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></div><div><br></div><div>Best regards,<br><br></div><div>Andrew M<br>_ _ _ <br></div><div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Sep 26, 2017 at 5:05 AM, François henault <span dir="ltr"><<a href="mailto:francois.henault@univ-grenoble-alpes.fr" target="_blank">francois.henault@univ-grenoble-alpes.fr</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

About interferometric experiments, perhaps you could have a look
to my paper "Quantum physics and the beam splitter mystery"
presented in your SPIE conference "The Nature of Light" 2015:<br>

<p class="MsoNormal"><span style="font-size:14pt">Hello
Everybody: Here is a potentially new “thread” for debate for
our community.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:14pt">“Can a
single indivisible photon interfere?”<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:14pt">My answer is
a strong “No”.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:14pt"><u></u> <u></u></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.<u></u><u></u></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.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:14pt"><u></u> <u></u></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.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:14pt"><u></u><u></u></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”.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:14pt"><u></u> <u></u></span></p>
