gentzen replied to the thread Graduate Quantum properties and Van Hove singularty.I am not really active at https://www.physicsforums.com/forums/atomic-and-condensed-matter.64/ From time to time I think that I should...
-
gentzen replied to the thread Undergrad Help me understand indeterminism in standard quantum mechanics.I think we should be more critical towards people like Niels Bohr (and also John Bell) who insist on never saying or writing anything...

gentzen reacted to iste's post in the thread Graduate Understanding Barandes' microscopic theory of causality with
Like.
No, all physically meaningful probabilities. If you have a probability describing a physical system that is not approximated... -

Like.
All descriptive probabilities yes. Descriptive probabilities become normative only when combined with the stationarity assumption, that... -
gentzen reacted to Demystifier's post in the thread Undergrad The equivalent concept of phase change in classical mechanics with
Like.
The phase of the wave function is analogous to the Hamilton-Jacobi function ##S(x,t)## in classical mechanics. If ##S(x,t)## is a... -
gentzen reacted to iste's post in the thread Graduate Understanding Barandes' microscopic theory of causality with
Like.
Yes, that's the paper. Sure, I think the stcohastic-quantum correspondence is a valid way to argue that the quantum state is not... -
gentzen replied to the thread Graduate Understanding Barandes' microscopic theory of causality.Even this part is not so clear: I probably asked one specific instance of those "continuity properties" even more explicitly...

gentzen replied to the thread Graduate Understanding Barandes' microscopic theory of causality.You mean https://arxiv.org/abs/2602.07402 (The ABL Rule and the Perils of Post-Selection)? Your formulation sounds like you talked about...

This is just my thoughts on the new Barandes papers. Regarding Barandes' Pilot-Wave-As-Hidden-Markov-Models paper, I feel like... -
gentzen reacted to pines-demon's post in the thread Graduate Understanding Barandes' microscopic theory of causality with
Like.
My issue here is the lack of a simple example, outside of quantum mechanics. Just because you can go from one picture to another it... -
gentzen replied to the thread Graduate Quantum measurement problem (ie double slit experiment) question.I guess you meant (copy&paste mistake): https://arxiv.org/abs/1712.06605

gentzen reacted to A. Neumaier's post in the thread Undergrad The Born rule -- 100 years ago and today with
Like.
I have written a new paper: A. Neumaier, The Born rule -- 100 years ago and today, Manuscript (2025). arXiv:2502.08545 Abstract... -
gentzen replied to the thread Graduate Exact symmetry, quantum states, and symmetric dynamics.As long as you are requiring exact symmetry, my answer to QuarkyMeson above provides one answer: If everything is exactly symmetric down...
-
gentzen replied to the thread Graduate Exact symmetry, quantum states, and symmetric dynamics.So the small part broke the symmetry, no? And not just for itself, but globally! Or maybe not, if we assume that another...

gentzen reacted to Demystifier's post in the thread Undergrad Necessary conditions for the uncertainty principle with
Like.
Which, by writing ##q=x##, ##p=y##, becomes the usual quantum mechanical continuity equation. So pre-quantization, at this level, is...
