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
Vortex formation in neutron-irradiated superfluid 3He as an analogue of cosmological defect formation
TOPOLOGICAL defects formed during a rapid symmetry-breaking phase transition in the early Universe1,2 could be responsible for seeding large-scale structure, for the anisotropy of the microwaveExpand
Generation of defects in superfluid 4He as an analogue of the formation of cosmic strings
ALTHOUGH the birth of the Universe is inaccessible to experimental study, aspects of cosmological theories can nonetheless be explored in the laboratory. Tiny inhomogeneities in the mix of particlesExpand
Cosmological Experiments in Superfluids and Superconductors
Evolution of the order parameter in condensed matter analogues of cosmological phase transitions is discussed. It is shown that the density of the frozen-out topological defects is set by theExpand
Initial monopole density in an inflationary Universe

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

Fluctuations and lambda phase transition in liquid helium
Abstract A general dynamical scaling theory of phase transitions is established by exploiting the absence of a characteristic length in an extended system at its phase transition. This similarityExpand
Vortex Line Models for Dual Strings
We call attention to the possibility of constructing field theories for the dual string. As an example, we show that a Higgs type of Lagrangian allows for vortex-line solutions, in analogy with theExpand
