Duplicate of Do derivatives of operators act on the operator itself or are they "added to the tail" of operators? | |
| Oct 15, 2022 at 8:54 | comment | added | Tobias Fünke | No, $H=i\hbar \partial/\partial t$ makes no sense! $H$ is an operator on the Hilbert space, the time-derivative is not. | |

| Oct 15, 2022 at 8:22 | comment | added | a Fish in Dirac Sea | @TobiasFünke Thanks for your comment sir! So technically, $H=i\hbar\frac{\partial}{\partial t}$ act on Hilbert space but the time derivative dosen't, am I right? | |

| Oct 15, 2022 at 8:06 | comment | added | Tobias Fünke | Note that the time derivative is not an operator on the Hilbert space, tho. So if with $A=\partial /\partial t$ you mean the time derivative, this makes no sense. | |
