Calculate the entropy per atom in Bohmian Mechanics
Bohmian mechanics description of a large number of interacting atoms would require a large phase space due to the large number of classical degrees of freedom. The entropy per atom is given as the ...

Is Bohmian mechanics incompatible with Leggett inequality?
As far as I know violation of Bell's theorem is not a problem for De Broglie–Bohm theory because this theory is explicitly nonlocal; But since the violation of Leggett inequality is considered to ...

Can the Aharonov-Bohm experiment also be described by conditional probablilties, like the simple double slit?
The most attractive description of the double slit experiment for me is that in Beltrametti and Cassinelli's book.$^{[1]}$ The essence of their description is the following.
Beltrametti-Cassinelli ...

Can the pilot wave in Bohmian mechanics be derived from velocity-dependent potential?
In the derivation of the pilot wave, Bohm wrote the Schrodinger equation in this way:
\begin{equation}
\frac{\partial{S}}{\partial{t}} + \frac{(\nabla{S})^2}{2m} + V(x,t) - \frac{\hbar^2}{4m}[\frac{...

Is there a video of a double-slit experiment using walking oil droplets (aka dotwaves)?
I've heard there have been experiments with walking droplets in a double-slit setup, and I've seen videos of many of the other quantum phenomenons walking droplets can emulate, but I can't find one of ...

How does pilot wave theory expain delayed choice quantum eraser experiment?
I have heard that pilot wave theory adequately explains all quantum phenomenon and is an alternative to the more mainstream Copenhagen interpretation.
We have an experiment called the delayed choice ...

Measurement of Position in Bohmian Mechanics
In many formulations of Bohmian mechanics, researchers seem to claim that 1) measurements of observables such as spin are just measurements of the position of a pointer variable, such as the Stern-...

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 ...

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 ...

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 ...

Uncertainty Principle and Bohmian mechanics
The Uncertainty Principle is a relationship between measurements of pairs of attributes, position and momentum, as well as energy and time. Perfect precision of one attribute's measurement leads to a ...

How are can there be initial conditions in Bohmian mechanics that disobey the Born rule if Gleason's theorem is true?
Gleason's theorem constrains the possible measures that are allowed on Hilbert spaces of dimension $\ge 3$. It is often said that Gleason's theorem essentially says that the Born rule is the ...

Do I understand De Broglie–Bohm theory correctly?
In the interpretation of quantum mechanics developed by David Bohm (De Broglie–Bohm theory), the wave function is considered as a real-life physical field that evolves according to the Schrödinger ...

What is the ontological status of gauge fields/virtual particles/electron radiation in Dirac sea model of Bohmian QFT?
I have been reading about this model - it is a model without actual particle creation or annihilation, particles move deterministically according to Bohm's law, the Dirac sea is used to explain away ...

If we know the inital state of a quantum field can we predict its later state?
If we have the wavefunctional $\Phi[\psi]$ which tells us the probability density for finding $\psi$. Let's say we know the exact field state at $t=0;$ $\psi(x,0)$. Can we use the wavefunctional $\Phi[...
