Firstly, based on the small-signal analysis theory, the nonlinear Schrodinger equation (NLSE) with fiber loss is solved. It is also adapted to the NLSE with the high-order dispersion terms. Furthermore, a general theory on cross-phase modulation (XPM) intensity fluctuation which adapted to all kinds of modulation formats (continuous wave, non-return-to-zero wave, and return-zero pulse wave) . The quantum effect on the Wigner time-delay and distribution for the polarization scattering in a semiclassical dense plasma is explored. The partial wave analysis is applied for a partially ionized dense plasma to derive the phase shift for the polarization interaction. The Wigner time-delay and the Wigner distribution are derived for the electron–atom polarization interaction including.

The Bloch decomposition plays a fundamental role in the study of quantum mechanics and wave propagation in periodic media. Most of the homogenization theory developed for the study of high frequency or semi-classical limit for these problems assumes no crossing of the Bloch bands, resulting in a classical Liouville equation in the limit along each Bloch band.

2 Discrete Dynamics in Nature and Society The DFNLS has inﬁnitely many conservation laws see, e.g., 1–3, two of which are ∂ tρ ∂ xJ 0, ∂ tJ ∂ x J2 ρ 1 2 ∂ x 2. corrections. Note that we avoid the frequently used term “semiclassical limit” for → 0; in particular since in solid state physics the term “semiclassical equation” is reserved for () as a “crystal” version of the Vlasov equation. The limit from a Schrödinger equation with a periodic potential, which yields the “semiclassical.

The first is Whitham’s averaging method, which gives the modulation equations governing the evolution of multi-phase solutions. The second is the Wigner transform, a convenient tool to derive the semiclassical limit equation in the phase space—the Vlasov equation—for the linear Schrödinger equation.

Recently, coupled systems of nonlinear Schrödinger equations have been used extensively to describe a double condensate, i.e. a binary mixture of Bose-Einstein condensates. In a double condensate, an interface and shock waves may occur due to large intraspecies and interspecies scattering lengths.

To know the dynamics of an interface and assure the existence of shock waves in .Another convenient tool to study the semiclassical limit of the Schrödinger equation (and many other problems) is the Wigner distribution [18,27,34,43], which gives, in the semiclassical limit, the Vlasov (or Liouville) equation in the phase space.

Since the Vlasov equation is a linear kinetic equation, it naturally unfolds the caustics and gives.Semiclassical Limit for the Schrödinger-Poisson Equation in a Crystal. By Norbert J.
