Wave function of a photon?
Consider a single photon. Since it is not possible to create a photon with a certain frequency it can be characterized by a normalized frequency distribution $f(\nu)$ that is peaked around some mean ...

Why does a laser beam stay coherent when it passes through glass?
If I have a coherent laser beam and I shine it through some glass, the light will slow down because it will interact weakly with the atoms in the glass. However, the beam that comes out the other side ...

Why can't photons cancel each other?
The textbook argument against photons canceling each other draws upon the conservation of energy. Does this mean that energy conservation is a "stronger" principle than superposition? Waves ...

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-...

Experimental suggestions for size and shape of single optical photon (wavepacket)?
Optical photon is an electromagnetic wave produced e.g. during deexcitation of an atom, carrying energy, momentum and angular momentum difference.
So how is this electromagnetic energy distributed in ...

Describing the position of particles in QFT
Background
As someone who has just finished my first year of undergrad, I don't really have any experience with QFT but have some experience with quantum mechanics and the math behind it. I have taken ...

Where is a photon in space relative to the wave?
In electromagnetics you learn that an electromagnetic wave is a perturbation of the electric and magnetic fields that propagate in space according to the wave equation.
This makes sense when you are ...

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 ...
