Query: Linear Response of a Periodically Driven Thermal Dipolar Gas   We study the nonequilibrium dynamics of an ultracold, non-degenerate dipolar
gas of $^{164}$Dy atoms in a cylindrically symmetric harmonic trap. To do so,
we investigate the normal modes and linear response of the gas when driven by
means of periodic modulations to the trap axial-frequency. We find that the
resonant response of the gas depends strongly on the dipole alignment axis,
owing to anisotropies in the differential cross section of the atoms. We employ
the use of the method of averages as well as numerical Monte Carlo methods for
our analysis. A striking result is that certain normal modes, termed "melting
modes", initiated in an anisotropic out-of-equilibrium configuration, relax to
equilibrium without oscillating.
