yeah I think the guy is gonna be permanently in Germany

danielunderwood

12:16 AM

Ahh it's been interesting so far. We have good teleconferencing setups that help, but it would be nice to be able to walk over to his desk and ask a question

enumaris

so the final transformed instruction stream...does it actually run a program or what

danielunderwood

Wait is this the company that you were saying they were gone to Germany and being slow on an offer?

enumaris

yep

same company lol

(It's SAP btw, not a secret)

danielunderwood

That's my understanding. I imagine it moves things around in memory to be able to execute the program with the same instructions. It does say it branches out if something is linked in. But the idea still has my head spinning

You were hired at SAP by a guy in Germany you say?

enumaris

guy came to US to set up the office here and I guess he'll just go back to Germany

yeah but the final program runs like the original program?

danielunderwood

12:18 AM

Did he study string theory once upon a time?

enumaris

like you can still play minesweeper on the "same instruction set" version

don't think so

hmmm...this is odd, this model refuses to even learn a set of 100 data points...

danielunderwood

Yeah my understanding is that the transformed bit runs the original program. I haven't downloaded it to try it out though

enumaris

it could at least memorize it, but not even that

generally I only see this behavior if I'm somehow generating new random numbers at each epoch

even a set of random data points, if it remains constant, will be memorized...

danielunderwood

I think you broke it

Are you still going to be doing NLP?

@enumaris That's just what recruiters (or whoever's pay depends on you accepting the offer) want you to believe. Hiring's such a massive pain nobody with any sense is actually going to rescind the offer for asking more time if they find someone good for the role.

enumaris

@alarge uhh...what's the "that" that you're referring to?

oh I remember now lol

@alarge yeah, you could always just ask for more time certainly.

whoop, so the model is learning random numbers now

and it's actually memorizing it

LOL

within 8 epochs

but it can't learn my data within 50

something really funky is happening

ACuriousMind

12:35 AM

@danielunderwood @enumaris His "universal instruction stream" is basically a very simple virtual machine that can only execute a simple MOVE instruction. Turns out MOVE is Turning complete and he wrote a compiler that translates every program into a table of arguments for these successive moves.

But at the end, the claim that "every program can be reduced to the same instruction stream" doesn't seem that impressive. It's as if someone showed you an interpreter loop and made a big deal about how every program in the interpreted language can be reduced to the instructions in that loop :P

A one instruction set computer (OISC), sometimes called an ultimate reduced instruction set computer (URISC), is an abstract machine that uses only one instruction – obviating the need for a machine language opcode. With a judicious choice for the single instruction and given infinite resources, an OISC is capable of being a universal computer in the same manner as traditional computers that have multiple instructions.

Nielson and Chung’s “Quantum Computation and Quantum Information” is the text I always hear recommended.

Actually you may not have enough of a background. You don’t need to wait the several years to get a complete mastery of Lie Groups, but you should have enough Linear Algebra (more than a lower-division course, probably a first upper-division course) and enough analysis and PDEs to at least follow basic Quantum Mechanics arguments.

Nielson and Chung doesn’t seem to require a whole lot of prerequisites, but that’s partly because they spend a fair amount of devoted to building…

@MartianCactus Going to other stars in a reasonable time frame takes a huge amount of energy. I can't remember the details, or find the Physics comment I posted it in, but last year I calculated that to accelerate 15000 tonnes at 1g until you get to 0.5c consumes as much energy as the economy of the whole Earth currently generates in a year. So even if you could magically transmit the energy from Earth to the ship, rather than having to carry it as fuel, the energy cost is prohibitive.

And why bother going that far? There's plenty of room in the Goldilocks zone of our own solar system. But even that's a dream at the moment, since we don't know how to make a space habitat that's self-sufficient, independent of Earth's biosphere.

I need a condensed matter or solid state guru

by guru I mean a genius. phd level wont cut it

im reading terrible contradicting explanation in ziman and goodstein books

only 1 can be correct

in the free electron model, when one applies an electric field, are all the electrons moving due to the field? or is it just the ones near the fermi surface that are affected?

each book has a different take. so, what is the truth?

knzhou

@tttt Well, we know that Newton's second law holds, F = \hbar dk/dt, where k is the crystal momentum.

Say, before applying the electric field, you have electrons with crystal momenta -10, -9, -8, ..., 8, 9, 10.

Afterward you have -9, -8, ..., 8, 9, 10, 11.

You can choose to describe this in words as "only the electrons on the ends changed" or "all of them shifted over". But the actual effect is the same. They're just different ways of describing the same thing.

t t t t

yes the net effect is extactly the same, but ziman claims that physically only those near the fermi surface are actually affected

knzhou

In fact, it's meaningless to ask "which electrons really moved" because electrons are identical.

t t t t

I think this matters when a temperature gradient is applied rather than electrical current

knzhou

You have some occupancy of states before, and a different occupancy of states after. How you interpret that is up to you.

All of the electrons obey F = \hbar dk/dt.

t t t t

2:07 PM

true. but it is not meaningless to ask the momentum of the quasielectrons that responded to the e field

knzhou

Sure, in that case, they all respond.

t t t t

when a temperature gradient is applied, the fermi sphere has a thermal broadening (or sharpening in case of colder), in that case only those near the surface really respond

hmm i would tend to think that only those near the surface actually respond

for when the E field is turned on

that's ziman's take. i haven't checked his explanation

he has written notes called "a guide to the fermi surface" or something like that

knzhou

If only the ones in the surface changed their crystal momenta, they would run right into the ones inside the Fermi surface, which in this picture would not be changing their crystal momenta at all.

It sounds like you're proposing -10, -9, ..., 9, 10 --> -9, -9, ..., 9, 11, which can't work.

t t t t

-10, -9, ..., 9, 10 --> -9, -8, ..., 10, 11

knzhou

Right.

So now consider just a crystal lattice with a single electron.

Do you agree that the unitary corresponding to turning on an E field for a while is like |-10> to |-9>, |-9> to |-8>, and so on?

t t t t

2:13 PM

there is a very nice picture in Band theory and electronic structures by John Singleton

not really. from -10 to 11 directly

knzhou

So for a single electron, an electric field will do absolutely nothing to it, unless it happens to have the magic momentum -10, in which case it will give it a huge impulse?

Why even -10? Why not -20?

t t t t

because -10 is -p_f

the fermi momentum in a direction

knzhou

I'm talking about just a single electron right now. There is no Fermi anything.

t t t t

(direction of the applied E field)

oh wait then im totally lost

there's no electronic gas

knzhou

I just want to make sure we agree on how a single electron behaves.

Does what I said earlier sound reasonable?

t t t t

2:17 PM

i think so yes

knzhou

Now in the free electron model, you assume there are a whole bunch of electrons around, but by definition their dynamics don't affect each other.

So if, for one electron, a unitary maps |n> to |U(n)>, then for two electrons the state |nm> is mapped to |U(n)U(m)>.

t t t t

well they have to satisfy pauli's exlusion principle. cannot share the same state

the -10 cannot go into -9

knzhou

Actually, that has no effect here.

t t t t

hmm why not?

knzhou

If the state starts by satisfying the Pauli exclusion principle, then it'll stay that way upon unitary evolution.

Say we had 1 and 2. Evolution takes that to 2 and 3, no problem. If evolution took both 1 and 2 to 4, then it wouldn't be unitary.

t t t t

2:19 PM

alright, if they all move at once

knzhou

Yes, it's a continuous process.

You gradually move from "|-10, -9, ..., 9, 10>" to "|-9, ..., 9, 10, 11>". At intermediate times, you have a quantum superposition of the two.

But at all times, all the elements of the superposition satisfy the exclusion principle.

All the behavior is perfectly smooth, there are no magic jumps.

t t t t

but then why does a grad T only affects those near the fermi surface

knzhou

Changing the temperature is totally different from unitary evolution. You don't have a pure state to begin with.

Changing the temperature changes the thermal distribution, and it just happens that this distribution only varies significantly near the Fermi surface, that's all.

t t t t

why when there are pockets in the fermi surface or condensation of electrons at that surface, the number of carrier density drops

knzhou

No idea!

Actually, I've never really studied solid state. I'm just going off what I know from studying quantum mechanics in general.

One thing to watch out for is that a lot of solid state explanations seem to be using classical intuition even when the whole situation is quantum.

Probably because of the history of the subject.

It helps you get the right answer, but it also can be confusing because the classical intuition suggests things that are absolutely not true in the quantum formalism. Like the idea that everything under the Fermi sea is "locked in place".

That's not true in QM but it can be used to upgrade a classical model into something that kind of matches what real QM says.

Good luck figuring all this out!

t t t t

2:30 PM

thanks man im reading ziman. what i get is that the conductivity is related to the topology of the fermi surface

hmm he clearly states that deep inside the fermi sphere the electrons are prevent to react to the applied E field due to pauli's exclusion principle :(

and that even though it looks the same as if all the sphere had moved, this is only a misleading concept

pages 216-217 of "Principles of the theory of solids"

it kinda makes sense intuitively to me. if the fermi surface represents the set of electrons having the same energy, where no other electrons have higher energy

then a small perturbation such as an E field, B field or grad T, could potentially only have an effect on those electrons having that energy

so even though the electrons goes from -10 to 11, it's actually almost the same energy

small perturbation

knzhou

3:04 PM

^ I guess that depends on whether you're thinking of this as a time-dependent or time-independent problem. Everything I said was with a time-dependent picture, but I see what you mean for the time-independent case!

t t t t

grosso's book : in reality, the generally valid Eq. (11.34) shows that in any case (parabolic or non-
parabolic bands) only the electrons at (or near) the Fermi surface can change their

state under perturbations and are relevant in the transport phenomena.
11.4.2

so i guess it clears things up definitively. only the electrons near the fermi surface are indeed affected by the E field.

when the surface is spherical, it's as if the whole sphere was displaced. but when it's not spherical anymore, it doesn't hold anymore.

p 504 (book has over 800 pages!!!)

they arrive at an expression for the conductivity in term of an integral over the fermi surface only. it reduces to Drude's formula in case the surface is spherical only

vzn
