Homework Statement Show: <Jx>=<Jy>=0 Homework Equations Jx=1/2(J++J-) Jy=1/2(J+-J-) The Attempt at a Solution <jm l Jx l jm> = < jm l 1/2 J+ l jm> + < jm l j- l jm > = < jm l h/2 sqrt [(j-m)(j+m+1)] + h/2sqrt[(j+m)(j+m+1) l jm > i am not sure how to apply the next step

the problem was stated as above. find energy levels and radial wave function for the s states (l=0). i know how to solve each component individually (with V=-V0 or V= infinite). its the combination of the two that confuses me. I mentioned the above attempt because I've seen another solution...

Homework Statement particle in a spherical well potential where V(r)= -V0 for 0<r<a and infinite for r>a Homework Equations The Attempt at a Solution can i simply solve the problem for V0 treating the region r>a as zero and then solve 0<r<a treating V0=0 with the infinite...

thank you for your responses. allow me to clarify what i am asking. i will do the research in teleportation regardless if i get the PhD or not. this research is all i care about, otherwise, physics does not interest me, only this purpose. i will fund my own research, i will not work for someone...

i will finish my undergraduate physics in two semesters. i am considering getting my PhD with research on entanglement or quantum teleportation. i want to research teleportation to make it possible. i am wondering will the PhD be worth getting given the nature of my research. i already have a...
