but there are localized photons but we can have localized modes, no? After all sometimes we talk about photons coming and doing something (like in the photoelectric effect for example... )

in classic electromagnetism, two plane waves with the same frequency and -1 phase difference can cancel each other. due to conservation of energy, I assume that photons (that so far we have treated as sort of EM energy chunk traveling through space) can't truly cancel each other. then, what...

a photon have defined frequency , but we treat it as a localized particle ,how that can be? if i am looking at second quantisation, photons are modes of the electromagnetic field , and they are not localized at all , but we do know that photons are somewhat localized , like in the...

thank you!

it doesn't answer the question :( the video does not explains what guides the interaction between this plasma cloud and Earth's magnetic field

So, what is the mechanism that causes this deflection?

I was thinking to myself, how come are particles coming from the sun gets deflected the way they do due to Earth's magnetic field? They are getting pulled toward the poles, but if we think in terms of classical Lorentz force, they should not just follow the magnetic field lines, but rather start...

I have one-dimensional problem with a one-dimensional potential I want to know the energy domains that will result in discrete energy levels and the energy domains that will result in continuous energy levels In my lecture, my professor gave the example of v(r) = 1/r (r>0) (hydrogen atom...

unfortunately I am currently learning statistical mechanics without a proper background in qm (which i will get in the next semester),so we had to take the concept of identical particles as given. i still can't understand why on the one hand you said that the two configurations are the same but...

correct , i am unsure why the idea of identicle partices does not states that we basically need to count all the possible configurations where there are k particles in one side as one configuration (for example ,why the configurations left- A,B right - C and left -A C , right-B can be treated...

if what i said is true. the probability of having k particles on the left side of the box is simply 1/(N+1) (independent of k).

assume i have a gass made from N identical particles in a box and i want to calculate the probability for k out of N particles to be in the left side of the box. the problem is ,that if we treat the N particles as identical , each state in which exacly k of the N particles are in the left side...

I'm not talking about ideal gas but on general systems. you can take another combination as well, such as PN, and the question stays the same.

assume I have 3 systems a,b and c. the equilibrium between a and c can be described by the equality PcVc = f(A1,..., An) and the same for b and c - PcVc = g(B1,...,Bk). why does the equality g(B1,..., Bk) = f(A1,..., An) describes an equilibrium between A and B? the 0th law states that if A and...

If I'm trying to solve the problem of a particle in free space (H = P2/2m ). the eigenfunctions of the Hamiltonian cannot be normalized. now assume I have a legitimate wave function expressed in terms of the eigenfunction of H and I want to measure its energy. what will happen to the...
