I Showing that operators follow SU(2) algebra

Click For Summary
To verify that the raising and lowering operators for two quantum oscillators follow the SU(2) algebra, one should express the operators T_1 and T_2 in terms of T_- and T_+. The SU(2) commutation relation is defined as [T_1, T_2] = i ε^ijk T_3. The discussion emphasizes the importance of distinguishing between the SU(2) group and its corresponding algebra, denoted as \mathfrak{su}(2). The provided basis transformations link the operators to the Pauli matrices, which can aid in the verification process. Understanding these relationships is crucial for confirming the algebraic structure.

For two quantum oscillators, I have raising and lowering operators

and

, and the number operator

. I need to check if operators below follow

commutation relations.

Now as far as I know, SU(2) algebra commutation relation is [T_1, T_2] = i ε^ijk T_3. So, should I just get T_1 and T_2 in terms of T_- and T_+ and then try to check if I get they follow the SU(2) commutation relation?

Just a pedantic comment but ##SU(2)## is a group, and ##\mathfrak{su}(2)## is an algebra.
