Renormalization-group and numerical analysis of a noisy Kuramoto-Sivashinsky equation in 1+1 dimensions
K. Ueno, H. Sakaguchi, M. Okamura
The long-wavelength properties of a noisy Kuramoto-Sivashinsky (KS) equation in 1+1 dimensions are investigated by use of the dynamic renormalization group (RG) and direct numerica…
Scattering of Solitons and Dark Solitons by Potential Walls in the Nonlinear Schroedinger Equation
Hidetsugu Sakaguchi, Mitsuaki Tamura
Scattering of solitons and dark solitons by potential walls is studied in the nonlinear Schroedinger equation under various conditions. We investigate the conditions under which so…
Resonant nonlinearity management for nonlinear-Schrödinger solitons
Hidetsugu Sakaguchi, Boris A. Malomed
We consider effects of a periodic modulation of the nonlinearity coefficient on fundamental and higher-order solitons in the one-dimensional NLS equation, which is an issue of dire…
Two-dimensional loosely and tightly bound solitons in optical lattices and inverted traps
H. Sakaguchi, B. A. Malomed
We study the dynamics of nonlinear localized excitations (solitons) in two-dimensional (2D) Bose-Einstein condensates (BECs) with repulsive interactions, loaded into an optical lat…
Scattering and Trapping of Nonlinear Schroedinger Solitons in External Potentials
H. Sakaguchi, M. Tamura
Soliton motion in some external potentials is studied using the nonlinear Schrödinger equation. Solitons are scattered by a potential wall. Solitons propagate almost freely or are…
