NAME: QUIZ 2 PHYS852 Quantum Mechanics II, Spring 2009 A two-spin quantum system has four states. Given in terms of total-spin quantum number s and its z- component m s , these states are the singlet state | 0 , 0 ) , and the three triplet states | 1 , 1 ) , | 1 , 0 ) , and | 1 , 1 ) . Let us assume that the bare Hamiltonian is H 0 = E 0 planckover2pi1 2 S 2 z , where S z is the z-component of the total spin. 1. Give the energy levels of the system and their degeneracies

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
