Wannier functions analysis of the nonlinear Schrödinger equation with a periodic potential
Walter's function nonlinear schrodinger equation periodic vector lattice
2014/12/29
In the present paper we use the Wannier function basis to construct lattice approximations of the nonlinear Schrödinger equation with a periodic potential. We show that the nonlinear Schrödi...
Discrete Klein–Gordon models with static kinks free of the Peierls–Nabarro potential
Gordon type model nonlinear klein discretization static kink lattice the discrete model
2014/12/25
For the nonlinear Klein–Gordon type models, we describe a general method of discretization in which the static kink can be placed anywhere with respect to the lattice. These discrete models are, there...

Discrete nonlinear schrodinger equation nonlinear discrete fixed discrete soliton
2014/12/25
We derive a class of discrete nonlinear Schrödinger (DNLS) equations for general polynomial nonlinearity whose stationary solutions can be found from a reduced two-point algebraic problem. It is ...

Model of condensate hyperfine status the mixture
2014/12/25
We introduce a model motivated by studies of Bose–Einstein condensates (BECs) trapped in double-well potentials. We assume that a mixture of two hyperfine states of the same atomic species is loaded i...

Mechanical systems linear geometric properties nonlinear dynamic equations
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...
Controlling the transverse instability of dark solitons and nucleation of vortices by a potential barrier
Inhibition of dark soliton stripes instability two-dimensional condensate one dimensional structure
2014/12/24
We study possibilities to suppress the transverse modulational instability (MI) of dark-soliton stripes in two-dimensional Bose-Einstein condensates (BEC’s) and self-defocusing bulk optical waveguides...
Potential theory of Schrödinger operator based on fractional Laplacian

2009/9/22
We develop potential theory of Schrdinger operators
based on fractional Laplacian on Euclidean spaces of arbitrary dimension.
We focus on questions related to gaugeability and existence of

The Distribution of Time Spent by a Standard Excursion Above a Given Level, with Applications to Ring Polymers near a Discontinuity in Potential
Standard Brownian Excursions Brownian Bridges Ring Polymers End-Attached Polymers
2009/5/8
The law for the time tau_{a} spent by a standard Brownian excursion above a given level a>0 is found using Ito excursion theory. This is achieved by conditioning the excursion to have exactly one mark...
Large Deviations and Quasi-Potential of a Fleming-Viot Process
Fleming-Viotprocess largedeviations quasi-potential
2009/4/29
The large deviation principle is established for the Fleming-Viot process with neutral mutation when the process starts from a point on the boundary. Since the diffusion coefficient is degenerate on t...
