Homework Equations
Hamiltonian is given by eq ? In the attachment
##\phi(x_1,x_2,...x_n,t)= \int dx_1...dx_n \phi(x_1,x_2...x_n,t) a^+(x_1)...a^(x_n) |0> ##
Where ## |0> ## is the vacuum state and ##a(x) |0>=0##
The Attempt at a Solution
[/B]
I can follow the solution and it make sense wanting to move the derivative from delta to the wave function, however, I thought the gradient operator would act on everything to the right, and so you would use a product rule here..so we would get a term where it acts in the delta and the w.f multiplies it as given, as well as and a term where it acts on the wave function and the delta just multiplies it
