Active Matter, Microreversibility, and Thermodynamics
TLDR
A general nonequilibrium thermodynamics framework for the description of active matter systems is presented and predicts the existence of a reciprocal effect of diffusiophoresis back onto the reaction rate for the entire collection of colloids in the system, as well as theexistence of a clustering instability that leads to nonequ equilibrium inhomogeneous system states.
Quantifying the non-equilibrium activity of an active colloid.
TLDR
This work focuses on characterizing the transition from thermal to non-thermal fluctuations and shows that energy dissipation rates on the order of ∼kBT s-1 are measurable from finite time series data.
Photo-bioconvection: towards light control of flows in active suspensions
TLDR
The current state, developments and some of the emerging advances in the fundamentals and applications of light-induced bioconvection are discussed, with a focus on recent experimental realizations and modelling efforts.
Mesoscopic non-equilibrium measures can reveal intrinsic features of the active driving.
TLDR
This work addresses the question of can one extract information on the nature of the active driving in a system from the analysis of a two-point non-equilibrium measure, theoretically in the context of a class of elastic systems, driven out of equilibrium by a spatially heterogeneous stochastic internal driving.
Modeling chemo-hydrodynamic interactions of phoretic particles: A unified framework
Phoretic particles exploit local self-generated physico-chemical gradients to achieve self-propulsion at the micron scale. The collective dynamics of a large number of such particles is currently the…
Active matter: Quantifying the departure from equilibrium.
TLDR
Intuitively, these so-called active Ornstein-Uhlenbeck particle systems are farther from equilibrium for longer self-propulsion persistence times, and the entropy production rate, calculated from the ratio of the probabilities of the position space trajectory and its time-reversed counterpart, has a nonmonotonic dependence on the persistence time.
Thermodynamics of Active Field Theories: Energetic Cost of Coupling to Reservoirs
The hallmark of active matter is the autonomous directed motion of its microscopic constituents driven by consumption of energy resources. This leads to the emergence of large scale dynamics and…
Molecular theory of Langevin dynamics for active self-diffusiophoretic colloids.
TLDR
The results provide a description of active motion on small scales where descriptions in terms of coarse grained continuum fluid equations combined with boundary conditions that account for the presence of the colloid may not be appropriate.
Statistical Mechanics of Self-Propelled Systems
TLDR
The non-equilibrium aggregation phases of Active Matter reveal intriguing new features in the presence of an effective alignment interaction induced by the interplay between self-propulsion and excluded volume effects.
Total synthesis of colloidal matter
Atoms serve as an inspiration for colloidal self-assembly, whereby building blocks can combine and confer endless functionality using a few design principles, including directionality, valence and…

Hydrodynamics of soft active matter
TLDR
This review summarizes theoretical progress in the field of active matter, placing it in the context of recent experiments, and highlights the experimental relevance of various semimicroscopic derivations of the continuum theory for describing bacterial swarms and suspensions, the cytoskeleton of living cells, and vibrated granular material.
Living Crystals of Light-Activated Colloidal Surfers
TLDR
A form of self-organization from nonequilibrium driving forces in a suspension of synthetic photoactivated colloidal particles is demonstrated, which leads to two-dimensional "living crystals," which form, break, explode, and re-form elsewhere.
Motility-Induced Phase Separation
TLDR
A selective overview of the fast-developing field of MIPS, focusing on theory and effects, is given, which generally breaks down at higher order in gradients.
Active Particles in Complex and Crowded Environments
Differently from passive Brownian particles, active particles, also known as self-propelled Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy from their…
Bacterial ratchet motors
TLDR
It is shown that asymmetric environments can produce a spontaneous and unidirectional rotation of nanofabricated objects immersed in an active bacterial bath and highlights the technological implications of active matter’s ability to overcome the restrictions imposed by the second law of thermodynamics on equilibrium passive fluids.
Polar patterns of driven filaments
TLDR
A minimal polar-pattern-forming system that consists of highly concentrated actin filaments propelled by immobilized molecular motors in a planar geometry is demonstrated, identifying weak and local alignment interactions to be essential for the observed formation of patterns and their dynamics.
The Mechanics and Statistics of Active Matter
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…
Activity-induced phase separation and self-assembly in mixtures of active and passive particles.
TLDR
It is found that phase separation from an initially disordered mixture can occur with as little as 15% of the particles being active, and it is shown that a system prepared in a suitable fully segregated initial state reproducibly self-assembles an active "corona," which triggers crystallization of the passive core by initiating a compression wave.
Emergence of macroscopic directed motion in populations of motile colloids
TLDR
It is reported that dilute populations of millions of colloidal rolling particles self-organize to achieve coherent motion in a unique direction, with very few density and velocity fluctuations, in the polar-liquid state.
Collective behavior of thermally active colloids.
TLDR
It is shown that in this case the thermally active colloidal solution could undergo an instability at a critical laser intensity, which has similarities to a supernova explosion.
