Condensed-matter physics: Surviving the transition
Kristian Helmerson1
Abstract
Observations of the birth of a superfluid have uncovered details of the microphysics of phase transitions. Whether these results can be used to model such transitions in the early Universe is an open question.
The spontaneous formation of topological defects — stable configurations of matter — is thought to accompany most continuous, non-equilibrium phase transitions in condensed-matter physics. But the study of the microscopic dynamics underlying the formation of such defects is a challenge, especially in superfluid transitions.
