What is De-Broglie's interpretation and how does it relate to DBB theory?

[bhobba]

There is one wave in Bohmian mechanics, the statistical one.

That is incorrect.

The wave in BM is very real - its not statistical.

The only difference between De-Broglie and BM is his physical wave is the wave-function divided by a large constant to make his integrals come out nicer - see equations 34 and 35.

Please explain exactly how it is non-local, realistic, and explains Bell for entangled electrons.

Thanks

I assume you mean local, realistic and explains Bell ...

http://en.wikipedia.org/wiki/Bell's_theorem

"No physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics."

de Broglie's double solution theory is not a local hidden variable theory, therefore, Bell's theorem does not apply.

"Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics (though it still leaves the door open for non-local hidden variables)"

In order for there to be conservation of momentum, the downconverted photons are created with opposite angular momentums.

Each of the pair can determine the position and momentum of the other based upon their own position and momentum.

de Broglie's double solution theory is a non-local (hidden from us, not from each other) variable theory.

 

[atyy]

There is one wave in Bohmian mechanics, the statistical one. There are two waves in de Broglie's double solution theory, the statistical one and the physical one.

There are also 2 waves in Bohmian mechanics, the physical one and the statistical one. Like the double solution theory, only the statistical wave is normalized.

In the double solution theory, the physical wave $v$ is also in configuration space, since it is just a constant multiple of $\psi$.

 

[liquidspacetime]

That is incorrect.

The wave in BM is very real - its not statistical.

No according to de Broglie's double solution theory.

"During the summer of 1951, there came to my attention, much to my surprise, a paper by David Bohm which appeared subsequently in The Physical Review [3]. In this paper Bohm went back to my theory of the pilot-wave, considering the W wave as a physical reality* He made a certain number of interesting remarks on the subject, and in particular, he indicated the broad outline of a theory of measurement that seemed to answer the objections Pauli had made to my approach in 1927.3 My first reaction on reading Bohm’s work was to reiterate, in a communication to the Comptes rendus de VAcademic des Sciences [4], the objections, insurmountable in my opinion, that seemed to render impossible any attribution of physical reality to the W wave, and consequently, to render impossible the adoption of the pilot-wave theory."

In the double solution theory, the physical wave $v$ is also in configuration space, since it is just a constant multiple of $\psi$.

Incorrect. The physical wave of de Broglie's double solution theory exists in three-dimensional space.

"An important point is the justification of the guidance formula and of the statistical meaning of the W wave in the case of interacting systems of particles—-a case where the W wave considered in usual Wave Mechanics is supposed to be propagated in configuration space, which is an obviously fictitious space. From the causal point of view adopted by the Double Solution it must be demonstrated that the guidance formula and the statistical interpretation of W both result from interactions between the singular regions of w-type waves evolving in three-dimensional physical space.

Schrodinger’s idea of identifying the W wave of a system in configuration space at first shocked me very greatly, because, configuration space being a pure fiction, this conception deprives the W wave of all physical reality. For me the wave of Wave Mechanics should have evolved in three-dimensional physical space. The numerous and brilliant successes that resulted from adopting Schrodinger's point of view' obliged me to recognize its value; but for a long time I remained convinced that the propagation of the W wave in configuration space was a purely imaginary way of representing wave phenomena which, in point of fact, take place in physical space. We will see in the second part of the present work (Chapter XII) how, from 1927 on, I had sought to develop this approach within the framework of the theory of the Double Solution.

Since 1954, when this passage was written, I have come to support wholeheartedly an hypothesis proposed by Bohm and Vigier. According to this hypothesis, the random perturbations to which the particle would be constantly subjected, and which would have the probability of presence in terms of W, arise from the interaction of the particle with a “subquantic medium” which escapes our observation and is entirely chaotic, and which is everywhere present in what we call “empty space"."

No according to de Broglie's double solution theory.

What you are saying is de-Brogle didnt think it was. Thats his opinon and he is entitled to it.

But insted of quoting De-Brogle - why not explain in own words why you think so?

