Query: Approximate solution of the time-dependent Kratzer plus screened Coulomb
  potential in Feinberg-Horodecki equation   We obtain the quantized momentum eigenvalues, $P_n$, together with space-like
coherent eigenstates for the space-like counterpart of the Schrodinger
equation, the Feinberg-Horodecki equation, with a combined Kratzer potential
plus screened coulomb potential which is constructed by temporal counterpart of
the spatial form of these potentials. The present work is illustrated with two
special cases of the general form: the time-dependent modified Kratzer
potential and the time-dependent screened Coulomb potential.
