In the late 1960s, physicists argued that singularities might be surrounded by a region of churning chaos, where space and time haphazardly grow and shrink. It was dubbed a “Mixmaster universe,” after a line of kitchen appliances. https://buff.ly/4kaLDWZ

Percolation thresholds and connectivity in quantum networks
We study entanglement percolation in qubit-based planar quantum network models of arbitrary topology, where neighboring nodes are initially connected by pure states with quenched disorder in their ent...

🎉 Happy to share that my longest Ph.D. project, “A fully-integrated lattice Boltzmann method for fluid–structure interaction”, is online! We develop a fully Eulerian method to simulate many squishy solids in fluids. (1/3)

What if… spontaneous neural activity 🧠 reflects the baseline rumblings of a brainwide dynamical system initialized for learning? We find that the rumblings have macroscopic properties like those emerging from linear symmetric, critical systems 🧵 #neuroscience #neuroAI www.biorxiv.org/content/10.1...

1/6 🧪 Preprint-Alert!
We looked at how molecules move across phase boundaries, e.g., in liquid droplets, taking into account that chemical potentials inside and outside the boundary can be different!

This unites recent work with stuff from the 60s and has cool consequences 👇

Transport kinetics across interfaces between coexisting liquid phases
We investigate the kinetics of material transport across interfaces in phase-separated mixtures. Using non-equilibrium thermodynamics we derive the interfacial kinetics, describing the movement of the...

🚨Hyped to share our new article in @natureportfolio.bsky.social! We show that crocodile head scales develop from compressive folding that arises from constrained skin growth 🐊🔬
Really proud of this one - it's cool 😎

Fascinating 🧵!!
We learn in school about the distinctive shapes of each of our body’s organs, but how did that arise? Organs self-assemble, as individual cells change shape and move in coordinated ways, sometimes with multiple cell /tissue types shaping one another 1/n 🧪

This is beautiful 😄
Mix two motors of opposite polarity with microtubules and they will partition space !
Microtubules will get organized in polar and active barriers, sorting the two motors in separated domains, leading to the emergence of a new type of patterns.
