Magnetic active matter across scales
Francisca Guzmán-Lastra, Margaret Rosenberg, Marco Musacchio +2
Magnetic interactions provide a versatile and powerful tool for controlling and organizing active matter, where individual units continuously consume energy to drive autonomous mot…
Emergence of beating in a magnetic flagellum consisting of active bots
Francisca Guzmán-Lastra, Daniel Hernández, Nicolás Quintriqueo +2
We investigate the emergence of flagellar beating in chains of magnetic self--propelled particles (MSPPs) built from centimeter--scale vibrating robots (Hexbugs) with embedded neod…
Collective phases in overdamped magnetic self-propelled spherocylinders
Francisca Guzmán-Lastra, Néstor Sepúlveda
We study the collective dynamics of self-propelled spherocylinders carrying magnetic dipole moments in two dimensions. Magnetic interactions are modeled as two opposite monopoles $…
Dynamics of magnetic self-propelled particles in a harmonic trap
Pamela Muñoz Obreque, Oscar Garrido, Diego Romero +2
Artificial active particles, exemplified by Hexbugs (HB), serve as valuable tools for investigating the intricate dynamics of active matter systems. Leveraging their stochastic mot…
Floating active carpets drive transport and aggregation in aquatic ecosystems
Gabriel Aguayo, Arnold J. T. M. Mathijssen, Hugo N. Ulloa +2
Communities of swimming microorganisms often thrive near liquid-air interfaces. We study how such `active carpets' shape their aquatic environment by driving biogenic transport in…
Macroscopic bioinspired magnetic active matter and the physical limits of magnetotaxis
Néstor Sepúlveda, Francisca Guzmán-Lastra, Miguel Carrasco +4
Magnetotactic bacteria (MTB) are endowed with an exquisite orientation mechanism allowing them to swim along the geomagnetic field lines. This mechanism consists of a chain of bio-…
Membrane penetration and trapping of an active particle
Abdallah Daddi-Moussa-Ider, Segun Goh, Benno Liebchen +6
The interaction between nano- or micro-sized particles and cell membranes is of crucial importance in many biological and biomedical applications such as drug and gene delivery to…
Nutrient transport driven by microbial active carpets
Arnold J. T. M. Mathijssen, Francisca Guzmán-Lastra, Andreas Kaiser +1
We demonstrate that active carpets of bacteria or self-propelled colloids generate coherent flows towards the substrate, and propose that these currents provide efficient pathways…
Fission and fusion scenarios for magnetic microswimmer clusters
Francisca Guzmán-Lastra, Andreas Kaiser, Hartmut Löwen
Fission and fusion processes of particles clusters occur in many areas of physics and chemistry from subnuclear to astronomic length scales. Here we study fission and fusion of mag…
