An abbreviation for Super-Symmetrical Quantum mechanics.

Consider a QM system with Hamiltonian H and potential V(x) such that H |Ψ> = E |Ψ>

We define a new Hamiltonian H1 in terms of potential V1(x) which is offset by the zero point energy so that:

H1 |0> = 0 ie the enegy of the ground state of H1 is zero.

We define this Hamiltonian in terms of generalized raising and lowering operators A and A dagger such that:

H1 = A_dag A = (p^2/2m) + V1(x)

A = (ip/root(2m)) + W'(x)

Where W(x) is the super potential.

The potential V1(x) can be constructed from the superpotential:

V1(x) = W'(x)^2 - (ћ/root(2m))W"(x)

If we know the H1 ground state Ψ_0(x) then we can derive:

Ψ_0(x) ~ exp(-root(2m)W(x)/ћ)

Which can be used to find the superpotential W(x)

From this superpotential we can derive the partnerpotential V2(x) where:

V2(x) = W'(x)^2 - (ћ/root(2m))W"(x)

which has associated Hamiltonian H2 = A A_dag = (p^2/2m) + V2(x)

This partner potential may allow H2 to have an eigenspectrum which is easier to find. Once this is found we can go from the nth energy level of H2 to the (n+1)th level of H1 by simply applying the A_dag operator. This means we can find the first excited state of H1 by applying A_dag to the ground state of H2.

Note: I wrote this while in class and the prof was talking about some really complex shit I wasn't paying attention to so now I'm fucked for the exam next week.

But sugondese amirite?

At least we still got us a woodshed!

Guy one: Look at that physicist fuck over there doing SUSY.

Guy two: Damn straight brother I hear SUSY sucks a lot.

Guy one: Hell yeah she does!

The woodshed is the coolest place in America. For most of the year, the shed’s function is storing wood or possibly curing tobacco, but for a period of about two weeks it is emptied.

During this time, the shed can be used for throwing parties involving playing pong with 9loko.

A flaw of the woodshed is it’s thin roof which allows sound to easily escape and piss off anyone too lame or stupid to be in the woodshed.

Guy one: Yo what’s yer ass fixin to do this weekend?

Guy two: Prolly do my Ph106 set cause that’s what I do every weekend.

Guy one: Fuck physics - git yer tits to the woodshed cause were mixin up some 9loko.

Guy two: Aight hoss, but this better not be some pussy quarter send.

Guy One: Whatchya wanna drink tonight bro

Guy Two: Yo I'll have me a touchdown

Guy One: What the fuck is that?

Guy Two: Take the superposition of a full send and a sorority formal...

Guy One: What are you some sort of physics fuck?

A Full Send Friday is the pinnacle of all Fridays.

All Full Send Friday's must begin with an inaugural shotgun. All participants who shall be Full Sending must shotgun a beer in 3 seconds or less. Activities include being belligerent, drinking for over 5 hours straight and getting the cops called on you.

Recommended drinks include 9Loko, Kentucky Gentleman and of course some Steel Reserve 40s.

Guy 1: I fucking hate my life bro. My girlfriend left me and I lost my job.

Guy 2: Shit bro, good thing it's Thursday.

Guy 1: Wait does that mean tomorrow's a Full Send Friday?

Guy 2: Well it sure as hell ain't some Quarter Send Friday!
