| Sep 17, 2023 at 19:15 | comment | added | user267839 | @Quillo: ok, but the Schrödinger equation which we try to solve there is intrinsically " non classical". So say we solve it using WKB and we let then $h \to 0$. Which pure classical result(s) we would then recover from this? ( if I understand your concern correctly then "semiclassical" means in this approach that performing $h \to 0$ provides something what we know from classical mechanics, but which result is it?) | |
| Sep 17, 2023 at 18:56 | comment | added | Quillo | Taylor around $h=0$ is an expansion around the classical limit, hence the name "semiclassical". | |
| Sep 17, 2023 at 17:22 | comment | added | user267839 | yes sure, but what does it mean here to be "semiclassical"? I' m not sure if calling an approach to be semiclassical is really equivalent to the possibility to expand a system ( more precisely the action S) in Taylor series in $/hbar$... | |
