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 ...

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 ...

Non-locality of the Madelung equations?
As far as I understand, the Madelung equations
$$
\frac{\partial \rho}{\partial t} + \nabla \cdot \rho \mathbf{u} = 0 \\
\frac{\partial \mathbf{u}}{\partial t} + \mathbf{u} \cdot \nabla \mathbf{u} = -\...

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 ...

Pilot-Wave vs. Quantum Mechanics vs. String Theory [closed]
I wanted to know that are the main shortcomings of contemporary Pilot-Wave theory which is holding it back from dominating physics departments? To what extent is the facukty biase, do you think, ...

Bohm's view of double-slit experiment, wave-particle duality
I gather that Bohm denies the notion that the act of measurement decides whether a photon will be a wave or a particle. Bohm's idea seems to be that the photon is always a particle with a real ...

Would pilot-wave gravity reconcile Bohmian mechanics with relativity? [closed]
I was reading Can Bohmian mechanics be made relativistic? from 2016 that attempts to reconcile Bohmian mechanics with relativity. It’s conclusion says:
Is such a theory then fundamentally—and/or ...

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 ...

Is Bohmian mechanics wrong in the case that space and time are quantized?
Bohmian mechanics assumes that particle trajectories are continuous. Also, it claims the random outcome of certain experiments (like the double-slit experiment) to be due to the random initial ...

Do we have a potential (quantum) in Bohm quantum mechanics that is associated with the phase factor $S$?
In Bohm quantum mechanics when we express the wavefunction as $\psi= R \exp(iS/\hbar)$ a quantum potential that depends on R is found, is there another potential that depends on the phase function S?

Could two particles be released in parallel to test if their quantum probability waves interact, showing whether pilot waves exist?
What if you just release two streams of particles next to each other in parallel? Then you don't even need the double slits. See if their waves interact, and you'll know whether pilot waves are real ...

Does Bohmian mechanics really solve the measurement problem?
I'm working a lot on Bohmian mechanics related theories and just realised something that had escaped me until now but actually seems to throw a wrench in the core idea of the theory. I tried to ...
