How does the superposition of states come up in Bohmian Mechanics?
In Bohmian Mechanics, it assumes a universal wave field in which particle's motion can be calculated using Newton's law of motion:
\begin{equation}
m\frac{d^{2}x}{dt^{2}} = - \nabla(V+U)
\end{...

De-Broglie Wavelength and the Pilot Wave Theory
I researched a lot of questions on De-Broglie waves on this website and discovered a dense fog of confusion amongst everyone. Louis De-Broglie proposed "Matter Waves" and a simple equation describing ...

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 ...

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.

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 ...

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 ...

Is there a name for Bohmian pilot wave theory with an ensemble of jockey particles?
In Bohmian QM, the wave function $\psi$ is moving a classical point particle around. Without effort, it could also move a large
ensemble of particles (since there is no back reaction).
Is there a name ...

Particles in an interferometer in a gravitational field
Let's assume one has a standard interferometer, consisting of an incoming beam which gets splitted in beam I and II and then culminated again. Now the interferometer is placed in a gravitational field,...

Why can we not know the position of a particle in Bohmian Mechanics?
I can't seem to understand this. In Bohmian mechanics, particles have definite positions and are guided by a wave function governed deterministically by Schrodinger's equation. So if you knew a ...

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 ...

Is 'measurement' deterministic in the pilot wave theory?
From what I read, measurements in pilot wave theory affect the particles as well as the guiding waves. Is it a random process or is everything deterministic according to the theory?

Does this thought experiment proves that Standard Quantum Mechanics and Pilot Wave Theory make different predictions?
Here is a thought experiment that is supposed to show that standard quantum mechanics and pilot wave theory do not make the same prediction :
Take the double slit experiment, and add a detector in ...

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 ...

If Pilot wave theory turns out to be the correct way of interpreting quantum mechanics what are the implications?
I've read a few articles on Pilot Wave theory. Part of the theory describes how particles have a deterministic path and particles can't be in two places at once. If this turned out to be true would ...
