I'm missing something obvious because I can't see how to distinguish between Lx and Ly
00:17
<
NomalRaptor >
L and Lz give you Lx^2 + Ly^2, but separating them?

egg: fetch a hydrogen atom from the shelf
00:22
<

One of those bosonic hydrogen atoms.

… breaking the degeneracy is going to involve ladder operators, isn't it?
00:26
<
egg >
also turning on the lights so i can read those lecture notes
00:26
<
egg >
about gross hydrogen
00:28
* NomalRaptor
hands egg 144 hydrogen atoms
00:28
<
egg >
NomalRaptor: tbh i'm shit at QM and it's been 7 years since i took that course so it will take me a bit
00:29
<
egg >
try to poke the actual physicist
00:29
<
egg >
(problem: this requires a flyswatter)
00:29
* NomalRaptor
empties a square box containing 144 hydrogen atoms on bofh
00:41
<
egg >
NomalRaptor: wait, I also have actual QM lecture notes (in german though)
00:42
<
egg >
that's from 2013/2014
00:57
<
egg >
gah how did i forget everything about the hydrogen atom, also why is bofh always unreachable
01:01
<
bofh >
00:16:56 <@NomalRaptor> I'm missing something obvious because I can't see how to distinguish between Lx and Ly
01:01
<
bofh >
I mean those two should have the same eigenfunctions for an s orbital b/c symmetry
01:02
<
bofh >
anyway let me check the link
01:02
<
egg >
bofh: isn't this a p orbital?
01:02
<
bofh >
egg: yeah it is

NomalRaptor: split each state up into tensor products of simple states, I'd say.
01:05
<
egg >
bofh: what do you mean
01:05
<
bofh >
one moment, IRL stuff.
01:06
<
egg >
also shouldn't we summon raising and lowering operators somehow
01:06
<
NomalRaptor >
I mean, Lx^2 + Ly^2 = L+ * L-, but I'm unsure that helps.
01:07
<
egg >
isn't that precisely not the case?
01:12
<
NomalRaptor >
L+ + L- = Lx
01:12
<
egg >
NomalRaptor: L+ L- = (Lx + i Ly) (Lx - i Ly) = Lx^2 + Ly^2 + i Ly Lx - Lx i Ly = Lx^2 + Ly^2 - i (Lx Ly - Ly Lx) = Lx^2 + Ly^2 - i [Lx, Ly] = Lx^2 + Ly^2 - i [Lx, Ly]
01:13
<
egg >
[Lx, Ly] is not 0
01:13
<
egg >
it's i hbar Lz I think
01:13
<
NomalRaptor >
And I can find L+|ψ> because I know n
01:14
<
NomalRaptor >
Yeah, it is iħLz
01:15
<

life doesn't commute
01:15
<

to quote trubowitz
01:17
<
NomalRaptor >
No transit, only cars
01:25
<
NomalRaptor >
At least orthogonality kills crossterms.
01:25
<
egg >
NomalRaptor: yeah, L+ and L- are nicer to work with
01:31

I've only just now realized your name is "nomal raptor" and not "normal raptor"
01:35

01:37

See the gist in the /topic for details
01:37
<
egg >
NomalRaptor: does it work
01:37
<
NomalRaptor >
seems to
01:38
<
egg >
NomalRaptor: I'd say ask bofh to check the results but that would take months >_>
01:38
<
NomalRaptor >
lolsob
01:38
<
egg >
I could try checking the results, but i'm not sure i remember anything about the hydrogenoid atom
01:39
* NomalRaptor
still needs to stab myself^W^Wfigure out C++11 enough to poke at kozai stuff
01:39
<

well, eggsams should take precedence
01:39
<

at some point you can go to ANBO or something and I can feed you some Principia

or dishes that use steam as a structural component, whichever one sounds more like food
01:43

Don't worry about them; I applied an annihilation operator to them last night.
