Our @natphys.nature.com paper is now out!
We find that defect creation & annihilation in bacteria and cells collectives spontaneously break mirror symmetry—unpredicted by active nematic theory.

Topological defects dynamically act as nucleation sites for phase separation in quantum systems—a universal mechanism revealed through holographic simulations of symmetry breaking and nonequilibrium dynamics.
