Homework Statement What s the inner product <2011|0011> Homework Equations C_{m_1m_2}=<l_1l_2m_1m_2|lml_1l_2> The Attempt at a Solution I'm not sure how to exactly solve this question. The first thing that came to my mind was the Clebsch-Gordan equation, since that's what it looks like...

Homework Statement say the coupled angular momentum eigenstate for two p elections is |2211>. I am asked to operate on the eigenstate with L^2 and L_{z} to verify lm Homework Equations L^2 = L_1^2 +L_2^2 +2L_{1z}L_{2z}+(L_{1+}L_{2-}+L_{1-}L_{2+}) L_{+} |l,m>=|l,m+1> L_{-} |l,m>=|l,m-1>...

so I've went there already, and coundt find them, which is why I'm asking on this forum. maybe i just can't spot them out?

i skipped QM and went into quantum theory so i never went over this. this isn't talked about in my book. all i need to know is the energy eigenfuction for a free particle please? Oh and momentum eigenvalues for a particle in a box?

just a general and quick question because I'm making a formula sheet for my test tomorrow: What is the energy eigenfunction for a free particle and what is the momentum eigenfunction for a particle in a box?

hehe... so it WOULD be an like the identity operator

just wondering... does the parity operator squared give the identity operator?

yeah, the LHC is a discovery machine. it's built to see whether supersymmetry is in fact a valid theory and to look for the Higgs Boson. It's actually a very exciting time for physicists!

ok i did it, and it does show that it would be sin^3 know this, why is it that the higher the power, the larger n is for sin^n?

Homework Statement For a visual of what I am talking about, please visit: http://webhost.etc.tuiasi.ro/cin/Downloads/Fourier/Fourier.html and scroll down to the "Examples of Fourier Transforms" part I am ask to explain why the Fourier transform on the rectangle function was similar to...

What is the different between a vector space and a field? Seems to me that they both are the same thing

then shouldn't this be the same thing as well? 1. It is not the case that I like cars or I like trees 2. It is not the case that I like cars, or I like trees Say X- I like cars and Y=I like trees then using the example from the book i could say ~X V Y, which would read: "I do not like cars or...

that's what I thought, but the examples in the book gives the following: P=Irene has red hair PV~P = "Irene has red hair or she dos not have red hair" if what you say is correct, then the example should say: PV~P = "Irene has red hair, or she dos not have red hair"

Homework Statement This is just a simple logic question that I need a little guidance. Let X= "I like cars" Let Y= "I like trees" Let ~ = not Let V = or How would this be written in symbols: 1. It is not the case that I like cars or I like trees 2. It is not the case that I like...
