@DanielSank delving into this paper more thoroughly. thx so much for the ref its what have been looking for lately. nobody is saying QM is wrong except maybe JD. but it does seem subj to possibility of revision. apparently nobody is claiming that right now wrt weak measurements, understood. weak measurements are considered by mainstream physicists as lining up perfectly with QM & so far have heard no dissent/ contrary pov. however consider fig3 of the paper as prime candidate.

it seems like QM cannot predict any variation in locality wrt weak vs strong measurements, but youve now experimentally measured it.

0celo7

@vzn QM is wrong. All hail Archimedes.

Scott Walker is sweating too much.

vzn

@0celo7 such a perfect clown/ jester/ trickster. luv it. only problem is it can become tricky to figure out when youre joking.

@0celo7 Really.

0celo7

@obe of course

It must be hot in the Reagan Library. Most of them appear to be sweating.

DanielSank

@vzn Not sure what you mean by "variation in locality wrt weak measurement".

Be more specific?

vzn

@DanielSank fig 3 is a numerical measurement of a (bell-like) correlation parameter. that correlation is different for local vs nonlocal behavior. why does it change (wrt strong vs weak measurement)? is there a formula for that change anywhere in QM? what is "expected according to theory"?

0celo7

Wow, this is a lot better than the Fox bloodbath.

vzn

1:08 AM

also, another question, hopefully not too naive (am admittedly new in ways to this area). seems like a typical bell experiment uses strong measurements. isnt ~~classic~~ standard QM all about strong measurements? so dont understand why "weaker" measurements lead to "more quantum" behavior and "stronger" ones lead to "more classical".

ACuriousMind

@DanielSank Interesting. Being totally unsophisticated in actual measurements, can the Gaussian form of the probabilities $P(V\vert 0)$ be derived? (Since the path integral formulation hinges on them, afaics)

Bosons are particles with integer spin.

ACuriousMind

@obe Ah, yes. That is the content of the spin-statistic theorem

ACuriousMind

@obe It's a QFT theorem, you're not supposed to (and, in fact, can't) understand it before QFT

0celo7

It's not proved in the majority of texts.

ACuriousMind

I think there are proofs without cluster decomposition/Weinberg's clutter, but, well, I was never worried enough about that theorem to track one down

0celo7

Weinberg does it, but he takes a very nonstandard route through the theory.

@ACuriousMind Probably.

@vzn I was puzzled about that, too. Then I realized the stochastic action is not the action for the quantum system in the sense that it would be the action which appears in the Feynman path integral. The path integral here is a purely stochastic beast, if I understood this right.

@vzn The theory lines are in Fig. 3 along with the data, as stated in the caption.

@vzn First of all, let's discuss your question "Isn't standard QM all about strong measurements?".

I don't know. Sure, whatever. I don't know what "standard" means. If "standard" means "what we learn in school" then yes, it only deals with strong measurements.

But, who cares?

I might only learn first quantization in school but that's an uninteresting (albeit horribly stupid) characteristic of the educational system, not of physics.

@vzn Regarding the other question about how it is that weak measurement shows more quantum behavior and strong measurement shows more classical behavior, I'm not sure why you say that.

The quantum behavior is getting a correlation value >2.

Anything less than 2 doesn't really seem more or less quantum.

Of course, I understand what you're asking: why does the violation only happen for weaker measurement. The best answer is probably "because the control sequence is designed that way". I wish I could give a more in-depth answer, so I'll ask my colleague!

@DanielSank ok thx much :) will ponder it all more...

@DanielSank but how are the theory lines calculated in fig.3? obviously some sinusoidal function involving \phi, but not sure exactly what function. it would be helpful if it were numbered in the text. am not sure of its exact derivation (ideally all the way starting from QM axioms) from the prose.

the graph label refers to <C> and presumably eq.4 but eq.4 has no dependence on \phi.

ah look at that! the graph eqn <C> is not identical to eq.4. eq4 has term E(\beta_1, \alpha_2) and graph has E(\alpha_2, \beta_1). typo? or does symmetry imply that?

The title is a pretty big red flag

yuggib

@Secret there are serious (?) work on multi-dimensional time. At least published on reasonably serious journals

John Duffield

@Slereah you talk about the FABRIC of spacetime because there's this confusion between space and spacetime. It's endemic, and it goes back as far as Wheeler at least. He said "matter tells space how to curve".

Secret

@Slereah But I thought there are some theoretical discussions about multidimensional time (extension to string theoreis to 12 dimensiona spacetime, and then there's something called a thermal like time)?, but the first 5 mins of the video seemed not suggesting those types, and my gut feeling suggest they are misusing biquaterinions

@yuggib Yes I am aware of that, thought the best I can recall from my mem is extension to string theory

yuggib

@Secret There are also applications to QM and QFT

where there is a time for each particle

or something like that

Secret

@Slereah @yuggib I am always fascinating with multidimesnional time, but once I tried to look beyond the popsci introduction, I often have not enough background to work out whcih are the diamonds among the landmines

Should have a look at the paper you just referred me...

