Symmetry breaking phase transitions occurring in the early Universe are expected to leave behind long-lived topologically stable structures such as monopoles, strings or domain walls1–6. Here I discuss the analogy between cosmological strings and vortex lines in the superfluid, and suggest a cryogenic experiment which tests key elements of the cosmological scenario for string formation. In a superfluid obtained through a rapid pressure quench, the phase of the Bose condensate wavefunction—the… Expand
Laboratory simulation of cosmic string formation in the early Universe using superfluid 3He
TOPOLOGICAL defects in the geometry of space–time (such as cosmic strings) may have played an important role in the evolution of the early Universe, by supplying initial density fluctuations whichExpand

TLDR
The paradigmatic KZM provides a framework to describe the dynamics across a continuous phase transition and inherits an imprint of universality, scaling with the quench time as t̂ = ðτ0τQÞ and eðtÞ ’ t=τQ, where τQ is theQuench time in which the transition is crossed. Expand
