    Bohmian Mechanics meets Neo-Lorentzian Ether Theory?

    Yes, the title of this thread has sounded the crackpot alarm! Anyway, I'm curious for your thoughts and suggested readings... As background, I've learned that Neo-Lorentzian Ether Theory is a valid alternate for Einstein's Special Relativity. This ether is undetectable, but does in imply a...

    Status of Relativistic Bohmian Mechanics: What Open Questions Remain?

    I am curious about recent progress in relativistic Bohmian mechanics. Finding a review is proving difficult (The closest I can find is a conference paper by H. Nikolic). My understanding is a set of dynamical variables are identified as "real" (beables), and their (usually deterministic)...

    Thoughts on Bohmian Mechanics?

    Hi, I'm an undergraduate in college, majoring in physics, and I just finished a course in Quantum Mechanics. I was left very disappointed with the interpretation presented, and this winter I am starting to do research with a professor in the field of Bohmian Mechanics. However, I am finding...

    Must position be continuous in Bohmian mechanics?

    Here I'm thinking of a single free particle obeying the Schroedinger equation. The ensemble refers to multiple experiments with a single particle in which the initial wave function is the same. If I naively imagine that there is such a thing as a wave function that is delta function, in...

    Legget's inequality and Bohmian mechanics

    Leaving aside the debatable point about whether bell's violation rules out all local theories or just local realism, is there general agreement that if the assumptions are valid, violation of Leggett's inequalities rules out any non-local model that treats properties other than position as real...

    Is Bohmian Mechanics incompatible with free will/choice?

    There has been some back and forth debate between Colbeck et al. vs. Ghirardi et al. on whether a recent no-go theorem by Colbeck and Renner would imply that Bohmian Mechanics is incompatible with free will/choice. I don't fully understand all the arguments but I thought I'd post them here in...

    Bohmian mechanics as 'complete' theory

    Hello, forum! I am puzzling my way through some interpretation. In the famous EPR paper, the authors ask whether quantum mechanics is a 'complete' theory in the sense of whether or not the wave function completely describes the physical circumstances in question. EPR conclude that it is not...

    Is Bohmian Mechanics deterministic?

    I've also heard that Bohmian mechanics is deterministic (eg. http://arxiv.org/abs/1206.1084, quote from Bell, p17). But in all presentations (eg. http://arxiv.org/abs/1206.1084, p30) I've come across so far, Bohmian mechanics needs an initial probability distribution. If probability over the...

    Do the SQUID experiments falsify Bohmian mechanics?

    In the experiments done with superconducting rings by Delft and Stony Brook, currents are shown to be moving in both directions simultaneously. Doesn't this falsify the idea that a pilot wave detemines a single evolution of the states? Can that be explained without the addition of multiple...

    Can you consider the particles in Bohmian Mechanics mixtures?

    The Refutation of Bohmian Mechanics

    Bohmian Mechanics conflicts with so many observational facts: 1. Bohmian Mechanics severely violates Lorentz Invariance because the wave function is simultaneously aware of all configuration changes of all matter in all locations in the entire universe at once (instantaneously and nonlocality...

    Quantum Potential in Bohmian Mechanics?

    What is the meaning of quantum potential in de broglie-bohm theory? Is that the "hidden variable"? Or are the positions of particles "hidden variables"? As far as I see, some references explains theory with quantum potential (Bohm, Holland) but some references explains it with guiding...

    Feynman and Bohmian mechanics (at the macroscopic level)

    I have just found out that Feynman also (re)discovered (some essential aspects of) Bohmian mechanics a long time ago, in his "Feynman Lectures on Physics" part III. Namely, in the last chapter devoted to superconductivity as macroscopic manifestation of quantum mechanics, he derives equations...

    Bohmian Mechanics and the two slit experiment

    I am trying to understand the essentials of the Bohmian interpretation of quantum mechanics (BI),and my (many) difficulties start with his description of the two slit experiment.As I understand it,Bohm asserts that every quantum particle has associated with it a quantum potential or guiding...

    Bohmian Mechanics: Do photons travel faster than c in double slit experiment?

    In the double slit experiment, Bohmian Mechanics http://plato.stanford.edu/entries/qm-bohm/#2s" the paths of real particles traveling from the two slits to the detector to look like something like this: The above image shows particles traveling in non-straight paths. The diagram below...

    The Pros and Cons of Bohmian Mechanics

    This is a discussion aimed towards gaining a better understanding of Bohmian Mechanics (BM) - at least on my part. I would like to see BM in the best light possible. My starting point in this journey is a reference to Sheldon Goldstein's summary in the Stanford Encyclopedia: Bohmian...

    Path integral formulation of Bohmian mechanics

    If Bohmain mechanics is true then the path integral: \int{d[\phi]}e^{(i/\hbar)\int_{a}^{b}Ldt where the Lagrangian is: L=(1/2)m(dx/dt)^{2}-V(x)+(\hbar^{2}/2m)\nabla^{2}\rho should be equal to its semiclassical expansion...(as in both cases are trajectories) my question is how would one...

    Bohmian Mechanics: Recent Readings & Experimental Evidence

    Recently, I read Bohm's articles explaining his interpretation of Quantum Mechanics. I did not find anything "bad" with it, so why didn't anybody pursue it further? Any experimental evidence against its predictions?

    Does Bohmian Mechanics Offer a True Alternative to Quantum Mechanics?

    in fact i think bell,s theorem says no, but i do not know if there are another thing that would allow it to be true..is bohmian mechanics true?...if not why people continues working on it...?
