I know how to solve eigenvalues. My question is not that. I actually don't understand how they get the 4x4 matrix from the previous line of spin product expression? I mean, they directly wrote the Hamiltonian as 4x4 matrix from the previous line. I don't know how they did that from that spin...

Actually, my question is I don't understand the portion indicated in the picture attached. Please see the picture. How they got 4x4 matrix from the previous line, and how they got symmetric and antisymmetric states for those eigenvalues, 1 and -3 respectively and also, how the got the total...

Need explanation of this QM problem Homework Statement I have attached a link to the solution set of some questions from sakurai. But I don't understand clearly the solution of question number 5.29. link: http://www.people.virginia.edu/~rdb2k/homework/phys752/quantum.pdf...

Link corrected here, please click here: http://www.people.virginia.edu/~rdb2k/homework/phys752/quantum.pdf http://www.people.virginia.edu/~rdb2k/homework/phys752/quantum.pdf" I need an explanation very urgently. Please help. Reminding: Question no. 5.29. Questions: how did they found the 4x4...
