Phys. Rev. Lett. 94, 060404 (2005) [4 pages]Direct Imaging of Spatially Modulated Superfluid Phases in Atomic Fermion SystemsReceived 9 September 2004; published 18 February 2005 It is proposed that the spatially modulated superfluid phase, or the Fulde-Ferrell-Larkin-Ovchinnikov state could be observed in resonant fermion atomic condensates which are realized recently. We examine optimal experimental setups to achieve it by solving the Bogoliubov–de Gennes equation for both idealized one-dimensional and realistic three-dimensional cases. The spontaneous modulation of this superfluid is shown to be directly imaged as the density profiles either by optical absorption or by Stern-Gerlach experiments. © 2005 The American Physical Society URL:
