Particle-Particle Simulation: Magnetic/Electric Fields & N-body Orbitals

  1. Jan 8, 2009 #1
    it is interesting i could not find many particle-particle simulators that simulate electrical fields even thought dynamics is pretty similar to that of planetary orbitals. there are few i could find but they are mostly 2D and defining problem in mathematical/geometrical terms, with sin/cos or some harmonic oscillator functions. none, however, i could find that simulate CLASSICAL ELECTRODYNAMICS (Stochastic El.Dynm. - SED) in 3D n-body system and even less to include MAGNETIC FIELDS, which are the effect of moving electric fields, says Lorentz and friends...


    this is kind of situation and type of particles i want to simulate: http://en.wikipedia.org/wiki/Magnetic_field

    You may have mused in the past, why one of my ....., or my girlfriend's .... is smaller than the other? well, look at that photo above, CHIRALITY is built-in. this universe is rather quier, it pulls on one side more than on the other. breaking of the symmetry...

    little twitching worms,
    all right, lets see how does it compare...

    in essence,
    i hope to be able to manage and somehow force these virtual atoms to aggregate with the use of "covalent bonds" by simulating it all with classical mechanics rather than quantum, which is contradictory to the "analog universe" somewhat....

    anyway, any idea? any similar software out there?

    Your post is very confusing.

    If this is ALL that you want to "simulate", then I'm thoroughly confused. This is nothing more than an electron beam in a uniform magnetic field. What is there to simulate? It is a very simple application of the Lorentz force equation, i.e.

    F = qv x B.

    Similar setup is used to measure the mass and energy spread of charge particles in spectrometers. In the scheme of things, this is not that complicated and requires no computer simulation at all.

    im sorry, what part do you find unclear?

    please, let me rephrase it, i would like answer to these questions:

    1.) what is the force behind covalent bond?

    2.) links and info about 3D n-body simulation software that deals with dynamics of charges and taking into account both electric and magnetic fields?

    3.) did you really think humans are on some "bottom" of grand scale of dimensions and that particle accelerators could be close to finding the fundamental-indivisible particles?



    that is not all, i want to simulate Life, Universe and Everything, but the first problem at hand is to simulate - covalent bonding - of hydrogen atoms by simulating classical mechanics rather than quantum, would you know about anything like that?

    simple or not,
    can you point some links to some software that does this in 3D with n-body system, just like in those YouTube videos in OP?


    thanks

    This is getting weirder. What makes you think that you can "simulate" something like molecular bonding using classical physics? If that's true, there would be no need for quantum mechanics.

    Chemistry came into existence WAY before quantum mechanics. While they could see the effect, they have no way to explain why. It was until after QM came into existence that many of these observations could be explained and quantitatively described.

    Classical N-body system does not show any resemblance to QM many-body system. Try deriving superconductivity, for example, which is a prime example of QM many-body system.

    You still haven't addressed the fact that THAT picture that I quoted is nothing more than a simple Lorentz law. So what were you intending to "simulate"?

    Zzzz,


    my comment for the picture was:
    -this is *KIND OF* situation and *TYPE OF* particles i want to simulate

    then, i have addressed it second time when i said that im trying to simulate *COVALENT BONDS* (simple 4 particle simulation - 2 electrons and 2 protons forming 2 hydrogen atoms and then bonding with covalent bond in H2).


    if you have further questions of your own then please start a thread and i'll come there and answer all your questions. but, since this thread is about my questions its only fair these to be answered first:


    1.) what is the force behind covalent bond?

    2.) links and info about 3D n-body simulation software that deals with dynamics of charges and taking into account both electric and magnetic fields?

    3.) did you really think humans are on some "bottom" of grand scale of dimensions and that particle accelerators could be close to finding the fundamental-indivisible particles?



    sorry, what part confuses you?



    experience.

    but i do not need to be able to predict outcome, this is *simulation* - it is a way to experiment, so i will try this nevertheless just because i can... and because it has never been done this way before. i simply have to do this, who else?




    ok, thanks. i suppose you are not aware that classical mechanics can indeed be used to model atomic and molecular interactions with the similar results and predictions as quantum mechanics. thought, im not expert on classical approach, i believe the most popular ones deal with "electron radiation".



    now, do you think you can try to answer these:

    1.) what is the force behind covalent bond?

    2.) links and info about 3D n-body simulation software that deals with dynamics of charges and taking into account both electric and magnetic fields?



    unless you try to provide some answer to Q2, you will never understand what im talking about - my approach is NEW, this has not been tried, ok? but, feel free to show me otherwise.



    anyway, i hope you do not have any more questions for me until you at least try to answer some of mine:

    3.) did you really think humans are on some "bottom" of grand scale of dimensions and that particle accelerators could be close to finding the fundamental-indivisible particles?

    You have posted a lot of unverified and speculative issues here. In case you missed it the first time you signed up, please review the PF Guidelines that you had agreed to. Please provide valid references from peer-reviewed sources to back up your claim, especially this one.

    You may send it to me via PM. Till then, this thread is in violation of the guidelines and is locked.
