In the end, they do an interdiscplinary master thesis and go out into the world as a computational scientist fit for the 2020s, where a leading question is how we combine physics based and data based modelling.

The one program is for physicists and mathematicians with a strong background in mathematics and you can focus on , or computational geosciences:

🎉 Congratulations to Martin Trappe & Ryan Chisholm for their paper in Nature Communications!

They used density functional theory from physics to make spatial ecosystem models. This general computational framework makes predictions that are as good as specialised models on systems from predatory microbes to territorial flies to trees

Has anyone here used "Meep" for photonics simulation? I am looking into open source electromagnetics software.

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…

Since we're all doing and I just put all this thought into my bio, I'm going to cheat a bit:

he/him
Software, Sailing, Science and assorted Geekery in the US Pacific Northwest.
by day, by night. and when I can.

Some professional interests:

Gibt es hier PhysikerInnen oder InformatikerInnen oder hilfreiche Geister aus der -bubble?
Ich hätte eine Frage zum Studium.
Wo kann man vernünftig einen Master in Physik mit Schwerpunkt machen?

Frage für einen Neffen, der gerade über seiner Bachelor Arbeit schwitzt…
