Text Box:  In the second experiment here, we demonstrate the absolute existence of the vacuum field energy and the breathing of atoms.

Every single frequency of the electromagnetic spectrum is found in the vacuum field. 
The atom, through its breathing at every energy level, generates a series of wavefronts through the vacuum field. 
The atom impelled into high motion, can thus produce an intense series of detectable (bow-shock) wavefronts to precede it –  at speed c –  through the vacuum field. The wavefronts can thus go through both slits even if the atom itself gets stopped, say, between the (open) slits. And this is exactly what requires verification in this (unprecedented!) experiment; which is, briefly:

Prediction 2
The Breathing of Classical Matter
   In the two-slit experiment, let us consider now a stream of matter particles, instead of photons.
The figure below shows perhaps the easiest matter particles to generate – a stream of electrons.
[NB: Ideally, it should be 'neutral' particles such as atoms or molecules. That is, it's best to avoid 'charged' particles like electrons or protons here to circumvent argument that the screen effect can be caused by the magnetic waves such ionized particles propagate – even though magnetic waves are basically the very same respiratory waves but caused by (highly directional) dipoles;
see The Pulsar, link below.]

There is now the classic argument about a particle of matter (or of light) going through only one slit or the other slit and not through both at the same time if indeed it is a particle and not a wave. From what we now know, this argument is of no relevance anymore in quantum physics. Each speed-c wavecrest generated by even a single matter (or even energy) particle goes through both slits irrespective of the particle trajectory, whether it be through one slit or the other. For that matter – and this is the crux of the prediction here – the particle need not even go through either slit at all. In other words, the experiment may be so deliberately arranged to ensure that the particles are targeted only to hit a point right between the slits, thereby denying the particles passage through the slits altogether. And the interference fringes on the screen downstream will still be a reality. 
(Contact between two material  bodies, for instance, is thus made only ‘by proxy', that is, through their bow waves, and never at the body-to-body nuclear level, other than in nuclear reactions; see Nuclear Reactions for details.) 
 Basically, therefore, each of these energy quanta pulsed by the matter particle will be no different to the photon. 
Thus, even from a single atom, the quanta that precede the atom's motion will be a series of pulsed photons (capable of entering both slits at the same time).
Text Box:  Trial and error only could yield optimum conditions for a given apparatus. Experimenters, of course, would prefer to use their own ingenuity for the experimental setup. However, extra care should be taken to ensure: 

Symmetry of flux through slits
Frequency doubling, the basic cause for the fringes, is made possible only by ensuring symmetry of the energy flux entering the two slits (in effect, to mimic a pair of like hammers alternately striking an anvil with equal force; see also last figure in Part 1.)
Any objects, such as probes, along the particle trajectory will scatter and drain off energy from the wavecrests. Energy coherence and symmetry of flux through the slits can thus suffer; and any such lopsidedness will only blank out the screen effect.
   Finally, in place of the stream of particles in the above setup, single-file (matter or energy) particles, too, can provide the same 'fringe benefits' to the experimenter. In this case, the particles are shot one at a time in rapid succession; there will be no need of draining particles from between the slits, since a particle (bulk) will, of course, not go through both slits at the same time.
Note of caution: Although this is true in principle, the intensity of waves emanating here, in practical reality, will generally be too low to produce any unambiguous positive result.
Text Box: The atom laser, a bright, coherent matter wave derived from a Bose–Einstein condensate, holds great promise for precision measurement and for fundamental tests of quantum mechanics. …Here, we report an experiment that uses two spatially separated Bose–Einstein condensates of rubidium in different internal hyperfine states, and show that while continuously output-coupling an atom laser beam from one Bose–Einstein condensate, we can simultaneously and irreversibly pump new atoms from a physically separate cloud into the trapped condensate that forms the lasing mode.
