We calculate the dissociation and recombination rates of $$\mathrm{{\Upsilon}}(1S)$$ in quark-gluon plasma by using potential nonrelativistic QCD. We then study the dynamical in-medium evolution of the $$b\overline{b}{-}\mathrm{{\Upsilon}}$$ system in a periodic box via the Boltzmann equation and explore how the system reaches equilibrium. We find that interactions between the free heavy quarks and the medium are necessary for the system to reach equilibrium. We find that the angular distribution of $$\mathrm{{\Upsilon}}(1S)$$ probes the stages at which recombination occurs. Finally, we study the system under a longitudinal expansion and show that different initial conditions evolve to distinct final ratios of hidden and open $$b$$ flavors. We argue that experimental measurements of the ratio could address open questions in the quarkonium production in heavy ion collisions.
