Hi all, Given that the question: From what i know , I am not sure how this equation can help me estimate the von-klitzing constant? Or is there another way? Thanks!

@hutchphd ah I see, so I do still use V(x) = mw0x^2/2 for equation 6.52? Anyways thanks for helping, really appreciate!

And do I have to introduce an expression for wave function u(x) to solve for the energy of confining parabolic potential?

@hutchphd @stevendaryl So is V(x) = mw0x^2/2 or the one that is circled in blue below equation 6.52? Because I went to spend a few hours using V(x) = mw0x^2/2 into equation 6.52 but to no avail I can't link it to the definitions .

Hi all, thanks for replying! @stevendaryl The book doesn't really give a hamiltonian for the particles in the wire but its gives a SHO equation in landau gauge which gains confining potential which I am not sure can it be used in pkace of that? @hutchphd I have never done anything related to...

Hi all, How to derive the energy of a parabolic confining potential in a wire as shown below? I tried to follow the derivation of the harmonic, oscillator like we did for the quantum well and the magnetic field but i can't find anything that has an expression that come close to the one shown...

Hi thanks for replying... this is my first time using this forum to ask questions relating to physics so I wasn't sure where to exactly post it anyways, I'm not sure what spin state component the question ask me to use like is it x,y or z?And also what is the meaning of alpha and beta? Like what...

Hi all, There is this question; Firstly, I am new to quantum mechanics and there are a lot of terms I am unfamiliar with. So there is this question that asks me to develop a method to reconstruct state and I have no clue how I should start with. Any help or steps to solve this type of...
