How does the Pusey-Barret-Rudolph (PBR) theorem not just disprove hidden variables?

In Quantum Mechanics, two different wavefunctions can have a non-zero probability of finding a particle at a position $x$. According to hidden variable theories, if a particle is found at $x$, it was ...

What does happen if we use a delta function for density on the De Broglie–Bohm theory?

I was reading Pilot wave theory and De Broglie–Bohm theory pages on Wikipedia that I found how similar they are comparing to classical physics and I wondered what happens if we just replace the ...

Regarding Pilot Wave Theory [duplicate]

Not as popular as the Copenhagen interpretation perhaps, but I'm truly intrigues to know the intricacies of the de Broglie-Bohm Theory. However, I could find absolutely no source which could teach me ...

In the pilot-wave theory, is the quantum potential moving electrons randomly inside atoms?

As we know, in the pilot-wave theory (Bohmian mechanics), particles are guided on certain trajectories by the wavefunction. Here (In Bohmian mechanics, do electrons move inside an atom?) I asked about ...

In Bohmian mechanics, it the uncertainty due to non-locality?

In the pilot-wave interpretation of quantum mechanics, each particle is driven by the pilot wave on the universal configuration space, and therefore its trajectory is determined nonlocally, and ...

In Bohmian mechanics, do electrons move inside an atom?

Look at http://www.bohmian-mechanics.net/whatisbm_pictures_hydrogen.html. It is mentioned that in the rest states of a bound electron, the position of the electron is stationary, since the ...

In a pilot-wave model, is knowing the position of the particle sufficient for predicting its behavior?

Suppose that we somehow exactly know the position of an electron before hitting the double-slit structure (for example we know it's 20cm away from the structure and it's closer to the left slit). In ...

Can quantum randomness be somehow explained by classical uncertainty? [closed]

In quantum mechanics, the outcome of each measurement is random, distributed according to the squared amplitude of the wave function obtained from the Schrodinger's equation. Now, can someone suggest ...

Can we have an arbitrary set of trajectories in Bohmian mechanics?

In Bohmian mechanics, the initial configurations and the pilot wave determine the future of the system. Given a set of initial positions for particles and a set of arbitrary trajectories, can we ...

What is the shape of the initial universal wavefunction?

In the many-worlds theory and Bohmian mechanics, the universe has an "initial" "universal" wavefunction which then evolves according to the Schrodinger's equation and determines the future of the ...

Does a pilot-wave theory need to be stochastic in a discrete space-time?

I have found an article about Bohmian mechanics on a lattice with discrete space and time, the link of which is given below: https://arxiv.org/abs/1606.02883 Here the motion of quantum particles is ...

How much is the amount of uncertainty in initial positions in Bohmian Mechanics?

In Bohmian mechanics, it is believed that the randomness (uncertainty, lack of knowledge) which is seen in the outcome of experiments is due to the uncertainty in the initial particle positions at the ...

Phase of a Wave and Phase Space

What relation does the phase of a wave have with the phase space? Namely, how are they related historically and/or physically? P.S. if it helps, I came across this question while thinking about the ...

In Bohmian Mechanics, is there a 1-to-1 relationship between particles and pilot waves?

In Bohmian Mechanics, do all particles have its own pilot wave, or can you have multiple particles on the same wave?

What happens with QM particle at constant velocity? [closed]

In QM particles have wavefunctions that disperse quite fast. The FWHM for gaussian wavepacket increases in time as $\Delta x(t)= \Delta x_0\sqrt{1+(t/\tau)^2} $, $\tau=2m(\Delta x_0)^2/\hbar$ What ...
