High-order-mode soliton structures in two-dimensional lattices with defocusing nonlinearity
Discrete soliton self-focusing defocusing nonlinear dipole the structure of vortex solitons
2014/12/25
While fundamental-mode discrete solitons have been demonstrated with both self-focusing and defocusing nonlinearity, high-order-mode localized states in waveguide lattices have been studied thus far o...

Two-dimensional discrete nonlinear schrodinger nonlinear equation the rotating reference frame bose-einstein condensate
2014/12/25
We introduce a two-dimensional discrete nonlinear Schrödinger (DNLS) equation with self-attractive cubic nonlinearity in a rotating reference frame. The model applies to a Bose-Einstein condensat...

2014/12/25
We demonstrate a possibility to generate localized states in effectively one-dimensional Bose-Einstein condensates with a negative scattering length in the form of a dark soliton in the presence of an...
Structure and stability of two-dimensional Bose-Einstein condensates under both harmonic and lattice confinement
Two-dimensional condensate the harmonic potential optical lattice
2014/12/25
In this work, we study two-dimensional Bose–Einstein condensates confined by both a cylindrically symmetric harmonic potential and an optical lattice with equal periodicity in two orthogonal direction...

2014/12/24
We present an experimentally realizable, simple mechanical system with linear interactions whose geometric nature leads to nontrivial, nonlinear dynamical equations. The equations of motion are derive...

2013/6/17
We introduce a novel class of rotation invariants of two dimensional curves based on iterated integrals. The invariants we present are in some sense complete and we describe an algorithm to calculate ...

The paper proposes Monte Carlo algorithms for
the computation of the information rate of two-dimensional
source / channel models. The focus of the paper is on binary-input
channels with constraints...
ON THE STRONG LAWS OF LARGE NUMBERS FOR TWO-DIMENSIONAL ARRAYS OF BLOCKWISE INDEPENDENT AND BLOCKWISE ORTHOGONAL RANDOM VARIABLES
Blockwise independent random variables two-dimensional arrays of random variables
2009/9/18
In this paper we obtain the conditions of the strong

which are blockwise independent and blockwise orthogonal. Some
well-known re...
