Query: Periodic thermodynamics of the Rabi model with circular polarization for
  arbitrary spin quantum numbers   We consider a spin $s$ subjected to both a static and an orthogonally applied
oscillating, circularly polarized magnetic field while being coupled to a heat
bath, and analytically determine the quasi\-stationary distribution of its
Floquet-state occupation probabilities for arbitrarily strong driving. This
distribution is shown to be Boltzmannian with a quasitemperature which is
different from the temperature of the bath, and independent of the spin quantum
number. We discover a remarkable formal analogy between the quasithermal
magnetism of the nonequilibrium steady state of a driven ideal paramagnetic
material, and the usual thermal paramagnetism. Nonetheless, the response of
such a material to the combined fields is predicted to show several unexpected
features, even allowing one to turn a paramagnet into a diamagnet under strong
driving. Thus, we argue that experimental measurements of this response may
provide key paradigms for the emerging field of periodic thermodynamics.
