I'm in one spatial dimension. I want to know what the operator is that will turn [itex]\psi(x)[/itex] into [itex]\psi(x + \frac{vt}{2})[/itex], where [itex]t[/itex] is, yes, time. I know that, usually, we say that (assuming [itex]\hbar = 1[/itex]) [itex]e^{ipa}[/itex] is the generator of translations by [itex]a[/itex], but I was wondering if things were different once we put in a [itex]t[/itex].(adsbygoogle = window.adsbygoogle || []).push({});
