    "abstract": "We discuss the transition from a fully decoherent to a (quasi-)condensate\nregime in a harmonically trapped weakly interacting 1D Bose gas. By using\nanalytic approaches and verifying them against exact numerical solutions, we\nfind a characteristic crossover temperature and crossover atom number that\ndepend on the interaction strength and the trap frequency. We then identify the\nconditions for observing either an interaction-induced crossover scenario or\nelse a finite-size Bose-Einstein condensation phenomenon characteristic of an\n\\textit{ideal} trapped 1D gas.",
