TL;DR: In this article, the authors investigate the formation of the matter rogue wave in Bose-Einstein condensates with attractive interatomic interaction analytically and numerically and show that the formation is mainly due to the accumulation of energy and atoms toward to its central part; the decay rate of the atomic number can be effectively controlled by modulating the trapping frequency of external potential.
Abstract: We investigate the matter rogue wave in Bose-Einstein Condensates with attractive interatomic interaction analytically and numerically. Our results show that the formation of rogue wave is mainly due to the accumulation of energy and atoms toward to its central part; Rogue wave is unstable and the decay rate of the atomic number can be effectively controlled by modulating the trapping frequency of external potential. The numerical simulation demonstrate that even a small periodic perturbation with small modulation frequency can induce the generation of a near-ideal matter rogue wave. We also give an experimental protocol to observe this phenomenon in Bose-Einstein Condensates.

TL;DR: In this article, the effects of the group velocity dispersion coefficient and the fourth-order nonlinear Schrodinger equation on the first-order and second-order rogue wave solutions were analyzed.
Abstract: In this paper, investigation is made on the coupled variable-coefficient fourth-order nonlinear Schrodinger equations, which describe the simultaneous propagation of optical pulses in an inhomogeneous optical fiber. Via the generalized Darboux transformation, the first- and second-order rogue wave solutions are constructed. Based on such solutions, effects of the group velocity dispersion coefficient and the fourth-order dispersion coefficient on the rogue waves are graphically analyzed. The first-order rogue waves with the eye-shaped distribution, the interactions between the first-order rogue waves with solitons, and the second-order rogue waves with one highest peak and with the triangular structure are displayed. When the value of the group velocity dispersion coefficient or the fourth-order dispersion increases, range of the first-order rogue wave increases. Composite rogue waves are obtained, where the temporal separation between two adjacent rogue waves can be changed if we adjust the group velocity dispersion coefficient and fourth-order dispersion coefficient. Periodic rogue waves are presented. Periods of such rogue waves decrease with the periods of the group-velocity dispersion and fourth-order dispersion coefficient decreasing.

TL;DR: In this article, the existence of a giant breather on the surface of deep water was demonstrated by numerical simulation of the fully nonlinear water equations, which can explain the appearance of freak waves.
Abstract: Numerical simulation of the fully nonlinear water equations demonstrates the existence of giant breathers on the surface of deep water. The numerical analysis shows that this breather (or soliton of envelope) does not loose energy. The existence of such a breather can explain the appearance of freak waves.

TL;DR: It is observed that rogue events do not necessarily appear without a warning, but are often preceded by a short phase of relative order, which sheds some new light on the fascinating phenomenon of rogue waves.
Abstract: Analysis of experimental data from multi-filament, oceanic and fiber optic rogue wave systems show that rogue waves are often preceded by a short ordered phase, providing a method to predict their occurrence.
