    "abstract": "The linewidth of an atom laser can be limited by excitation of higher energy\nmodes in the source Bose-Einstein condensate, energy shifts in that condensate\ndue to the atomic interactions, or phase diffusion of the lasing mode due to\nthose interactions. The first two are effects that can be described with a\nsemiclassical model, and have been studied in detail for both pumped and\nunpumped atom lasers. The third is a purely quantum statistical effect, and has\nbeen studied only in zero dimensional models. We examine an unpumped atom laser\nin one dimension using a quantum field theory using stochastic methods based on\nthe truncated Wigner approach. This allows spatial and statistical effects to\nbe examined simultaneously, and the linewidth limit for unpumped atom lasers is\nquantified in various limits.",
