B If an imaginary quasiparticle has a mass depending on speed

  1. Dec 8, 2016 #1
    ...becoming infinite at rest, doesn't that mean it has infinite mass whatever velocity it has?

    How could that quasiparticle be at rest to achieve infinite mass?

    Your scenario has no physical basis. There is no way to answer your question.

    What do you mean by "an imaginary quasiparticle becoming infinite at rest"? What source are you getting this from?

    Mass is defined as the energy a particle has, when it is at rest. Therefore, it makes no sense to speak of a velocity dependent mass.
