De Broglie-Bohm theory

שו”תDe Broglie-Bohm theory
asked 7 months ago

Hello,
I don’t know if you are familiar with the de Broglie-Bohm theory in quantum mechanics. It seems to me that it breaks down a lot of irrational interpretations: https://he.m.wikipedia.org/wiki/טעוריית_דברייה-בוהם
Here is an interesting (and technical) book by a Belgian physicist who defends de Broglie’s theory: https://link.springer.com/book/10.1007/978-3-319-25889-8
And here is a series of clear lectures in English about his book: https://youtu.be/1lzp2Med1Nk?si=CtzCIr4EkFQsuxMw

I don’t know, although I am somewhat familiar with Boehm’s views. But this is a place for questions, not for reading references.

Sorry. I just wanted to know how you interpret the quantum formalism.
For example, do you think that a particle has no position before a measurement is made?

מיכי Staff replied 7 months ago

Is that what you wanted to know? So that's what's missing from the book.
In my opinion, before the measurement there is no particle at all, and in any case the question doesn't exist. There is a wave function. A particle in the conventional (classical) sense only exists after the measurement. Bohm probably doesn't agree with that.

In that case, what physical interpretation do you give to the wave function?

מיכי Staff replied 7 months ago

I didn't understand the question.

יוסף replied 7 months ago

A wave function is a mathematical object. What reality does it correspond to?

מיכי Staff replied 7 months ago

The wave function is a mathematical object like the gravitational force or the electromagnetic field. What are they suitable for? You want me to give you a description of the thing as it is (the noumenon)? A bit oxymoronic, isn't it?
