      abstract     = {We describe bottomonium production not only in pp
                      collisions but also in heavy-ion collisions by using the
                      Remler's formalism where quarkonium density operator is
                      applied to all possible combination of heavy quark and heavy
                      antiquark pairs. In pp collisions heavy (anti)quark momentum
                      is provided by the PYTHIA event generator after rescaling
                      $p_T$ and rapidity to imitate the FONLL calculations. Then
                      spatial separation between heavy quark and heavy antiquark
                      is introduced based on the uncertainty principle. In
                      heavy-ion collisions quarkonium wavefunction changes with
                      temperature assuming heavy quark potential equals the free
                      energy of heavy quark and heavy antiquark system in heat
                      bath. The density operator is updated whenever heavy quark
                      or heavy antiquark scatters in QGP produced in heavy-ion
                      collisions. Our results are consistent with the experimental
                      data from ALICE and CMS Collaborations assuming that the
                      interaction rate of heavy (anti)quark in quarkonium is
                      suppressed to 10 \\% that of unbound heavy (anti)quark. We
                      also find that off-diagonal recombination of bottomonium
                      barely happens even in Pb+Pb collisions at $\sqrt{s}=5.02$
