    "abstract": "For a rather general class of scenarios, sweeping through a zero-temperature\nphase transition by means of a time-dependent external parameter entails\nuniversal behavior: In the vicinity of the critical point, excitations behave\nas quantum fields in an expanding or contracting universe. The resulting\neffects such as the amplification or suppression of quantum fluctuations (due\nto horizon crossing, freezing, and squeezing) including the induced spectrum\ncan be derived using the curved space-time analogy. The observed similarity\nentices the question of whether cosmic inflation itself might perhaps have been\nsuch a phase transition. PACS: 73.43.Nq, 04.62.+v, 98.80.Cq, 04.80.-y.",
