CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe consider the existence and propagazione of nondiractive and nondispersive spatiotemporal optical wavepackets in nonlinear Kerr media. We report analytically and conrm numerically the properties of spatiotemporal dark line solitary wave solutions of the (2 + 1)D nonlinear Schrödinger equation (NLSE). Dark lines represent holes of light on a continuous wave background. Moreover, we consider nontrivialweb patterns generated under interactions of dark line solitarywaves,which give birth to dark X solitary waves. These solitary waves are derived by exploiting the connection between the NLSE and a wellknown equation of hydrodynamics, namely the (2 + 1)D type II Kadomtsev-Petviashvili (KP-II) equation. This ending opens a novel path for the excitation and control of optical solitary waves, of hydrodynamic nature.

| Abstract: | We consider the existence and propagazione of nondiractive and nondispersive spatiotemporal optical wavepackets in nonlinear Kerr media. We report analytically and conrm numerically the properties of spatiotemporal dark line solitary wave solutions of the (2 + 1)D nonlinear Schrödinger equation (NLSE). Dark lines represent holes of light on a continuous wave background. Moreover, we consider nontrivialweb patterns generated under interactions of dark line solitarywaves,which give birth to dark X solitary waves. These solitary waves are derived by exploiting the connection between the NLSE and a wellknown equation of hydrodynamics, namely the (2 + 1)D type II Kadomtsev-Petviashvili (KP-II) equation. This ending opens a novel path for the excitation and control of optical solitary waves, of hydrodynamic nature. | |
