I liked the inversion of Dirac's statement in your abstract of
an earlier paper (below).<br>

<blockquote class="gmail-abstract gmail-mathjax"> In this
paper is presented a simple alternative model of the dual
nature of
light, based on the deliberate inversion of the original
statement from P. A.
M. Dirac: "Each photon interferes only with itself. <b>Interference
between
different photons never occurs."<br>
</b></blockquote>
While it makes what I feel is a needed refinement of
Chandra/s Non-Interference of Waves position, it perhaps
still misses something that Dirac might not have been aware
of - the existence of identical photons. Your use of
"different" <u>could</u> preclude "identical"; however, the
language is ambiguous and it could also include separate,
but identical, photons. <br>
<br>
I would contend that identical photons (and perhaps the
recently-produced, single-wavelength, photons) could
interact with one another.<br>

About interferometric experiments, perhaps you
could have a look to my paper "Quantum physics

SPIE conference "The Nature of Light" 2015:<br>

style="font-size:14pt">Hello Everybody:
Here is a potentially new “thread” for
debate for our community.</span></p>
<p class="MsoNormal"><span
style="font-size:14pt">“Can a single
indivisible photon interfere?”</span></p>
<p class="MsoNormal"><span
style="font-size:14pt">My answer is a
strong “No”.</span></p>
<p class="MsoNormal"><span
style="font-size:14pt"> </span></p>
<p class="MsoNormal"><span
style="font-size:14pt">I just presented
this paper at the OSA Annual meeting
last week, held at Washington, DC. It
was well accepted by many.</span></p>
<p class="MsoNormal"><span
style="font-size:14pt">It is only an
11-slide presentation. However, it
experimentally demonstrates that, for
Superposition Effect to emerge, we must
have the simultaneous presence of two
physical signals carrying two physically
different phase information incident on
the opposite sides of the beam-combiner
of a two-beam Mach-Zehnder
interferometer. The superposition effect
emerges as purely a classical effect
facilitated by the dielectric boundary
of the beam combiner (classical
light-matter interaction; no QM). The
energies in the two superposed beams can
have any value, no lower limit like
“h-nu”. Thus, single photon interference
is causally and physically an untenable
logic, in my view point.</span></p>
<p class="MsoNormal"><span
style="font-size:14pt"> </span></p>
<p class="MsoNormal"><span
style="font-size:14pt">The experiment
also underscores that the postulate of
the “Wave-particle duality”, is
completely unnecessary for EM waves. In
fact, the Copenhagen Interpretation
becomes more logical and causal without
this postulate. The QM formulation is
essentially correct. We do not need to
degrade it by imposing non-causal
postulates.</span></p>
<p class="MsoNormal"><span
style="font-size:14pt"></span></p>
<p class="MsoNormal"><span
style="font-size:14pt">In the past, I
have also proposed an experiment to
validate that for “particle
interference”, we also need pairs of
out-of-phase particles to nullify the
stimulation of the detector molecule to
generate “dark fringes”.</span></p>
