    Ladder Operators for a SHO

    Thanks for the replys...i think my actual problem is between the mathematics and the actual physics. You two guys seems to think very mathematically...where my error came from was my interpretation of the *worded* definititon of the two ladder operators. Thats why I came up with the incorrect...

    Ladder Operators for a SHO

    Hi, Having trouble understanding something here, hoping someone can help...when dealing with a SHO, we can define two ladder operators a and a-dagger. The way I understand it is, applying a-dagger to an eigenstate of H (and that has, for instance, eigenvalue E) will give us a new eigenstate...

    Double slit wavefunction

    Hi, just need a quick confirmation im right with something! :) If we are considering electrons (for example) going through the double slit experiment one at a time would it be correct to define the wavefunction for the electron as follows? \Ket{\Psi} = C_1\Ket{\phi_1} + C_2\Ket{\phi_2}...

    The measurement 'problem'

    thanks, didnt think to look there, i thought they only had papers that were not peer reviewed/published yet. I look at all his papers but stillcant find the one lalbatros mentioned. There is a "why quantum theory" but it doesnt seem to mention measurement at the start :(

    The measurement 'problem'

    thank you all for the replies! lalbatros, im interested in this paper by L hardy, but i cant seem to find the paper. I am right it saying its this man? http://www.qubit.org/people/lucien_hardy/ I've looked on a journal search and cant find that paper, nor is it on that website above...

    The measurement 'problem'

    Hi all, I'm preparing to write a critique on the issue of whether or not there is a measurement problem in QM. Ive been reading various things on the internet but id appreciate if anyone knows any good published papers related to the subject. Also some comments on the issue would be nice...

    Fireplaces and reality

    One thing that you must remember when talking about collapsing wavefunctions is this. You cant just say because im not looking at it the wavefunction wont collapse. Take the fireplace example...you might not be looking right at it but you can see the light reflections from the wall, and also...

    H. G. Wells' The Invisible Man

    if you are just concerned with making someone/something invisible to human sight then you can just take advantage of how our brain processes the images...but this has already been done in the form of camouflage. Obviously camo only works when there is a background for you to hind against, if...

    Barrier Penetration

    to clarify the "silly answer" is not to do with the volts expressed as energy but its to do with the question i have to do...

    Barrier Penetration

    I have a question to do but im a bit confused about one thing. It invloves protons penetrating a barrier. The protons ae quoted to have a KE in the units of eV (which i will have to convert to joules in order to work in SI units). However the barriers height is given in volts. I assumed this...
