The Analogue Gravity program has had considerable success recently, with ultracold gases playing a particularly prominent role as a system in which quantum aspects of field theory in curved spacetime can be explored. In this talk, I will present the analogy between a modulated 1D condensate and the preheating stage of cosmology, whereby a large number of quasiparticle pairs are excited out of vacuum.
