I am trying to learn Quantum mechanics and I am familiar with Pauli matricesmatrice but not with group theory. I want to understand SU2 symmetry in common language. I want to knowWhen we talk about Pauli matrix x we simply say that How thisit flips the spin. What SU2 symmetry effects Hamiltoniandoes? I have searched for its explanation and in most cases they describe it in termsWhat is the advantage of Pauli matrices.using SU2 symmetry? Can someone please explain this in simple language?
