    Graduate Why does the 1/2E coefficient persist in particle number operator with ladder operators?

    Sorry, I actually want to do the opposite: from the number of particles written through momentum raising and lowering operators to the same number expressed in field operators.

    Graduate Why does the 1/2E coefficient persist in particle number operator with ladder operators?

    How did you find PF?: Google I know how to express Hamiltonian for scalar field written in field operators through the raising and lowering momentum operators, but I can't figure out how to do the same for the number of particles written in field operators: the 1/2E coefficient within the...