IMHO, since De-Broglie's wave is a simple multiple of the wave function it's the same thing. That's my view. De-Broglie explains why he thinks its different after he explains its introduction via equations 34 and 35:

'This result may be interpretated by stating that the current statistical theory considers as spread out in the entire wave, devoid of singularity, that which in reality is totally concentrated in the singularity. It is on account of the foregoing interpretation that I simultaneously considered two distinct solutions of the wave propagation equation connected by eq. (33), one, v, having physical reality, and the other, Ã, normed, and of statistical character. I therefore named this reinterpretation of wave mechanics the double solution theory. By distinction of the two waves v and Ã, the mystery of the double character, subjective and objective, of the wave in the usual theory, vanishes, and one no longer has to give a simple probability representation the strange property of creating observable phenomena. Moreover, the distinction between the v and à waves leads to a new outlook on a large number of important problems such as the interpretation of interference phenomena, measurement theory, distant correlations, definition of pure and mixed states, reduction of a probability wave packet, etc.'

That's how De-Broglie interprets it. He is entitled to do that. Me - I interpret it differently - simply as a change of units more convenient for his view of the nature of the wavefunction.

NON-LINEAR WAVE MECHANICS
A CAUSAL INTERPRETATION
by
LOUIS DE BROGLIE

 

[bohm2]

When a downconverted photon pair are created, in order for there to be conservation of momentum, the pair are created with opposite polarizations.

Each of the pair can determine the position and momentum of the other based upon their own position and momentum.

They are not superluminally or physically connected.

They are entangled as they can determine each other's state.

See the 2:00 minute mark in the following.



It is referred to as an exposed variable theory.

I could be mistaken but I don't think it will to get QM predictions. Here is Maudlin's and Grossing's response on the analogy between Couder's stuff and QM:

What the oil-drop experiments provide is a tangible partial analog of the pilot-wave picture, but restricted to single-particle phenomena (that is, this sort of experiment cannot reproduce the sort of phenomena that depend on entanglement). That is because only in the case of a single particle does the wave function have the same mathematical form (a scalar function over space) as do the waves in the oil. Once two particles are involved, the fact that the wave function is defined over the configuration space of the system rather than over physical space becomes crucial, and the (partial) analogy to the oil-drops fails...

Gerhard Groessing agreeing with Maudlin writes:

I agree with Tim Maudlin that it is unclear yet how the Couder experiments can be related to quantum mechanical nonlocality. Having published about 20 papers in recent years on a “subquantum” approach to QM making use of an analogy to Couder’s bouncing droplets, our group recently visited Yves Couder and Emmanuel Fort in Paris, and we agreed that this issue of nonlocality is an open one w.r.t. (in fact, any) fluid mechanics approaches.

Ross Anderson does offer your argument citing the paper you mentioned:

...the droplet experiments do indeed allow you to visualise a pilot wave in the configuration space of two or more particles. In our paper quoted in the above article, Why bouncing droplets are a pretty good model of quantum mechanics, we show that the standing wave created by the droplets bouncing on the vibrating bath is modulated with an analogue of the quantum mechanical wavefunction; where there are two droplets it’s a function of the position and momentum of both of them. In fact you can see \psi with your naked eye in the pictures of the diffraction experiments. Even although this is only a two-dimensional analogue of quantum mechanics, it could be really helpful as a teaching aid, as it can get across the idea of configuration space and the wavefunction in an intuitive and physically realistic way.

But I don't see how Bell's theorem can be avoided. If a local and realistic model was the real deal, it would be a major discovery.

Hi Atty.

He is jumping all over the place.

I am trying to pin it down to specifics which is why I am discussing the paper.

The relevant bit is in equations 34 and 35 in that paper where a very small constant factor is introduced to multiply the normalised wave-function because De-Broglie thinks of the particle as some kind of deformation or something in the wave function. When you do that and calculate some physical quantities it makes sense to introduce it.

However De-Broglie goes further and interprets his small function as 'real' and the usual one not. That's purely his interpretation - and I personally don't agree with it. Since multiplying by a constant simply means a change of units it doesn't change the reality of anything - you are simply working in more convenient units.

