- Second Quantization in QFT - Physics Forums
For a quantum field theory (which is what was called "2nd quantization" in the early days of modern quantum mechanics though it's just another way to formulate quantum theory of indistinguishable particles in a convenient way, i e , having a formalism which takes into acount the complete symmetry (bosons) or antisymmetry (fermions) of the

- Density matrix elements, momentum basis, second quantization
My intention with using [itex] \varrho [ itex] for the density matrix and [itex] \rho [ itex] for particle density operator, was that, in my mind they are different quantities and so deserve different notations (e g the density matrix evolve according to the Liouville-von Neumann equation while the particle density operator evolve according to the Heisenberg equation of motion)?
- Second Quantization and Field Operators - Physics Forums
Second quantization i's basically pretty simple and straightforward, and has been a staple, an old chestnut, of much of physics throughout the history of modern QM My discussion above could almost be a quote from any of the above references
