A new experiment has been performed to study the formation of topological defects (quantized vortices) during rapid quenches of liquid 4He through the superfluid transition, with particular care taken to minimise vortex creation via conventional hydrodynamic flow processes. It is found that the generated vortices, if any, are being produced at densities at least two orders of magnitude less than might be expected on the basis of the Kibble-Zurek mechanism.

  1. Phase separation seeded by Z2 and U(1) topological defects from holography

    hep-th 2026-05 unverdicted novelty 6.0

    Holographic simulations demonstrate that Z2 and U(1) topological defects universally seed phase separation, with cores expanding into domains under a double-quench protocol.