Thanks
Bill

If you are correct, then de Broglie had more than one double solution theory.

de Broglie does not think, "of the particle as some kind of deformation or something in the wave function". de Broglie thinks of the particle as some kind of deformation of the physical wave.

de Broglie insists the wave function is fictitious and as such the particle is not some kind of deformation of it.

Well since philosophers can never agree on what physical reality is that's hardly surprising.

And de Broglie's DOUBLE Solution model tells us there are two waves. That's what the DOUBLE in DOUBLE Solution means. You can disagree with that model if you choose to but your insistence there is only one wave in de Broglie's DOUBLE Solution theory is nonsense.

de Broglie continually descibes, in his model, one of the waves as the W wave and the other wave as the u wave.

 

[atyy]

de Broglie insists configuration space is fictitious so the physical wave can not be in "it".

I believe you misunderstand de Broglie http://aflb.ensmp.fr/AFLB-classiques/aflb124p001.pdf. There is potentially a wave in physical space, which is the subquantum medium. However this is not $v$, which is what de Broglie calls a physical wave but is in configuration space. There is also a statistical wave $\psi$ which is also in configuration space. The double solution refers to $v$ and $\psi$ and does not refer to the subquantum medium.

 

[bhobba]

You are not UNDERSTANDING the whole point of de Broglie's DOUBLE Solution theory is that there are two waves. That's the DOUBLE in DOUBLE Solution.

After going through it I understand it only too well.

De-Broglie is making an interpretive assumption I do not agree with.

As for such a wave-function, if the theory is correct, depending on some sub-quantum realm then I would say that's quite likely.

Unless you can evade Bell's theorem, it cannot be done. The only reason Ross Anderson can hold his view that one can have both realism and locality is because he argues that it can be done in fluid mechanics. But I don't think many physicists would agree with this:

In this paper we show that Bell's inequality can be violated in a completely classical system. In fluid mechanics, non-local phenomena arise from local processes. For example, the energy and angular momentum of a vortex are delocalised in the fluid.

They say "local interactions", which does not obviously map to local hidden variables (true light cone). For example, one can have non-relativistic models with only "local interactions", but faster than light propagation (fake light cone from "Lieb-Robinson bound").

I don't know they are right, but they are not obviously crackpots either (at first I thought they were).

 

[liquidspacetime]

That's exactly what he is saying. The physical $v$ wave propagates through the subquantum medium.

"For me the wave of Wave Mechanics should have evolved in three-dimensional physical space."

"From the causal point of view adopted by the Double Solution it must be demonstrated that the guidance formula and the statistical interpretation of W both result from interactions between the singular regions of w-type waves evolving in three-dimensional physical space."

"If the waves of Wave Mechanics were to retain any physical reality, it seemed to me that we had to be able to consider the motion of the particles, as well as the evolution of the wave phenomenon associated with them, in the framework of three-dimensional physical space."

The physical interactions are purely local in de Broglie's double solution theory.

 

[bhobba]

That's fine. No one is saying you have to agree with it. However, when you say de Broglie thinks the particle is a deformation of the wave-function then you don't understand it.

Hmmmm. From page 3 of the paper I started the thread with:

'For me, the particle, precisely located in space at every instant, forms on the v wave a small region of high energy concentration, which may be likened in a first approximation to a moving singularity

Now since the v wave is simply the wave-function multiplied by a constant its obvious the particle is a small region of high energy concentration in the wave function.

Sorry - have to disagree with you.

The difference between BM and De-Brogle is simply that. BM assumes the pilot wave guides an actual particle - De-Broglie assumes its a small region of high energy concentration - OK - I will call it that instead of deformation etc since it seems to bother you.

Thanks
Bill

 

[bhobba]

The physical interactions are purely local in de Broglie's double solution theory.

Since his wave is simply a multiple of the wave-function that's not possible - Bell forbids it.

What is possible is a sub-quantum world that is an approximation to QM to violate Bell.

But the Doublesolution theory, exactly like BM, has been cooked up to be equivalent to QM, so its not possible. There must be interactions that are non-local.

Thanks
Bill
