Phys. Rev. Lett. 92, 163201 (2004) [4 pages]Coherence Properties of Guided-Atom InterferometersReceived 10 September 2003; published 21 April 2004 We present a detailed theoretical investigation of the coherence properties of beam splitters and Mach-Zehnder interferometers for guided neutral atoms. We show that such a setup permits coherent wave packet splitting and leads to the appearance of interference fringes for both single-mode and thermal input states, evidencing thus the robustness of the interferometer. © 2004 The American Physical Society URL:
