Dario, much thanks for pointing out the paragraphs where I forgot to include h-bar. By the way, the reason I write "2 pi h-bar" instead of "h" is cause I just can't stand having more than one physical constant running around that does the same thing. Thanks again, I've already made the appropriate changes. Fortunately, I checked units later in the paper while writing it, so the h-bar pops back up where it's needed.
It sounds like a good idea! It could also be good to restore c in the relativistic results when discussing interpretation or classical limits.
In particular I really think that using s to indicate proper time is a little disturbing for units. What about following Schutz and use tau instead so that ds=c*d(tau)
Complex numbers are so deeply inscribed in our brains in school that by the time we get out of grad school it's hard to remember that they really are just another group, as opposed to the sort of numbers that are used to figure out what we should pay for a beer. Group theory in QM is cool stuff, but I found it difficult to learn, and I was a math major. As a beginning grad student, the book I read on my own as an introduction was "Lie Algebras in Particle Physics" by Georgi, and I could not get past the first 3 or 4 chapters before I had to run to a faculty member for assistance. Since that time I went back to school and studied more math and it's more natural now. But like I say in that paper, I don't think symmetries do us much good when it comes to uncovering how the world is built (as opposed to how stuff in the world interacts, where group theory is irreplaceable). Other than that, the secret I've used for learning difficult things is to work as many practical problems as possible.
Thanks for the reference: I hate to say it but I should have taken that high energy physics course at least for that reason: half of that course was based on the Georgi. High energy physicist were/are monopolizing the resources of my home university and I could not stand them. All they wanted were docile blue-collar scientist to send to CERN in Geneve for low-profile jobs. Too much power in the hands of ignorant people can be really bad for scientific education...
I have in my hands the Hamermesh (Group theory and its applications to physical problems, Dover): do you know anything about it? Is it worth it?
Re: "As of your second answer..."
While I'm horrible at misusing terms, a failing which gets worse as I get older, I think that dissipative is the word I want. If you start with a pile of probability in one spot, that term will dissipate it, that is, it will spread it around and flatten the pile. This kind of dissipation is not the same as the frictional dissipation that reduces total kinetic energy. But the equations are the same. That is, if the probability density had instead been a wave, the above term would be a dissipative term (i.e. one that causes the wave to dissipate).
Well I strongly feel a geometrical point of view would be very useful... I believe that the term has a strong connection with another (unsolved to my knowledge) problem: the geometric interpretation of capacitance of a conductor. Terms of the form lapl(V)/V appears when you search for such a thing...
Another strong feeling that I have developed in this area is that there a very strong connection between e.m. energy density and probability density that should be explored.
I have been working along a line re-opened by Gough with his 'recent' work on Hertz potentials and this has given me some insight that justifies this perception.
Re: "...the phase of the wave function oscillate without any limit."
This is true. But in my case I'm trying to make classical sense out of the Schroedinger's wave equation with the realistic h-bar value. I see it as an unavoidable part of the universe. I'd just as soon take a limit as h-bar goes to zero as I would take a limit as c goes to infinity or zero. Maybe there's a utility in it, but I don't see it. The usual reason for doing it is to show that quantum mechanics will result in the classical world we live in, a proof that I find rather weak.
Well going to the limit with constants is always a little problem. You have probably noticed how going c->oo in the Lorentz transfo's does not return Galilean transformations if a system is 'large' enough... and hence classical mechanics is not only for small speed but also for 'small' systems.
Still I believe it is interesting to
understand how S which is just a chracteristic function of hamiltonian mechanics ends up to regulate the phase of the wave function through hbar... I should have a fresh look at Goldstein's explanation of S as a phase of the classical wave associated with a particle motion...
Re: "...What about a rotational velocity field?"
Well, if we consider Schroedinger's equation as two reals, with one being the probability density and the other being the velocity potential, then we're already screwed because there are numerous simple examples of solutions to Schroedinger's equation for which a (single real valued) potential does not exist. See equation (5.8) in my paper for a concrete example, which is, as is typical for angular momentum eigenstates, a rotational velocity field. If, on the other hand, you are willing to have the velocity potential be multiply valued, then you end up with "unphysical" solutions that are not multiples of h-bar. It is only when you push everything back into a complex number version that the velocity potential makes (single valued real) sense.
I do not know this results but I guess studying the mechanism by which complex field make sense of real "unphysical" results can be worthwhile. If you have a reference I will appreciate...
Re: "Well here I do not really see what you claim: ..."
Good question, I'll explain more fully in the article. In quantum mechanics, a plane wave is represented by a wave of the form exp(ikx-wt). This wave corresponds to an even distribution of particles. That is, |Psi| is everywhere constant. The wave corresponds to a steady velocity of particles. That is, the momentum P is everywhere constant. In other words, the described physical situation is one that has no sine or cosine dependence.
Another way of putting this is to note that if you cover up one of the slits in the 2-slit experiment, the resulting pattern has no sine or cosine dependency. And yet when two are present, there is interference. In other words, while there is a sine/cosine dependency in the complex description of the two waves, that dependency has no physical significance, except in the interaction of the wave with itself (or with another like wave).
Well I will re-read that part of the article and also read further ahead, since I had probably misunderstood what items you were comparing...
I've got to get back to my daily grind, but I'm working hard on using Kaluza-Klein to get E&M running on this new topology. Do you mind if I thank you in the paper for pointing out the error? I hate to intrude, especially as this is considered crack-pot theorizing by the mainstream. I really can't express how indebted I am to you for pointing out these errors and confusions.
Carl
Well I am really happy to see a seriuos theory in this rather messy section and I am even more happy to see someone on the same line of my conjectures... Feel free to thank you me ;) I am trying to keep my physics alive now that I have decided to stay out of the academia for some time. Feel free to ask for any further help or opinion...