Slereah

what do you mean by "multidimensional time"

John Duffield

@Secret : it's nonsense. Time is a dimension derived from motion. See this answer for some general information, and make sure you look at what a clock actually does. Whether it's a grandfather clock or a quartz wristwatch or any other kind of clock, it always features some kind of cyclical motion.

yuggib

I think there are 4 or 5 papers of that guy on it ;-)

they all start with the word "multi-time"

Slereah

If you mean "more than one time dimension", it is not really a good idea

yuggib

12:26 PM

not huge imagination...but at least the subject is clear :-D

Slereah

As far as I know there's no serious theory on the topic

More than 1 time dimension usually results in a pretty fucked up spacetime

Secret

@JohnDuffield if time is emergent from motion, then are we expecting the possibility of other time like concepts to arises from more complex motions?

@Slereah Unlike spatial dimenions, I don't even know how to comprehend the concept, other than a lot of theories often said it allow CTCs and other causal violation things to happen

yuggib

I have no informed opinion on that... ;-)

Just pointed to some paper I once saw, that's the best I can do

Slereah

Well basically it's identical to GR

You just switch the metric

(--++)

It does allow for CTCs up the ass

Secret

https://en.wikipedia.org/wiki/Multiple_time_dimensions

Light cones become something like this, and I am not good at interpreting these kinds of things

It is kinda amzaing that mathematically time and sapce differs only by its signature inthe metric, but this is enough to make it hard to conceptulalise what's going on

John Duffield

12:34 PM

@Secret : no. See the comment here where CuriousOne said "technically time is not a dimension". It's only a dimension in the sense of measure. And a clock doesn't literally measure the flow of time, it "clocks up" some kind of regular cyclical local motion and shows you a cumulative display called the time.

Secret

@JohnDuffield so you mean it is meaningless to consider more than one type of these measures because ultimately they are just ticks measured for an event for each observer in their own frame of reference?

and not reflecting the actual motion?

@slereah @yuggib any paper concerning this topic, whether they mean literally just multiple time dimension as in metric, or particles each has its own spacetime or more exotic is ok, because right now this concept is still kinda fuzzy to me on what direction it is going

Slereah

The only paper I recall vaguely is a paper by notorious crazy man Max Tegmark

Generally on dimensions

space.mit.edu/home/tegmark/dimensions.pdf

It's interesting

John Duffield

@Secret : yes, it's meaningless to consider more than one time dimension. But not because of the reason you gave. Because time is just a measure of local motion. When you move fast through space your measure of local motion doesn't agree with mine, and we talk of time dilation. That's all there is to it. See this answer for more.

Secret

@Slereah He is arguing about why 3+1 spacetime and not other m+n spacetime

Still I need to read again on the ultrahyperbolic part.
It is good that recently I have been studying my numerical lecture notes hence dynamical systems, this might help me to comprehend on the issue of ultrahyperbolicity

Slereah

Ultrahyperbolic equations are just a type of PDE

Ok I have read this in full
Cannot say I fully understand it, but it seems the key idea is that the author think quantum nonlocality can be formulated by considering n relativistic particles each having its own evolution in time and these thus can trace out a bunch of worldines that depends on how we choose the space to be foilated. The resulting wavefunction will then not only be dependent on the position of each particle, but also their individual evolution with time

This paper follows up on thei previous paper by other authors and showed that for a broad class of interactions, the multitime schrondinger equation formalism is inconsistent (that individual schrodinger equations for each particle in the system cannot jointly solve the relativistic n body schrondinger equation)

I am still reading this in detail

They then suggest the usual particle exchanging as a mechanism for interactions in QFT can save this multitime formulation in describing these relativistic systems

I hate and love it when this happens:
I read something about black hole (http://www.nasa.gov/feature/jpl/funky-light-signal-from-colliding-black-holes-explained) and my mind makes up movies about them, or leaves me wondering.

Varying number of time variables... now that's something to wrap my head around of

@Hennes They don't seemed to explain why the light make spirals instead of other periodic patterns

Hennes

Not much explained there. Mostly dumbed down for press.

I wonder how that will deform an event horizon.
If one black hole's pulls you one way and the other hole the other way.
I am guessing that the even horiron would become an oval.

Now if we only could build a craft which could survive in that environment,
drop it just below EH and have it trust outward (so Z does not decrease fast) and then trivially toss another black hole past the first one.

Never mind the force we would need to just toss a second black hole

It probably breaks down after I thought some more about it, but it would make a nice movie.

@0celo7 You shake hands with everyone and you don't use first names. You really are a Southerner.

My image of you is now sitting in a rocking chair on a porch, sipping supersaturated iced tea.
