Variational approach to the modulational instability
Coupling nonlinear schrodinger equation the coupling disturbance amplitude condensed bose - Einstein
2014/12/29
We study the modulational stability of the nonlinear Schrödinger equation using a time-dependent variational approach. Within this framework, we derive ordinary differential equations (ODE’s) for...
Excited states in the Thomas–Fermi limit: a variational approach
Excited state condensate semi-classical Thomas Fermi extreme exclusion
2014/12/24
Excited states of Bose–Einstein condensates are considered in the semi-classical (Thomas- Fermi) limit of the Gross–Pitaevskii equation with repulsive inter-atomic interactions and a harmonic potentia...
Variational Approach to Yang--Mills Theory with non-Gaussian Wave Functionals
Yang--Mills Theory non-Gaussian Wave Functionals
2010/12/24
A general method for treating non-Gaussian wave functionals in quantum field theory is presented and applied to the Hamiltonian approach to Yang-Mills theory in Coulomb gauge in order to include a th...

Nonlinear Oscillators Variational formulation
2010/11/25
This paper presents a new approach for solving approximate analytical higher order solutions for strong nonlinear Duffing oscillators with cubic-quintic nonlinear restoring force. The system is conser...
A variational approach to dislocation problems for periodic Schrödinger operators
Schr¨odinger operators eigenvalues spectral gaps
2010/12/8
As a simple model for lattice defects like grain boundaries in solid state physics we consider potentials which are obtained from a periodic potential V = V (x, y) on R2 with period lattice Z2 by sett...
First-Order System Least Squares and the Energetic Variational Approach for Two-Phase Flow
First-Order System Least Squares Energetic Variational Approach Two-Phase Flow
2010/12/14
This paper develops a rst-order system least-squares (FOSLS) formulation for equations of two-phase ow. The main goal is to show that this discretization, along with numerical
techniques such as nes...
Variational Approach to Nonlinear Coupled Oscillators Arising in Sirospun Yarn Spinning

2009/2/13
A description of stable working conditions for spinning two-strand yarn is given. A theoretical model underlying Sirospun yarn spinning is also given. Based on the variational formulation established ...
Can a variational approach describe pulse splitting in a dispersion managed system?
nonlinear optics solitons
2011/5/3
When looking for solitons in nonlinear systems, it is often useful to have a simplifying tool. One such tool is the variational method. On the other hand, in the presence of fast oscillations, the wav...
