In a weak coupling picture, the earliest stage of relativistic heavy-ion collisions is described by the Color Glass Condensate effective theory of high-energy QCD. The collision produces the glasma, a state of strong, overoccupied gluon fields far from equilibrium. In this talk, I will focus on the boost-invariant glasma, obtained using classical-statistical lattice gauge theory simulations.Heavy quarks and jets, produced at very early times, can serve as probes of the glasma. Their dynamics are governed by classical equations of motion for test particles in a collisionless Boltzmann-Vlasov plasma. I will present results from our colored particle-in-cell simulations, including jet and heavy-quark momentum broadening and the corresponding transport coefficients.Finally, I will discuss phenomenological implications of the glasma by emphasizing heavy quark-antiquark azimuthal correlations and compare classical jet broadening with our recent results from solving the light-front Dirac equation for quantum jets propagating in classical glasma fields.
