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, how does the particle's position affect where a particle is detected?
In Bohmian mechanics / pilot wave theory / de Broglie–Bohm theory, my understanding is that a particle's trajectory evolves based on its wave function, and that the position that particle is detected ...

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 ...

Bosons in Bohmian mechanics
I would like to know if even bosons in the same quantum state, like in a BEC, can be discerned (by their positions) in Bohm's mechanics.

Loschmidt's paradox in Bohmian Mechanics
In Bohmian mechanics, the position of the particles must have a random distribution given by $\rho = |\Psi|^2$, where $\Psi$ is the wave function, in order to be compatible with Born rule in standard ...

How does Bohmian Mechanics explain superconductivity?
I'm looking for sources that discuss how Bohmian Mechanics explains superconductivity. Are there still Cooper pairs? Phonons? I saw one vague reference to vortices, but no details. This is my first ...

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 ...

Why does Bell's field theory model need to be stochastic on a space-time lattice?
In "Beables for quantum field theory", John Bell has presented a realistic interpretation of any fermionic quantum field theory, along the pilot-wave ideas. This model is formulated on a spatial lattice ...

What are the similarities/differences between the behaviors of Quantum particles and bouncing droplets? [duplicate]
Bouncing droplets on a fluid surface show many weird behaviors of the quantum world. Look at this for example:
https://arxiv.org/abs/1307.6920
They can show tunneling, double-slit interference ...

Does (Tomas) Bohr's modified double slit argument really doom Couder's quantum/classical fluid dynamics analogy?
I'm just an amateur, probably why I find the de Broglie/Bohm/Couder approach to QM compelling. But Copenhagen struck back: in a coincidence, Bohr's grandson is a fluid physicist who claims that ...

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 ...

How did Big Bang determine the initial conditions of the universe?
My question is that how did the Big Bang determine the initial distribution of the particles and their wavefunctions? In theories like Bohmian mechanics or Many worlds, how was the universal ...

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 ...
