Query: Mourre Theory For Time-Periodic Magnetic Fields   We study the Mourre theory for the Floquet Hamiltonian $\hat{H} = -i
\partial_t + H(t)$ generated by the time-periodic Hamiltonian $H(t)$ with
$H(t+T) =H(t)$, which describes the Schr\"{o}dinger equations with general
time-periodic magnetic fields.
