| Sep 17, 2020 at 7:23 | comment | added | Roger V. | @Buzz you mean relativistic QFT. In condensed matter QFT operators can be defined differently - depending on how one describes holes. I suppose this is the key to the question: what is meant by "vacuum"? | |
| Sep 16, 2020 at 17:08 | comment | added | Buzz♦ | @Vadim The question’s notation is standard. Field operators in quantum field theory are a mixture of annihilation operators for particles and creation operators for antiparticles. | |
| Sep 16, 2020 at 16:58 | comment | added | Roger V. | If you mean by "vacuum" the vacuum state, then it must be destroyed by an annihilation operator. If $\Psi$ is a creation operator, then $\Psi^\dagger$ is a better notation. | |
