Introductory Remarks,ll always be concerned with electric fields whose spatial variation involves length scales very large compared to the size of the atoms and molecules that are the basic constituents of the material of interest. In this regard, we note that in the visible portion of the spectrum, the wavelength of li

Basic Principles of Nonlinear Wave Interactions: Second Harmonic Generation and Four Wave Mixing,latter. We have seen that we can decompose the electric dipole moment per unit volume into a linear portion, and a nonlinear portion, as in (1.7 a). When we Fourier transform all quantities with respect to time by writing.then introduce the frequency dependent dielectric tensor, (1.3 a,b) become.and

Self-Interaction Effects in One-Dimensional Wave Propagation: Solitons in Optical Fibers and in Pernic structure of the physical system exposed to the electromagnetic field is perturbed far from equilibrium in the course of its evolution. In the soliton pulses encountered in the theory of self-induced transparency, for example, the resonant atoms are moved from their ground state, to the first ex

Optical Interactions in Magnetic Materials,in materials. This is a field with a long history, and also a large number of phenomena are encountered in diverse classes of materials. Thus, we shall be content to explore a few key concepts in the influence of magnetism on the linear propagation characteristics of materials, and non linear intera

Chaos,ies. Our first example was the response of the anharmonic oscillator described by (3.15). This led us to understand, on the basis of this simple model, the qualitative aspects of the frequency variation of the nonlinear susceptibilities, and also the influence of the anharmonic terms on the frequenc

D. L. Mills tests and their application for bank internal purposes, especially in the Basel II periphery. We built up a simulation based framework to take account of dependencies in defaults (asset correlation), which additionally has the potential to appraise the type II error, i.e. the non-detection of a bad
