3	The cleverest way to calculate $\left[\hat{a}^{M},\hat{a}^{\dagger N}\right]$ with $\left[\hat{a},\hat{a}^{\dagger}\right]=1$
3	Question on Section 9.1.3 in “Conformal Field Theory” by Philippe Di Francesco et. al
2	Variational approach to search the excitations. What will happen if start from wrong reference state?
1	Does quantum manybody theory with 2nd quantization completely equivalent to 1st quantization formulation?
1	Are there any good reading materials for variational approach in many-body theory? [closed]
