Abstract：
The energy spectra of heavy quark bound states are analyzed using the error-function-type potential and the one-gluon-exchange Coulomb-type force. The Debye screening mass at finite temperature and density is studied in the thermofield dynamics approach. The critical temperature and cridcal energy density for J/ψ dissociation in hot and dense matter are obtained.
