Time dependant Hamiltonian

  1. May 12, 2008 #1
    Hi all!
    I'm starting to study the time evolution operator, and now i came up with this objective... i need a time dependant hamiltonian! since no fundamental interaction is time dependent i need to think of a system in such a configuration that i have a time dependency on H.
    Anyway, if anyone has any idea i'd be very happy to discuss them! :D

    Not fundamental, but effective: An electron in a rotating magnetic field:
    [tex]\mathbf{B}(t) = sin(\omega t) \mathbf{x} + \cos(\omega t) \mathbf{y}[/tex]
