  We study the impact of the Glasma fields, used to describe the very early
stage of heavy-ion collisions, on the transport of hard probes, namely heavy
quarks and jets. We perform numerical simulations of the strong classical
fields using techniques from real-time lattice gauge theory. The resulting
fields are used as background for the classical transport of ensembles of
particles, described by Wong's equations. For this purpose, we develop a
numerical solver for the transport of the probes, based on colored
particle-in-cell methods.
  We focus on the dynamics of heavy quarks and jets in the classical colored
fields. To quantify the effect of the Glasma, we extract the momentum
broadening of hard probes and evaluate the anisotropy transfer from the Glasma
to the probes. Lastly, we evaluate the heavy quark $\kappa$ and jet $\hat{q}$
transport coefficients in the Glasma, which turn out to be large and exhibit a
peak, irrespective of the particle initialization.
