Binding Energies and Dissociations of $J/\psi$, $\Upsilon$, and Toponium   in Quark-Gluon Plasma
  In this work, we calculate the binding energies of the $J/\psi$, the $\Upsilon$, and the Toponium in quark-gluon plasma. We also calculate the temperature of the quark-gluon plasma at which these quarkonia dissociate. We approach the problem from a quantum mechanical point of view. We use the variational method and the screening Debye potential in order to obtain these binding energies.
