In the early part of the twentieth century when it was realized that the massless photon had particle-like properties, de Broglie figured therefor that the massive electron must have wave-like properties-- and the de Broglie
matter wave was born [1, p.55].
One of the interesting dynamical features in the context of Bose-Einstein condensate (BEC) is the formation of
matter wave solitons such as bright solitons [4, 5], dark solitons [5], vortex solitons [6], and gap solitons [7], which have been experimentally achieved before.
He had wide ranging research interests including nonlinear plasma physics, nonlinear geophysical flows, atmospheric physics and environmental sciences, condensed matter physics and
matter wave solitons, high energy density physics, nonlinear phenomena in quantum systems, plasma astrophysics and neutrino plasma physics, plasma-based high energy charged particle acceleration, intense photon-photon and photon-plasma interactions, and fusion physics.
When the cesium atom
matter wave enters the experiment, it encounters a carefully tuned flash of laser light.
The technique of neutron
matter wave interferometry is capable of measuring b for solids, liquids, or gases with a relative uncertainty [less than or equal to][10.sup.-4].
Analogous conclusion holds also for the
matter waves: now the displacement of
matter wave packet at rate [v.sub.g] is related to the maximum probability to find somewhere the set of particles; indeed the first (A9) is also obtained from [delta]([omega]'/k)/[delta]k = 0, which suggests that [omega]'/k corresponds to the rate with which moves the maximum of the packet defined by the dispersion curve [omega]'/k vs k.
What is the mechanism of these
matter wave connections?
Gravity is now explainable as a emergent phenomenon of quantum foam dynamics, but only if we use as well a quantum wave description of matter--gravitational attraction is a quantum
matter wave refraction effect, and also causes EM wave refraction.
It is well known, in quantum mechanics, a
matter wave is determined by electromagnetic wave-particle duality or de Broglie wave of matter [7].
