#FieldTheory
"We call it ‘field theory’.
The notion of ‘fields’ was originally developed by physicists such as Newton, Michael Faraday, Richard Feynman and others. In physics, the concept has been used to explain gravity, electromagnetism, and particle interactions in quantum theory. But fields have also been used in biology to explain the development of living things. In the mid-20th century, the Austrian biologist Paul Weiss proposed that, within an embryo, large ‘morphogenetic fields’ directed the behaviour of cells inside them. Together, these pioneers in physics and biology showed how objects in the Universe can be directed by often-invisible and large-scale external structures. Our version of field theory takes this as its starting point."

山下真由子 京都大学理学部数学教室准教授の学歴が超すごい。
どこがすごいかと言うと、超進学校桜蔭高校から通信制東京都立新宿山吹高等学校へ編入学卒業。数学オリンピックの勉強に専念したかったから、らしい。
大学中退(というか飛び級)。博士課程中退。東京大学から博士(数理科学)。
専門は代数トポロジーと場の理論。

@ekmiller Oh My Various Goddess Abstractions. This is so incredibly beautiful 😍
STDP reveals that timing reshapes connections.
This paper reveals how, and it's... musical.
The brain as an "instrument" takes on new meaning.

"We show that optical bias fields injected into multistable #optical systems enable a controllable source of #quantum #randomness, and we demonstrated this concept in an optical parametric oscillator (OPO). By injecting bias pulses with less than one #photon on average, we controlled the probabilities of the two possible OPO output states."

#SoftMatter 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…
#Microswimmer 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 #PDEs.
A #LinearStabilityAnalysis of these equations suggests that variations in concentration across the system don’t significantly affect emergent #phaseBehaviour. How then can we explain #experiments that show visible inhomogeneities in #microtubule–#kinesin mixtures, for instance?
With increasing activity, we move away from the quiescent regime, past the onset of #SpontaneousFlow, and deeper into the active phase, where #nonlinearities become more important. What role do concentration inhomogeneities play here?
We investigated these questions, taking advantage of the #openSource #Dedalus #spectral framework to simulate the full nonlinear time evolution. This led us to predict a #novel regime of #spontaneous #microphaseSeparation 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 #nematic order. As a result, domains reach a characteristic size that decreases with increasing activity.
This regime is one part of the #PhaseDiagram we mapped out. Along with our other findings, you can read all about it here!

#SoftMatter 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 #hydrodynamic behaviour of inhomogeneous #activeNematic gels (such as extensile bundles of #cytoskeletal filaments or suspensions of low #ReynoldsNumber swimmers) can be described by the time evolution of three coupled #PDEs.
Standard #ActiveGel #theory concludes, from a #LinearStabilityAnalysis of these equations, that fluctuations in concentration don’t significantly affect emergent #phaseBehaviour. However, this leaves #experimental #observations of visible inhomogeneities in #microtubule–#kinesin mixtures unexplained. As we move away from the passive (quiescent) regime, past the onset of #SpontaneousFlow, and deeper into the active phase, #nonlinearities become more important. What role do concentration inhomogeneities play here?
Alongside #analytic techniques, we used an in-house #MPI-parallel code developed within the #Dedalus #spectral framework to investigate. We predict a #novel regime of #spontaneous #microphaseSeparation 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 #nematic order. As a result, domains do not #coarsen past a typical size, which decreases with increasing activity. This regime is one part of the #PhaseDiagram we mapped out.

Hello! As I’m new both to #Mastodon and to the #QOTO instance, I’d like to make my #introductions here.
I’m Dom, a postgraduate researcher studying #CondensedMatter, in particular #SoftMatter, #ActiveMatter, #MolecularBiology, #CellBiology, #PhaseTransitions, and #ComplexSystems using the tools of #TheoreticalPhysics, #BioPhysics, #StatisticalPhysics, #FluidDynamics, #ComputationalPhysics, and #Simulation.
I’m working on a few projects at the moment. One addresses #universality in active #turbulence with #spectral techniques. Another predicts a new microphase separation regime in inhomogeneous active #nematics by simulating the coupled #CahnHilliard, #NavierStokes, and #BerisEdwards equations. In another project I’m developing a #FieldTheory of the #orderphobic effect, a nonspecific interaction between #transmembrane bodies anchored in a #lipid #bilayer.
I’m also interested in…

Pulling together research from areas ranging from biology to neuroscience to philosophy, Dr. Johnjoe McFadden author of Quantum Evolution , has published a theory on the nature of consciousness that, if found to be correct, will surely change the way we perceive ourselves and humanity as a whole.
