Tracking phase synchronization between flagella in the time-frequency domain resolves photophobic response
Lucas Federspiel, Jorge Arrieta, Marco Polin +2
The unicellular microalga Chlamydomonas reinhardtii (CR) is well known for its bi-flagellated swimming in response to light stimuli. This work aims to study the resynchronization o…
Geometric phase of spheroidal particles in a fluid flow and its control
Jorge Arrieta, Julyan H. E Cartwright, Oreste Piro +1
We investigate the dynamics of spheroids immersed in the journal bearing flow subject to a contractible non-reciprocal loop. We show how geometric phases appear not only in the pos…
Photo-bioconvection: towards light-control of flows in active suspensions
Armand Javadi, Jorge Arrieta, Idan Tuval +1
The persistent motility of the individual constituents in microbial suspensions represents a prime example of so-called active matter systems. Cells consume energy, exert forces an…
On the flow separation mechanism in the inverse Leidenfrost regime
J. Arrieta, A. Sevilla
The inverse Leidenfrost regime occurs when a heated object in relative motion with a liquid is surrounded by a stable vapour layer, drastically reducing the hydrodynamic drag at la…
Turbulence induces clustering and segregation of non-motile, buoyancy-regulating phytoplankton
Matteo Borgnino, Jorge Arrieta, Guido Boffetta +2
Turbulence plays a major role in shaping marine community structure as it affects organism dispersal and guides fundamental ecological interactions. Below oceanographic mesoscale d…
Light-Control of Localised Photo-Bio-Convection
Jorge Arrieta, Marco Polin, Ramón Saleta-Piersanti +1
Microorganismal motility is often characterised by complex responses to environmental physico-chemical stimuli. Although the biological basis of these responses is often not well u…
Phototaxis beyond turning: persistent accumulation and response acclimation of the microalga Chlamydomonas reinhardtii
Jorge Arrieta, Ana Barreira, Maurizio Chioccioli +2
Phototaxis is an important reaction to light displayed by a wide range of motile microorganisms. Flagellated eukaryotic microalgae in particular, like the model organism Chlamydomo…
Geometric Mixing, Peristalsis, and the Geometric Phase of the Stomach
Jorge Arrieta, Julyan H. E. Cartwright, Emmanuelle Gouillart +3
Mixing fluid in a container at low Reynolds number - in an inertialess environment - is not a trivial task. Reciprocating motions merely lead to cycles of mixing and unmixing, so c…
