Diffraction of Light by Supersonic Waves in Solids

Solitary waves and supersonic reaction front in metastable solids.

Motivated by an increasing number of remarkable experimental observations on the role of pressure and shear stress in solid reactions, explosions, and detonations, we present a simple one-dimensional model that embodies nonlinear elasticity and dispersion as well as chemical or phase transformation. This generalization of the Toda lattice provides an effective model for the description of the o...

Coherent Control of Atomic Beam Diffraction by Standing Light Waves

Quantum interference is shown to deliver a means of regulating the diffraction pattern of a thermal atomic beam interacting with two standing wave electric fields. Parameters have been identified to enhance the diffraction probability of one momentum component over the others, with specific application to Rb atoms. PACS number(s): 32.80 Qk, 34.50 Dy, 39.20 +q, 39.25 +k, 03.75 Dg Typeset using R...

Diffraction and Interference of Plane Light Waves

In this experiment you will become familiar with diffraction patterns created when a beam of light scatters from objects placed in its path. Such experiments were important historically as they were crucial in establishing the wave nature of light in face of competing theories that described light in terms of geometrical rays of discrete objects. Only a wave theory can give a quantitative expla...
