Phys. Rev. Lett. 103, 210402 (2009) [4 pages]Anderson Localization of SolitonsReceived 2 July 2009; revised 2 November 2009; published 17 November 2009 At low temperature, a quasi-one-dimensional ensemble of atoms with an attractive interaction forms a bright soliton. When exposed to a weak and smooth external potential, the shape of the soliton is hardly modified, but its center-of-mass motion is affected. We show that in a spatially correlated disordered potential, the quantum motion of a bright soliton displays Anderson localization. The localization length can be much larger than the soliton size and could be observed experimentally. © 2009 The American Physical Society URL:
