Quantum Brownian Motion.

  1. Jul 2, 2013 #1
    Hello EVERYBODY! :)
    I have a question: Does the frequency of virtual particles (apparition/disappearance) match with nucleus random path - known as Quantum Browniαn Motion?

    Thank you in advance! ;)

    What do you mean with "frequency of virtual particles"? Virtual particles are a tool in calculations, they are not real.

    How often they pop in/out of existence.
    And actually they exist.

    As I said, that is not a meaningful question.
    You cannot say "see! there was a virtual particle". They are a mathematical tool in quantum field theory.

    So if it is not about virtual particles, then what is the cause of Quantum Brownian Motion?

    I mean the what is the cause of the "nucleus random path"? And who are those particles?

    Everything around the particle you consider (that is an answer to both questions).

    Their mass must be very very small (smaller than relativistic mass of photon).
