Coherent inflationary dynamics for Bose–Einstein condensates crossing a quantum critical point
Quantum phase transitions, transitions between many-body ground states, are of extensive interest in research ranging from condensed-matter physics to cosmology 1 – 4 . Key features of the phase transitions include a stage with rapidly growing new order, called inflation in cosmology 5 , followed by...

. We report the observation of coherent inflationary dynamics across a quantum critical point in driven Bose–Einstein condensates. The inflation manifests in the exponential growth of density waves and populations in well-resolved momentum states. After the inflation stage, extended coherent dynamics is evident in both real and momentum space. We present an intuitive description of the quantum critical dynamics in our system and demonstrate the essential role of phase fluctuations in the formation of topological defects.
An ultracold quantum gas experiment shows that, when it crosses the many-body phase transition, the original ground state can evolve coherently into the new emergent phase, reflecting the initial global coherence presented in the system. |
