    A Bohmian Trajectories: Intersections & Young Experiments

    Oh yes i see now but can you elaborate?

    A Bohmian Trajectories: Intersections & Young Experiments

    is it possible a t = 0 that all the momentums are equal to p = 1_x> (unitary ane parallel to x) except in the plane y = o where the momentum would be 1_z> ?

    A Bohmian Trajectories: Intersections & Young Experiments

    please read the bottom of page 5 in Bohm's paper i repeat my question. Is there something that prevent two points in a small neighborhood to have orthogonal momentums (2 different trajectoiries might be tangent if they meet and exist!)

    A Bohmian Trajectories: Intersections & Young Experiments

    Geodesics can meet. Bohmian trajectories cannot. Bohm himself writes this It is in connection with the boundary conditions appearing in the equations of motion that we find the only fundamental difference between the psi-field and other fields such as electromagnetism

    A Bohmian Trajectories: Intersections & Young Experiments

    I am sorry. my question was very incorrectly asked. i wonder why in bohmian model two different trajectories cannot intersect. i know that the speed at one point in space time only depends on the configuration space point and that intersection of two curves would be a problem. but can two such...

    A Bohmian Trajectories: Intersections & Young Experiments

    i read that a bohmian trajectory (in this interpretation) cannot intersect itself because the speed depends on the position. there is no visualization problem in a Young experiment with trajectories from the slits to the screen. it becomes harder when a particle is trapped in a small region by a...

    B Superposition of traps (thought experiment)

    when we have screens on the paths we only have to open our eyes to see on which sreen the particle was. Suppose now that the traps are on the two paths and also on each side of a roberval balance. Have i only to open my eyes to see in which trap it is?

    B Superposition of traps (thought experiment)

    it might use a beam splitter but remember that it is only a thought experiment. It does not matter if there are no sufficiently precise measuring devices. my question is more about pure states or densitu matrices.

    B Superposition of traps (thought experiment)

    Hi Pf Instead of placing a screen on each path of an interometer i propose to place opticz traps. in both cases it will unable the photon to go further. i wonder if one on the traps will be heavier or if there will be symmetry (superposition).

    A Young's double slit experiment with excited atoms

    i come back to this paper. is it possible in this example to assign a density matrix to the state of this unstable atom? thanks

    I Historical basis for: measurement <-> linear operator?

    in 1925 people were mainly interested in the way things add (like waves) heisenberg faced another problem with spectrum rays. there was an addition rule for energy but no composition rules for the rays. the only thing that seemed real for him were the transitions (they can be observed) and he...

    I Historical basis for: measurement <-> linear operator?

    I thind that it began with Heisenberg's matrix mechanics.

    I Double slit one source same as no slits with two sources?

    can you give me a sentence in which you find a scheme? (i am not sure that this answer is for me)

    I Double slit one source same as no slits with two sources?

    you are right. the two cases are different in the case of the particle emitting a photon we have nothing to do. just wait for it.+
