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].
At such an ultra-low temperature, all atoms gather in the lowest possible energy state, lose their individual identities, and act as a "giant matter wave."
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].
The feasibility of this goal has been demonstrated experimentally by the Host Group, the Experienced Researcher and others, driven and supported by theoretical work.The NANO-Q project aims to create a source of free cavity cooled nanoparticles suitable for mesoscopic matter wave interferometry.
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.
The recent achievements of laser cooling and manipulation of atoms as well as latest developments in atom optics have moved the whole field to the boundary of the new regime where coherent matter wave interactions will become dominant.
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].
