton processes. One such type of particle is NaYF4:Yb,Er, which absorbs at 975 nm while emitting in visible radiation.

Active nematic multipoles: Flow responses and the dynamics of defects and colloids
Frontiers in Physics, 2023 We introduce a general description of localised distortions in active nematics using the framework of active nematic multipoles. We give the Stokesian flows for arbitrary multipoles in terms of differentiation of a fundamental flow response and describe ...

The Mechanics and Statistics of Active Matter [PDF]
, 2010 Active particles contain internal degrees of freedom with the ability to take in and dissipate energy and, in the process, execute systematic movement. Examples include all living organisms and their motile constituents such as molecular motors.

Computational models for active matter [PDF]
Nature Reviews Physics, 2020 A variety of computational models have been developed to describe active matter at different length and time scales. The diversity of the methods and the challenges in modeling active matter---ranging from molecular motors and cytoskeletal filaments over artificial and biological swimmers on microscopic to groups of animals on macroscopic scales ...

Entropy production and fluctuation theorems for active matter [PDF]
, 2017 Active biological systems reside far from equilibrium, dissipating heat even in their steady state, thus requiring an extension of conventional equilibrium thermodynamics and statistical mechanics.
