E, Melville, v. 82, e057601, 2010.e- 1550-2376http://repositorio.bc.ufg.br/handle/ri/15282In this paper we present analytical breather solutions of the three-dimensional nonlinear generalized Gross- Pitaevskii equation. We use an Ansatz to reduce the three-dimensional equation with space- and timedependent coefficients into a one-dimensional equation with constant coefficients. The key point is to show that both the space- and time-dependent coefficients of the nonlinear equation can contribute to modulate the breather excitations. We briefly discuss the experimental feasibility of the results in Bose-Einstein condensates.engAcesso AbertoArtigo10.1103/PhysRevE.82.057601
