Like.
I completely accept that. Thanks. -
bhobba reacted to PeroK's post in the thread I Shape of wave function (probability distribution) of a single photon with Like.
Dirac's equation is for the electron. You need QED (Quantum Electrodynamics) for light. Feynman wrote a book on this...

bhobba reacted to Nugatory's post in the thread I Shape of wave function (probability distribution) of a single photon with Like.
It isn't. We explain the double-slit experiment with light by doing a classical calculation of classical electromagnetic waves passing...

bhobba reacted to renormalize's post in the thread I Shape of wave function (probability distribution) of a single photon with Like.
Can you cite a textbook example where the Schrodinger Wave Equation is successfully applied to an electromagnetic wave passing through a...

You could, and then you would indeed get a wave function as an answer. If the process creating the electron allows the electron to be...

bhobba reacted to martinbn's post in the thread A What happens when an operator maps a vector out of the Hilbert space? with
Informative.
The Schwartz space is dense in the ##L^2## space. -
bhobba reacted to PeroK's post in the thread A What happens when an operator maps a vector out of the Hilbert space? with Like.
I think the real issue here is that the original wave function is not physically viable. The space of physically viable wave-functions...

You are missing the point that an operator need not be defined on the hole space, but just on a dense subspace. Look up unbounded operators.

The mathematics on which QM is based demands it.

bhobba reacted to PeroK's post in the thread A What happens when an operator maps a vector out of the Hilbert space? with Like.
That's simply not a valid wave function. Square integrability is not sufficient. An operator on the set of square integrable functions...

bhobba reacted to olivermsun's post in the thread I Phase and group velocity for the wave function with Like.
Maybe start with this question: if you write ##\omega## as a function of ##k##, what does ##\omega(k)## represent? (Think about light in...

bhobba reacted to WWGD's post in the thread A What happens when an operator maps a vector out of the Hilbert space? with Like.
And a good example would be the Laplacian defined in a dense subspace of ##L^2##, as ##L^2## functions may not even be...

bhobba reacted to PeterDonis's post in the thread I Missing proof of the Shell theorem in General Relativity with Like.
This is not a good way to choose a subforum. "Non-standard thinking" in this context means personal speculation, which is off limits...

bhobba reacted to PeroK's post in the thread I Missing proof of the Shell theorem in General Relativity with Like.
For ##r < r_s##, the coordinate ##r## is timelike. Just because you use ##r## as a coordinate doesn't mean it's a radius. The...
