Miroljub Dugic started the topic A Local Time Scheme in Non-relativistic Quantum Theory in the forum Pragmatist approaches 8 years, 9 months ago
Mainly motivated by relativity, a separate time coordinate for every particle in a composite system has occasionally been introduced. A modification of this idea has recently been proposed as a new foundations for non-relativistic quantum theory—a Local Time Scheme, http://dx.doi.org/10.1098/rspa.2014.0283.
Why should we care about yet another q…[Read more]

Hi Daniel,
thanks for interesting papers.
Regarding the first one, from eq.(4) for the ‘collective’ observables B and B’, it does not seem obvious which kind of measurement of those observables is assumed–on every pair separately [and then calculating the B and B’] or some kind of collective [direct] measurement. Hence my question: whether…[Read more]

Dear Dieter,
Leaving the details aside [e.g. the hydrogen atom is a paradigmatic illustration, while the QBM model is practically the only elaborated sufficiently ‘macroscopic’ model], I am happy to learn that you agree with the non-objective character of the Everett world branching–which is the only objective of this Topic. With the due res…[Read more]

Dear Dieter,
The assumption of “the existence of fundamental ‘observer’ systems” takes us out of the agreed purely technical discussion. Such systems are not implied by the universally valid and complete quantum theory.
Nevertheless, even if it were applied, my argument does not change: Bearing in mind that quantum theory equally applies to…[Read more]

Dear Dieter,
After rereading the reference emphasized in your posts, I can re-emphasize my impression that, at certain point, I do agree with you.
The argument of my previous posts can be re-stated as follows: ‘world branching’ cannot be physically objective [except perhaps in a sense completely strange to me]. In your words: “Nothing ever ‘bran…[Read more]

Dear Dieter [if I may]
Thanks a lot for your comments, which I fully agree and helped me to realize that my first post hadn’t been clear. Let me briefly draw the ‘DIS’ to your attention.
For the sake of the argument, let me illustrate DIS (decomposition into subsystems) via the standard [non-relativistic] treatment of the hydrogen atom (HA).…[Read more]

Dear Dieter and Shan,
Thank you for running this workshop. In full compliance with Dieter’s ‘moderating remarks’, I want here to point out a deeper layer of the Everett [original] interpretation on the purely technical level. The details on what follows below can be found at http://link.springer.com/article/10.1007/s10773-013-1794-x as well as at…[Read more]

Miroljub Dugic replied to the topic Possibilist Transactional Interpretation in the forum Retrocausal theories 8 years, 10 months ago
Hi Michael,
could you please elaborate a bit more on, as you say, “[quantum objects exist outside of spacetime. Is this an accurate reading? If so, it seems] to rule out any realist interpretation of quantum mechanics”? May it be the case that spacetime is emergent for the quantum realm that still allows for a realist interpretation?
Best…[Read more]

Miroljub Dugic posted an update in the group 2015 International Workshop on Quantum Foundations 9 years ago
Dear all,
I would like to draw your attention to a new discourse in quantum foundations that is still on the technical, non-interpretational grounds and much work is yet to be done. Local Time Scheme (LTS) can be found at http://dx.doi.org/10.1098/rspa.2014.0283 and naturally differentiates between the few- and many- particle systems,…[Read more] -
