Abstract
In this work, the position-momentum uncertainty of an excited two-level atom is analyzed for its time-dependent properties by taking into consideration the interaction between the atom and vacuum electromagnetic modes. For the purpose of comparison, the position-momentum uncertainty of a free particle is also considered. It is found that, because of the atom-field interaction, the uncertainty of the atom can be temporarily lower than that of the free particle.
