Dynamical-state switching controls active microrod navigation in porous media
Ana Cazorla, Maria L. Jimenez, Raul A. Rica-Alarcon +2
Adaptive search and travel strategies enable biological swimmers to explore complex environments, but remain difficult to encode in minimal synthetic microswimmers. Here, we unveil…
Active Colloids in Harmonic Optical Potentials
Ivo Buttinoni, Lorenzo Caprini, Laura Alvarez +2
We study the motion of active patchy colloids in an optical trap using experiments, theory and numerical simulations. To achieve isotropic and harmonic confinement, we prototype mi…
Self-propelling colloidal finite state machines
Steven van Kesteren, Laura Alvarez, Silvia Arrese-Igor +2
Endowing materials with physical intelligence holds the key for a progress leap in robotic systems. In spite of the growing success for macroscopic devices, transferring these conc…
When bigger is faster: a self-van Hove analysis of the enhanced self-diffusion of non-commensurate guest particles in smectics
M. Paul Lettinga, Laura Alvarez, Olivera Korculanin +1
We investigate the anomalous dynamics in smectic phases of short host rods where, counter-intuitively, long guest rod-shaped particles diffusive faster than the short host ones, du…
Active Brownian motion with orientation-dependent motility: theory and experiments
Alexander R. Sprenger, Miguel Angel Fernandez-Rodriguez, Laura Alvarez +3
Combining experiments on active colloids, whose propulsion velocity can be controlled via a feedback loop, and theory of active Brownian motion, we explore the dynamics of an overd…
Feedback-Controlled Active Brownian Colloids with Space-Dependent Rotational Dynamics
Miguel Angel Fernandez-Rodriguez, Fabio Grillo, Laura Alvarez +4
The non-thermal nature of self-propelling colloids offers new insights into non-equilibrium physics. The central mathematical model to describe their trajectories is active Brownia…
Fast Diffusion of Long Guest Rods in a Lamellar Phase of Short Host Particles
Laura Alvarez, M. Paul Lettinga, Eric Grelet
We investigate the dynamic behavior of long guest rod-like particles immersed in liquid crystalline phases formed by shorter host rods, tracking both guest and host particles by fl…
