Phys. Rev. Lett. 83, 1715–1718 (1999)Extended Parametric Resonances in Nonlinear Schrödinger SystemsReceived 15 March 1999; published in the issue dated 30 August 1999 We study an example of exact parametric resonance in an extended system ruled by nonlinear partial differential equations of nonlinear Schrödinger type. It is also conjectured how related models not exactly solvable should behave in the same way. The results have applicability in recent experiments in Bose-Einstein condensation and to classical problems in nonlinear optics. © 1999 The American Physical Society URL:
