Beyond the Markovian limit: Exact solutions for active motion in a power-law viscoelastic bath
Mintu Karmakar, Jure Dobnikar, Ignacio Pagonabarraga
Active particles from bacteria to synthetic microswimmers often navigate viscoelastic media with complex relaxation dynamics. The classical active Brownian model that assumes insta…
Universal transport of active colloids with sensory delay in motility landscapes
Adrià Garcés, Ueli Töpfer, Lucio Isa +2
We experimentally, numerically and analytically explore the diffusive transport of active colloidal particles with sensory delay, navigating motility landscapes in which the self-p…
Dynamics of O(2) excitations in a non-reciprocal medium
Ylann Rouzaire, Daniel JG Pearce, Ignacio Pagonabarraga +1
We investigate emergent dynamics due to non-reciprocity in the model. The lattice XY model, where non-reciprocity stems from vision cone like couplings, can be des…
Is the active suspension in a complex viscoelastic fluid more chaotic or more ordered?
Yuan Zhou, Qingzhi Zou, Ignacio Pagonabarraga +2
The habitat of microorganisms is typically complex and viscoelastic. A natural question arises: Do polymers in a suspension of active swimmers enhance chaotic motion or promote ori…
Protocol to evaluate the viscoelastic response of a polymer suspension to an active agent via oscillatory shear rheometry
Kai Qi, Qingzhi Zou, Ignacio Pagonabarraga
Microorganisms inhabit viscoelastic environments, where their locomotion can deform polymers and trigger local complex viscoelastic responses. However, a systematic approach to qua…
Hydrodynamic Mechanism of Colloidal Propulsion through Momentum Exchange
Javier Diaz, Ignacio Pagonabarraga, Carles Calero
Propulsion of colloidal particles due to momentum transfer from localized surface reactions is investigated by solving the exact unsteady Stokes equation. We model the effect of su…
Sorting of binary active-passive mixtures in designed microchannels
Horacio Serna, C. Miguel Barriuso G., Ignacio Pagonabarraga +2
Mixtures of active and passive particles are ubiquitous at the microscale. Many essential microbial processes involve interactions with dead or immotile cells or passive crowders.…
Unravel the rotational and translational behavior of a single squirmer in flexible polymer solutions at different Reynolds numbers
Yuan Zhou, Kai Qi, Marco De Corato +2
Microorganisms thrive in complex environments and their behavior in fluids holds significant importance for various medical and industrial applications. By conducting Lattice Boltz…
Colloidal Model for Investigating Optimal Efficiency in Weakly Coupled Ratchet Motors
José Martín-Roca, Laura Izquierdo-Solís, Fernando Martínez-Pedrero +3
We investigate the transport of superparamagnetic colloidal particles along self-assembled tracks using a periodically applied magnetic field as a model for ratchet-like mechanisms…
Sedimentation and structure of squirmer suspensions under gravity
C. Miguel Barriuso G., Horacio Serna, Ignacio Pagonabarraga +1
The effect of gravity on the collective motion of living microswimmers, such as bacteria and micro-algae, is pivotal to unravel not only bio-convection patterns but also the settli…
Active droplets controlled by enzymatic reactions
Jacques Fries, Javier Diaz, Marie Jardat +3
The formation of condensates is now considered as a major organization principle of eukaryotic cells. Several studies have recently shown that the properties of these condensates a…
Curvature induces and enhances transport of spinning colloids through narrow channels
Eric Cereceda-López, Marco De Corato, Ignacio Pagonabarraga +3
The effect of curvature and how it induces and enhances the transport of colloidal particles driven through narrow channels represent an unexplored research avenue. Here we combine…
Active particles confined in deformable droplets
Javier Diaz, Ignacio Pagonabarraga
Active particles under soft confinement such as droplets or vesicles present intriguing phenomena, as collective motion emerges alongside the deformation of the environment. A mode…
Lattice Boltzmann simulation of deformable fluid-filled bodies: progress and perspectives
