What exactly is a photon?
Consider the question, "What is a photon?". The answers say, "an elementary particle" and not much else. They don't actually answer the question. Moreover, the question is flagged as a duplicate of, "...

Are photons actually particles at all?
I just read this answer to "What exactly is a Photon?" which has me a bit confused. It seems to be arguing that "photon" is just a catch-all term for any sort of interaction with ...

Why doesn't there exist a wave function for a photon whereas it exists for an electron?
A photon is an excitation or a particle created in the electromagnetic field whereas an electron is an excitation or a particle created in the "electron" field, according to second-quantization.

Does a photon have a wave function or not?
I have read this question:
Why doesn't there exist a wave function for a photon whereas it exists for an electron?
where annav says:
Here is the [wavefunction of the photon,][1] which is a ...

Can we define a wave function of photon like a wave function of an electron? [duplicate]
By definition, the wave function can be obtained by acting the position eigenstate to a state of the system, e.g., $\langle x\vert \psi \rangle$. For the wave function of an electron travelling in one-...

Physical interpretation of photon propagator
Physically, propagator represents the probability amplitude of a particle to travel from one point to another. But the photon propagator $$D_{\mu\nu}(x,y) = \langle 0 | \mathcal{T}[A_\mu(x) A_\nu(y)] ...

What does it mean to measure a photon?
In a lab at the university where I'm studying, there's a detector of gamma rays. We bring a radioactive caesium source near the detector, and the detector clicks now and then. The closer the source is ...

What happen to the electromagnetic waves when a photon's "wave function" collapses?
We interpret the electron's wave function as a probabilistic wave function. During a measurement, it has the probability to collapse to any of the eigenstates of the measurement operator based on the ...

Is photon's direction entangled?
Consider a free electron, with photon, that runs to electron under some angle(as everybody says). Compton scattering is happening, and electron instantly reemits photon in different angle.
First, ...

What is the physics corresponding to the "wave function of a single photon"?
Some of you may have seen my post yesterday which asked essentially the same question as I'm going to ask here and has since been deleted, for which I apologize. I noticed some egregious errors in my ...

Without strict photon position observable (spatial probability density), how is the double slit experiment possible?
I have read this question:
EM wave function & photon wavefunction
Wave function of a photon?
where Arnold Neumaier says:
photons do not have a spatial probability density
He specifically ...

How do electromagnetic wave and photons wave function correspond? [duplicate]
Regarding two-slit experiment against photons makes me conclude, that both frequency and phase of electormagnetic wave and photon wavefunction coincide in space and time.
Am I right?
If I am right and ...
