have just published the results of a project that Renato Assante, Davide Marenduzzo, Alexander Morozov, and I recently worked on together! What did we do and what’s new? Briefly…

suspensions behave in a similar way to fluids containing kinesin and microtubules. Both systems can be described by the same system of three coupled nonlinear .

A of these equations suggests that variations in concentration across the system don’t significantly affect emergent . How then can we explain that show visible inhomogeneities in – mixtures, for instance?

With increasing activity, we move away from the quiescent regime, past the onset of , and deeper into the active phase, where become more important. What role do concentration inhomogeneities play here?

We investigated these questions, taking advantage of the framework to simulate the full nonlinear time evolution. This led us to predict a regime of into active (nematically ordered) and passive domains.

Active flow arrests macrophase separation in this regime, counteracting domain coarsening due to thermodynamic coupling between active matter concentration and order. As a result, domains reach a characteristic size that decreases with increasing activity.

This regime is one part of the we mapped out. Along with our other findings, you can read all about it here!

have just published the results of a project that Renato Assante, Davide Marenduzzo, Alexander Morozov, and I recently worked on together! What did we do and what’s new? Briefly…

The behaviour of inhomogeneous gels (such as extensile bundles of filaments or suspensions of low swimmers) can be described by the time evolution of three coupled .

Standard concludes, from a of these equations, that fluctuations in concentration don’t significantly affect emergent . However, this leaves of visible inhomogeneities in – mixtures unexplained. As we move away from the passive (quiescent) regime, past the onset of , and deeper into the active phase, become more important. What role do concentration inhomogeneities play here?

Alongside techniques, we used an in-house -parallel code developed within the framework to investigate. We predict a regime of into active (nematically ordered) and passive domains. In this regime, active flow arrests macrophase separation, which is itself driven by the thermodynamic coupling between active matter concentration and order. As a result, domains do not past a typical size, which decreases with increasing activity. This regime is one part of the we mapped out.

Hello! As I’m new both to and to the instance, I’d like to make my here.

I’m Dom, a postgraduate researcher studying , in particular , , , , , and using the tools of , , , , , and .

I’m working on a few projects at the moment. One addresses in active with techniques. Another predicts a new microphase separation regime in inhomogeneous active by simulating the coupled , , and equations. In another project I’m developing a of the effect, a nonspecific interaction between bodies anchored in a .

I’m also interested in…
