The Attempt at a Solution
I have completed this question and the needed commutator relation is that ##[a(x),a^+(x')]=\delta(x-x')##
However I have it all with the integral i.e.
##\int dx_1 dx_2 a^+(x_1)a^+(x_2) \Psi (x_1,x_2) | 0> ##
and
##\int dx_1 dx_2 a^+(x_1)a^+(x_2) \frac{-h^2}{2m}(\frac{\partial^2}{\partial x_1^2}+\frac{\partial^2}{\partial x_2^2} ) \Psi (x_1,x_2) |0> ## such terms etc
and am unsure of the final argument needed to explain why it holds without the integral.
Many thanks for your help.
