  We investigate the dynamics of a strong first-order quark-hadron transition
driven by cubic interaction via homogeneous bubble nucleation in the
Friedberg-Lee model. The one-loop effective thermodynamics potential of the
model and the critical bubble profiles have been calculated at different
temperatures and chemical potentials. By taking the temperature and the
chemical potential as the variables, the evolutions of the surface tension, the
typical radius of the critical bubble and the shift in the coarse-grained free
energy in the presence of a nucleation bubble are obtained and the limit on the
reliability of the thin-wall approximation is also addressed accordingly. Our
results are compared to those obtained for a weak first-order quark-hadron
phase transition, especially the spinodal decomposition is relevant.
