Motile cells often explore natural environments characterized by a high degree of structural complexity. Moreover cell motility is also intrinsically noisy due to spontaneous random reorientations and speed fluctuations. This interplay of internal and external noise sources gives rise to a complex dynamical behavior that can be strongly sensitive to details and hard to model quantitatively. In striking contrast to this general picture we show that the mean residence time of swimming bacteria… 
Boundary-interior principle for microbial navigation in geometric confinement
When the motion of a motile cell is observed closely, it appears erratic, and yet the combination of nonequilibrium forces and surfaces can produce striking examples of collective organization in
Emergent probability fluxes in confined microbial navigation
It is found that the boundary’s curvature determines the nonequilibrium probability fluxes of the motion, which opens the possibility to decipher the most probable trajectories of motile cells and may enable the design of geometries guiding their time-averaged motion.
A geometric criterion for the optimal spreading of active polymers in porous media
This work performs Brownian dynamics simulations of active stiff polymers undergoing run-reverse dynamics, and so mimic bacterial swimming, in porous media, and discovers a geometric criterion for the optimal spreading, which emerges when their run lengths are comparable to the longest straight path available in the porous medium.
Enhanced propagation of motile bacteria on surfaces due to forward scattering
It is shown that micro-obstacles influence the propagation of peritrichously flagellated bacteria on a flat surface in a non-monotonic way and this finding provides insight on the emerging dynamics of chiral active matter in complex environments and inspires possible routes to control microbial ecology in natural habitats.
Crowding-Enhanced Diffusion: An Exact Theory for Highly Entangled Self-Propelled Stiff Filaments.
It is shown that an exact expression derived for a single self-propelled filament with motility parameters as input can predict the nontrivial spatiotemporal dynamics over the entire range of length and timescales.
Random motion of a circle microswimmer in a random environment
We simulate the dynamics of a single circle microswimmer exploring a disordered array of fixed obstacles. The interplay of two different types of randomness, quenched disorder and stochastic noise,
Mean path length invariance in wave-scattering beyond the diffusive regime
Diffusive random walks feature the surprising property that the average length of all possible random trajectories that enter and exit a finite domain is determined solely by the domain boundary.
Invariance properties of random curves: an approach based on integral geometry
Traveled lengths statistic is a key quantity for characterizing stochastic processes in bounded domains. For straight lines and diffusive random walks, the average length of the trajectories through
The environment topography alters the transition from single-cell populations to multicellular structures in Myxococcus xanthus
It is experimentally demonstrated that the topography alters single-cell motility and multicellular organization in M. xanthus, and the cells’ interaction with particles drastically modifies the dynamics of cellular aggregation, leading to changes in the number, size and shape of the fruiting bodies.
Feedback-controlled active brownian colloids with space-dependent rotational dynamics
Using a magnetic control with a feedback loop, the authors program the dynamics of active Brownian particles by updating their rotational diffusion coefficient depending on their locations, adding a new dimension to the control of active matter.


An invariance property of diffusive random walks
Starting from a simple animal-biology example, a general, somewhat counter-intuitive property of diffusion random walks is presented. It is shown that for any (non-homogeneous) purely diffusing
Hydrodynamic Trapping of Swimming Bacteria by Convex Walls.
The results demonstrate that the main mechanism for wall entrapment is hydrodynamic in nature and show the possibility of inhibiting cell adhesion, and thus biofilm formation, using convex features of appropriate curvature.
Invariance property of wave scattering through disordered media
It is demonstrated that an equivalent invariance relation also holds for the scattering of waves in resonant structures as well as in ballistic, chaotic or in Anderson localized systems.
Microswimmers in patterned environments
A novel species of microswimmers whose active motion is due to the local demixing of a critical binary liquid mixture and can be easily tuned by illumination is developed, which can be employed to develop advanced sorting, classification and dialysis techniques.
A Wall of Funnels Concentrates Swimming Bacteria
The funnel effect is shown, which shows that when a population of bacteria is exposed to a microfabricated wall of funnel-shaped openings, the random motion of bacteria through the openings is rectified by tracking (trapping) of the swimming bacteria along the funnel wall.
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
Ciliary contact interactions dominate surface scattering of swimming eukaryotes
Direct experimental evidence is presented that the surface scattering of both mammalian sperm cells and unicellular green algae is primarily governed by direct ciliary contact interactions, and it is predicted and experimentally verified the existence of optimal microfluidic ratchets that maximize rectification of initially uniform Chlamydomonas reinhardtii suspensions.
Ratchet Effects in Active Matter Systems
This work describes ratchet reversals produced by collective effects and the use of active ratchets to transport passive particles, and discusses future directions including deformable substrates or particles, the role of different swimming modes, varied particle-particle interactions, and non-dissipative effects.
Averaged residence times of stochastic motions in bounded domains
Two years ago, Blanco and Fournier (Blanco S. and Fournier R., Europhys. Lett. 61 (2003) 168) calculated the mean first exit time of a domain of a particle undergoing a randomly reoriented ballistic
Probability distributions for the run-and-tumble bacterial dynamics: An analogy to the Lorentz model
An analogy of the run-and-tumble process for bacterial motility with the Lorentz model of electron conduction is exploited to obtain analytical results for the intermediate scattering function in real space for two-dimensional systems.
