Superpositions and strong force

  1. Feb 24, 2016 #1
    I'm a bit confused now i understand that when one observes a particle for example @ Eigenstate A all its superpositions collapse because they are entangled with A which leaves them no longer entangled. My dilemma and maybe you can help me, is that If you observe a complex structure of sub atomic particles @ Eigenstate A. which of course is bound together by strong force , its superpositions collapse because those particles are entangled to A/ leaving them no longer entangled to any eigenstate or superposition! Heres the problem i have
    if strong force was functioning on those complex structures of sub atomic particles in eigenstate A prior to observation and wave function collapse why would strong force just stop function after wave function collapse... shouldn't those particles remain bound by such after observation and WFC. any thoughts on such would be appreciated

    The particles would indeed remain bound after the wavefunction "collapse". The strong force governs the Hamiltonian that describes how the wavefunction will evolve in time. It's the Hamiltonian that describes the dynamics of the system, while the wavefunction is just the system's current state. This is why, for example, a cat in an isolated box wouldn't literally dissolve into a miasma of cat particles after someone looks at it.

    I expect that shortly after collapse, the Hamiltonian describing the strong force will show that the particles will become entangled with each other again as they interact over time (a very small time scale, I expect).
