Description

We use the density matrix formulation to study the dynamic of atom-photon interaction of Rb-85 atoms under the cooling and repumping laser fields in a magneto-optical trap (MOT). The spontaneous emission process is taken into account using the fully-quantized theory. The obtained master equations are numerically solved for the four-level system including two levels of $5^2S_{1/2}F=2,3$ and two levels of $5^2P_{3/2}F=3,4$. The steady solution that naturally gives the probability of finding trapped atoms occupying each level in MOT is analyzed in detail.
