    Abstract:

    Two samples of nominally pure Bi(12)SiO(20) show distinct behavior in experiments of diffraction efficiency kinetics, and two-beam coupling. The results can be understood by the presence of fast and slow gratings due to electrons and holes.

    The de Broglie Wavelength

    In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...
