Phase transitions are ubiquitous in nature, and can be arranged
into universality classes such that systems having unrelated micro-
scopic physics show identical scaling behaviour near the critical
point. One prominent universal element of many continuous
phase transitions is the spontaneous formation of topological
defects during a quench through the critical point1­3
. The micro-
scopic dynamics of defect formation in such transitions are gen-
erally difficult to investigate, particularly for superfluids4­7
However, Bose­Einstein condensates (BECs) offer unique experi-
