Many-body Quantum Mechanics
... the method of using annihilation and creation operators acting on a Fock space as ”second quantization”. As should be clear from the above, this terminology is misleading in the sense that ψ̂ is not a once more quantized version of the wave function, but an object which is directly (or via a Fourier ...
