Discrete Kernel Preserving Model for 1D Electron-Optical Phonon Scattering
D Electron-Optical Phonon Scattering Discrete Kernel Preserving Model
2014/9/26
We investigate the discretization of of an electron-optical phonon scattering using
a nite volume method. The discretization is conservative in mass and is essentially
based on an energy point of v...
Designing Optical Fibers: Fitting the Derivatives of a Nonlinear Pde-Eigenvalue Problem
Symmetric Indefinite Eigenvalue Gradient Optical Fiber Design
2013/1/30
When trying to fit data to functions of the eigensystem of a pde-eigenvalue problem, such as Maxwell’s equation, numerical differentiation is ineffective and analytic gradients must be supplied. In ou...
Bose-Einstein condensates in optical lattices: mathematical analysis and analytical approximate formulae
Bose-Einstein condensates stability of ground states analytical approximate formulae repulsive or attractive interatomic interactions
2011/9/6
Abstract: We show that the Gross-Pitaevskii equation with cubic nonlinearity, as a model to describe the one dimensional Bose-Einstein condensates loaded into a harmonically confined optical lattice, ...
Nonlinear localized modes in dipolar Bose-Einstein condensates in optical lattices
Nonlinear localized modes dipolar Bose-Einstein condensates condensates optical lattices
2011/7/7
The modulational instability and discrete matter wave solitons in dipolar BEC, loaded into a deep optical lattice, are investigated analytically and numerically. The process of modulational instabilit...
Semianalytic theory of self-similar optical propagation and mode locking using a shape-adaptive model pulse
adaptive model pulse Semianalytic theory self-similar optical propagation mode locking
2011/7/7
A semianalytic theory for the pulse dynamics in similariton amplifiers and lasers is presented, based on a model pulse with adaptive shape. By changing a single parameter, this test function can be co...
We exhibit a static, cylindrically symmetric, exact solution to the Euler-Heisenberg eld
equations (EHFE) and prove that its e ective geometry contains (optical) black holes. It
is conjectured that...
Orbit determination of space objects based on sparse optical data
orbit determination space debris
2011/3/4
While building up a catalog of Earth orbiting objects, if the available optical observations
are sparse, not deliberate follow ups of specific objects, no orbit determination is possible
without pre...
Dynamic synchronization of a time-evolving optical network of chaotic oscillators
Dynamic synchronization chaotic oscillators
2010/12/28
Dynamic synchronization of a time-evolving optical network of chaotic oscillators.
Dynamics of poles with position-dependent strengths and its optical analogues
Vortex dynamics complex variable strengths Snell’s law geometric optics hybrid systems
2010/12/3
Dynamics of point vortices is generalized in two ways: first by making the strengths complex, which allows for sources and sinks in superposition with the usual vortices, second by making them functio...
Comments on: "Optical solitons in a parabolic law media with fourth order dispersion"[Appl. Math. Comput. 208(2009)209-302]
Optical solitons parabolic law media fourth order dispersion
2010/4/6
Biswas and Milovic[Appl. Math. Comput.208(2009)209-302] have found the optical one-soliton solutions of a fourth order dispersive cubic-quintic nonlinear Schr\"odinger equation. In this comment, we fi...
Filamentation processes and dynamical excitation of light condensates in optical media with competing nonlinearities
dynamical excitation light condensates optical media competing nonlinearities
2010/4/2
We analyze both theoretically and by means of numerical simulations the phenomena of filamentation and dynamical formation of self-guided nonlinear waves in media featuring competing cubic and quintic...
Time neural network minimum distance classifier and its application to optical character recognition problem
neural network classifier minimum distance classification
2010/9/13
We propose a special neural network model, NNC, (Neural Network Classifier), which with a classification problem of l classes C1,C2, ...,Cl, classifies an unknown vector to one class using a minimum d...
Arc perturbation algorithms for optical network design
Graph algorithms optical network optimization
2010/9/15
Today’s network planners are faced with the challenge to design highly complex optical networks. In this paper we describe and study the performance of two new combinatorial algorithms based on the lo...
